A permanent station GNSS reference RTK radio can transmit data directly to RTK receivers. The station will be monitored by a program running on a computer and will also allow the downloading and archiving of recorded data. Working radius of about 30 km is usually sufficient in this case and provides accuracies required. In special cases you can install a second or more permanent stations GNSS reference in order to ensure the attainment by two independent positions RTK receivers for determining certain critical points. In this case one computer (server) can provide control for all permanent stations GNSS reference.

To ensure accuracy centimeter networks Geodetic created by observation satellite, use and currently permanent stations temporarily, by installing a receiver in a network point and keep it fixed over several work sessions, or even for a whole day of observation. For relative positioning with high precision observations were used only in a situation where measurements were held near these stations in order to ensure control over the base length dependent bias. When designing permanent reference station networks GNSS is envisaged to serve a wider range of users, the optimal distance between these stations considering between 30 and 50 km.


This density is now regarded as insufficient. Network of permanent stations Cell Phone Tracker reference to US currently consists of 38 stations, the average distance between them is about. 200 km. A potential user of observations from these stations may be in the most unfavorable situation, about 100 km all GNSS reference stations standing around him. It is obvious that the holders of L1 receivers will not seek observations from these stations, with no possibility of control over the base length dependent errors. To avoid this inconvenience, technical positioning network of permanent stations sparsely been directed towards the realization of virtual reference stations.
This solution is a way to use all the information in real observations from permanent stations. The comments generated by virtual computing stations have much better characteristics compared to actual observations were carried out at these points as characteristic errors station (multipath, cycle-slip, refractions on the outskirts of obstructions) no longer exists. The functional programs that generate comments virtual stations using either linear equations to be an observation phase double difference equations. For generating virtual stations observations are necessary theoretical framework of this station, which is usually choose the center of your work area.

Data from neighboring real permanent stations are centralized on a single computer observations and worked jointly estimating ambiguities for each satellite in hand which is then extracted from the observation equations. Resulting equations containing only comments corrections, so equations reduced by satellite-receiver distance. If all observations have been reduced to a single station, the corrections obtained can be used to interpolate corrections for any other station on the network.
In the second phase, the information obtained is used to generate the virtual station accurate observations. The most difficult problem here is the modeling correct errors of observation. The modeling is done independently for each satellite in part, using flat correction, which corresponds to a two-dimensional linear interpolation. If three base stations are used the actual surrounding a virtual reference station, they form a triangle, and the area is uniquely determined by interpolation. Correction surfaces are described by two parameters that describe the interpolated surface tilt directions North and East. Modeling the influence of ionospheric refraction modeling is independent of the influence of tropospheric refraction errors and orbital so that each surface interpolation parameters are obtained in April expressed in ppm. Ionospheric refraction corrections to refer only to L1 signal.
In conditions in which all calculations are performed centrally, just a user to transmit the position of station virtual work area, being the offered remarks station virtual RINEX format, which can then be processed together with observations of real network, using a joint post-processing of satellite observations.

The great advantage of this technique lies in the fact that the short base is determined, which can be processed even for receivers with L1 frequency. This technique would be to create a solution and geodetic observations points higher order located in the woods, where they can make real observations in points in very inaccessible areas, or areas that were destroyed.

Snapchat function tests live video on iPhone

Snapchat live video to test the function iPhone users worldwide, and below you have a picture of the interface to be available. The folks at Facebook have implemented the ability to do live video on any mobile device or computer, and now function will arrive in network Snapchat users. Live video function has proved to be extremely popular in the social network Facebook, and now a US company brings in Snapchat, which also owns the network. Snapchat integration with live video, users will be able not only to publish pictures or videos, but will be able to broadcast live video. For now Snapchat users in Russia can make live video sessions and all assets appear in the segment in which sites are displayed stories of the day. Snapchat live video sessions are marked with a special button called LIVE, restoring their access video stream that the user wants to send in that time, just like on Facebook.

Moreover, snaphack users with access to live video and have a button called Insta Go that allows them to initiate a live video stream via Snapchat. Those from Snapchat refused to confirm that the test function and nobody knows when it will be released, but at least we know it is under development.

