Yesterday started three GLONASS satellites launched in early March, (European Russia covered their signal at 100%)

Official page with information about the composition of the group of GLONASS satellites (and also peeep-the cast, made to the case of garraffello) shows that yesterday (March 28) started all three phones launched on March 2 from the Baikonur cosmodrome in near space.

According to the map posted on one of the neighboring pages, the current GLONASS constellation, due to its incompleteness (there are 20 satellites, and it is necessary 24) is not yet able to provide the navigation signal to the whole world. However, a large part of Russia is already providing satellite navigation for the 100% of the time of day, and in other parts of Russia (on the map marked in yellow) shortages of navigation is not more than 5% days (about an hour). It looks like this:

In particular, today one hundred percent availability of the navigation signal can rejoice the inhabitants of European Russia and Western Siberia. In the future, the area will gradually shift along the surface of the Earth as a smooth circulation system of satellites in near-earth space.

Further replenishment of the GLONASS spacecraft is scheduled fall two launches for three satellites in each. number — yet unprecedented experimental satellite, which provides twice the accuracy of navigation that does not require sealing, able to work in orbit for ten years in a row. Currently, he is a series of ground tests.

ODBC Firebird, Postgresql, executing queries in Powershell

Изображение
Sometimes, system engineers may need to obtain specific data directly from the DBMS by means of Powershell. In this article I want to demonstrate two methods of operating firebird, postgresql through the odbc driver and client library. let's Start with the firebird and work with the database through the ODBC driver, you first need to register in the system client library GDS32.DLL, its bit width should be the same as the ODBC driver which should be installed next, download on the manufacturer's website , be sure during installation you need to tick on the registration of the library. Next install itself ODBC, who also take on the manufacturer's website , do not forget that the bit size should match the bit count of a previously installed client. Now actually have a powershell script, it was based on example in C# for postgresql. the $dbServerName = "localhost:base.gdb" $dbUser = "SYSDBA" $dbPass = "masterkey" [string]$s

Изображение
this weekend, Kiev will host a very cool event Garage48 — the idea is that for two days to create a startup. In the “create “ includes everything needed to present your business idea, qualify, technically, to bring it to life, and then be able to sell it to strict spectator and wise mentors. This event was invented in Estonia and has already managed to visit many countries of the world. Finally, Garage 48 has reached the Ukraine: from 11th to 13th may we occupy the Library of KPI , which is located on the Avenue Victory 37 and start enjoying foreign mentors (they will guide you in the right direction to create a startup and guide you on the right path, if you go into the jungle), as well as the company of their colleagues and event organizers — representatives of Garage48 Foundation And IT DOU-activist Vicky Zorbas. On Friday we will get acquainted with the ideas of the participants, will select the best ideas and form teams. Saturday morning will see which team surv

The Ministry of communications wants to ban phones without GLONASS

Today in the Ministry of communications submitted the bill , according to which in Russia it will be possible to use only those mobile phones that include support for the GLONASS navigation system. Although it is not clear how this will be monitored, most likely, we are talking about banning the importation and sale. This decision was taken in order, and I quote in order to ensure the stability of the unified telecommunication network of the Russian Federation in various conditions. Requirements (in the case of the adoption of this act) will apply to manufacturers and sellers. To monitor the implementation of law be entrusted to Roskomnadzor. How has this come? For me personally this news is not very surprising (and not only because this is another project state silly the Duma), not so long ago there was another similar initiative, the essence of which was to translate public transport to use the system "To the end of the year practically the whole of Moscow is covered