The popularity was never guarantee security, more so today, when multiplied warnings on precarious security social network Snapchat images, belonging and Facebook has over 400 million subscribers. Belgian researcher Arne Swinnen, specializing in such security issues discovered one nine loophole that allows piracy Snapchat accounts by changing the user’s phone number.

Since then Snapchat reacted to Belgian researcher finds and corrects gaps. So fastened by a limited number of requests and too simple passwords are no longer supported. Aren Swinnen received rewards for helping the social network. When accounts are attacked, they can be exploited to send spam and malicious links by millions of followers, paving the way for leaks embarrassing nude photographs, as happened in 2014 in the case known as’ Celebgate ” . Then about 500 private photos of celebrities like Jennifer Lawrence, Christina Hendricks and Anna Kendrick, fraudulently obtained as a result of computer breaches were posted illegally online.

Snapchat application has been updated this evening by the company with the same name, two new important functions were implemented for users worldwide. The first is a zoom function that can be used while recording video clips by dragging your finger up the screen, so you will see pictures of the network closer. The second important function will allow us to record pictures and videos much better in low light conditions change being one auspicious. Snapchat application interface has pictures and recording video clips by pressing a special button that activates a digital software module that will brighten everything is recorded.

If until now, Google turned to Motorola, Huawei and LG to produce and sell the Nexus phones, the new Pixel series will be manufactured by HTC, and phones will be sold exclusively branded Google Pixel.

According to sources, Google Pixel will include a quad-core 2.0GHz processor, 64-bit, 4 GB of RAM, an 8 MP camera selfie IMX179 (same Nexus 5) and another main 12 MP IMX378 with autofocus and stabilization on three axes, both produced by Sony. the phone will mAh battery 2770.

Google will Pixel model would include a larger battery of 3450mAh. The two phones will have USB-C and quick loading.

The cheapest Google Pixel, 32GB would cost $ 649. There will be 64 and 128 GB versions. Pixel XL will be priced at least $ 150 higher, sources say.

Google launched on this occasion, and a dedicated website where will be posted information about the new Google phone Pixel.

During the event on 4 October, Google will launch the new generation Ultra Chromecast, which are details HERE. Now in its third generation, cheap and efficient device which allows wireless streaming Chromecast Ultra will be baptized and will facilitate the transfer of 4K video content.

It is possible that the Google conference, to be launched and new virtual reality helmet Daydream VR and be given information about virtual assistant based on artificial intelligence, Google Home.

Pokemon Blue 4

The first generation of Pokemon is back, not to play a bad turn, but to offer collectors and fans to discover and rediscover the 151 Pokémon (and yes, we count Mew) originals that delighted lovers of the time. This release seems all the more logical as this first generation was available in Pokemon X and Y. It’s gone for Pokemon Blue!

Welcome to Bourg Palette

From the beginning of the adventure, memories of recreation courses return: the joy of capturing a pokemon, the distress of a defeat of an arena fight … We begin the adventure in Bourg Palette, where , After having met Professor Chen, proposes to us to choose between 3 pokémons of departure: Salamèche, Carapuce or Bulbizarre. I chose the little Salamèche. After a few round trips, we are immersed in the world of Pokemon, where small monsters are to be captured and trainer fights are to win to ultimately win the Pokemon league, and become Master Pokemon.

The gameplay, 20 years later, has not moved from one iota: 6 pokemon in our bag, 4 skills per pokemon and a turn-based combat system, in order to capture more pokemon or beat More or less tough. It will be necessary to pay attention to the weaknesses and strengths of each pokemon depending on their element characterizing them most. It must be admitted that 20 years later, some originalities of gameplay introduced more recently miss and make the title more repetitive than one would think. For example, the non-presence of fights with several pokemon or more recently the clashes against the hordes and the usefulness of the objects held by the Pokemons is really felt.

But as rustic as it may seem, this first generation is still staying stable and addictive, our desire to capture and possess all the 151 creature is intact. The music is untouched, we find without much concern the side madeleine of proust with which Nintendo has been playing for some time with each release of a game on its Virtual Console, we find here the most outstanding themes still trotting us today In the lead to the simple evocation of Pokemon. Besides, it will take several dozen hours to capture all the creatures, but also to make them experience, to make them fight, to find all the objects of the game, but also to exchange them.

Pokemon Blue 4

Nintendo offers us with this version 3DS, an internet connectivity to small onions. It is possible for you to store your pokemon in the pokemon bank, and to recover these pokemon on your other 3ds pokemon games (X and Y, RO and SA, and the future Moon & Sun). Moreover, we are allowed, as at the time, to challenge and exchange pokemons, not thanks to the Cable Link, but thanks to a wireless connection between two 3DS. It will of course be necessary that each console has a Virtual Console version installed on its 3DS. The procedure will be the same as at the time and you will have to go to a pokemon center, and talk to the right hostess, who will give us access to the multi. Download pokemon sun rom:

It is this aspect that gives its main interest of this outlet of blue pokemon because apart from the possibility of having these 151 pokémon in our present games to fight the world in multi, this version has only attraction. First of all, we must already be careful in the 3DS shop to buy a version corresponding to the language we speak, otherwise we will have to go back to the cashier, it is expensive the language pack anyway. Moreover, the game is not even optimized graphically on the screen of the 3dDS, my original on cartridge is prettier on my Game Boy Color and my Game Boy Advance SP. It’s still crazy that Nintendo is not able to offer a better version than a simple rom of his game recovered from a database server. It would have been nice to also offer Game Boy Advance remakes, with a passage from one version to another, as do the remasters of Lucasart games, for example. Especially since Nintendo has communicated a lot on this subject, with as a bonus the release of special editions of their New 3DS and 2DS in the colors of the game and containing this one.

Pokemon Blue Version remains a cult and historical game, demonstrating the power of Nintendo in terms of creator of universe and gameplay. The youngest ones will be able to rediscover the world of small monsters with the first generation still today cult. It is however a pity that for the price practiced to the purchase, one finds only with a game without addition in comparison to its original Game Boy.

Locating phone: how can it be avoided?

Because the operative situation often requires locating a mobile phone fast and real-time intelligence not always resort to cooperation with network operator to locate the phone. They use special equipment location, and works only in conjunction with mobile devices to intercept phone. Localization process by this method is not simple. Interceptor is necessary to be placed in proximity mobile phone monitored remotely from 100-800 meters (in urban areas).

The phone will automatically connect to the network generated false interceptor, along with dozens or hundreds of phones. Interception equipment operator has the option of connecting mobile filtration and rejection operative who shows interest, but only in situations where identification of phone and SIM card are previously known (IMEI, IMSI). After attracting phone network, start the actual process of localization, which can be carried by several principles, depending on design and device location features.

Modern phones can be installed with or without the will of the owner, a range of software localization is intended solely phone or who and location functions. The range is extremely wide, from applications of socializing which leaves the user the option to disclose their location to friends, applications for locating your lost phone (Phone Numer Tracker is a good example) and applications such as spy that are invisible phone GSM and GPS position and transmit the monitored phone along with other confidential data.

Using the latter is generally illegal. Users of these applications generally remain unsatisfied with the results, a very simple reason: the phone’s location on a digital map is simple marker location. In urban areas it does not show the address, building, floor and apartment number as they would like most users. Even after an accurate GPS locations, a marker next to a block of flats can not reveal many details about the exact location of the phone when it is a cheating wife, for example. Shortcomings and leave the GPS data not available when the phone is monitored in a building, for example.


There are times when we wish that the phone can not be located by any of the methods described above. You should know that a classic phone user – whether smartphone or not – has no chance to avoid the location of your phone unless it closes. GPS spoofing various solutions are unsafe and applicable to a small number of mobile phones, being dependent on a software, phone model and operating system type. Receiving pings location is invisible on any ordinary phone and it can not be blocked than the handset. This function serves to alert the user when the phone receives an abnormally high number of queries or requests for authentication (registration) in the GSM network. Interceptors GSM or GSM (as a share of the GSM operator) may request these records in a very high rate, to locate the phone and / or extraction and calculation of the encryption key Kc that are stored on the SIM, the key will be used decryption and later in telephone tapping. The default setting is 2 successive pings in an interval of 60 seconds. If the phone receives more than two pings location in a minute, the alert will be triggered localization.
This function serves to lock your phone on a specific ARFCN (pair of radio channels through which the phone communicating with BTS, uplink and downlink called) GSM cell phone is stationary. A GSM interceptor will always have a stronger signal than the STD’s that are connected telephones to determine their automatic connection of the interceptor and execution interception and SMS. To connect mobile force, will have a wing GSM ARFCN (see glossary of terms at the bottom of the page) BTS different from the original. Activating the locks connecting the phone to GSM wing and in this way will eliminate the possibility of interception. This function can be used only when the phone is stationary, because thanks to the GSM network architecture, ARFCN the change from a GSM cell to another when the phone is in motion.

Described how simplistic, global monitoring system involves the installation of special equipment generically called “SS7 Box” (a hybrid hardware-software high tech “universal modular software platform signaling”) every national GSM operator. Acasta company that delivers monitoring solution has ongoing contracts with the majority of mobile operators in the world, installing almost each of them, an SS7 Box. Each SS7 Box is also connected to an external server GSM operator, usually belonging to the same company that delivers monitoring solution. SS7 Box’s installation is done with the consent and approval national GSM operator and at the request of that country intelligence services which are party and beneficiary of global service locator phones.

The discoveries of humanity – Electricity

The discoveries of humanity – Electricity



People live differently now more than 100 years before being discovered electricity. First they talked about electricity in history were the Greeks 2000 years ago. They noted that friction causes the amber fur attraction between the two.

In 1600, English physicist William Gilbert (May 24, 1544 – November 30, 1603) coined the term “electric”, derived from the Greek “elektron” to identify emerging force between two objects rub against each other. Gilbert used items were amber and a magnet, thus registering for the first time the word “electric” in a report about the theory of magnetism.

It is said that in 1752, Benjamin Franklin (January 17, 1706 – 17th of April 1790 the US) did a famous experiment at flying a kite tempest with silk top which sank a key iron. The experiment proved Franklin’s theory later but was very dangerous, he can be killed by lightning. This breakthrough has induced the idea that light and electricity are closely connected, later leading to the invention of the lightning rod. Benjamin Franklin’s face is placed prominently on US 100 dollar banknote.

In 1786, Luigi Galvani, an Italian professor of medicine noted that a frog leg kicking violent death when touched by a metal knife. He thought that the frog muscles are carriers of electricity.

In 1792, another scientist Alessandro Volta Italian contradicted him on Galvani’s discovery saying that the main factor is achieving the two metals: knife, metal tray that was lying frog. Volta showed that when we talk about humidity between two different metals, electricity is created. This phenomenon led him to the discovery of the first batteries, voltaic cell made of thin sheets of cupule and zinc, separated by a wet cardboard (hence the name of the unit of measure, Volt).

A great contribution to the theory of electricity had it but the Englishman Michael Faraday (Newington, September 22, 1791 – London, August 25 1867). He found that when you put a magnet in a coil of copper wire, a tiny electric current flowing through wires. It is the first method of generating electricity through movement in a magnetic field.

Sir Joseph Swan (October 31, 1828, Pallion, UK – May 27, 1924) invented the filament lamp incandescent (light) although many books and I give the inventor the popular Thomas Alva Edison (February 11, 1847 – October 18, 1931) American citizen and businessman. Edison invention registered in the US Patent Office (the only authority recognized American invention) based on a design of Swan made ten years earlier. When he learned, Swan sued him and won Edison. US Patent Office invalidated the patent to him Edison and forced him to take on Swan partner in his company. Together they managed to develop an electric lighting system that contained all the necessary elements to practical use, safe and economically incandescent light. Swan and Edison managed together to illuminate for the first time in history an electric street lamps or bulbs. It happened in September 1882 in New York.

Nikola Tesla (July 10, 1856, Smiljan Lika, Croatia – January 7, 1943, New York) is considered the “father” of today’s wireless devices. Tesla has patented engine generating AC and it seems that he sold his invention to George Westinghouse (which has and employee). At 30 he emigrated to America and was employed at the company’s Thomas Edison. There was an agreement with Edison revolt against the way in which the latter leading scientific research, has resigned and has decided to work for himself. In 1891, after the success of its system based on alternating current, Tesla transformer realized that bears his name today. This allows to obtain voltage transformer with values of up to several million volts.
