New Antarctic antenna GLONASS and the status of the navigation system

[Antarctica]on Monday (the day before) the head of Roshydromet (Alexander Frolov) has declared to journalists that in February (about a month ago) at Novolazarevskaya station (Antarctica, on the right in the photo) has been installed (Roscosmos) special antenna, which will allow you to adjust the operation of the satellites of the Russian GLONASS satellite navigation system and improve its accuracy. He also explained that Russia could not see all satellites, and this antenna will allow you to track those spacecraft that are visible only in the Western hemisphere.

RIA Novosti, posting words Frolov, added that in 2010 the orbital grouping of the GLONASS system is planned to be increased to full strength (24 satellites), as well as create the necessary reserve of the spacecraft.

Take a look at official data on the composition of the group (in the case of garraffello will fit the duplicate Coral CDN or peeep-the cast). You will see immediately that the planned actions are executed: in the third orbital plane two satellites sent into orbit reserve spacecraft, their place remains vacant for a while. New satellites, three launched from Baikonur in early March, is also intended to take their places on that plane; thus, after a few weeks the third plane of the GLONASS will be not just filled to the brim with satellites, but with the necessary reserve vehicles.

But now on the third plane lacks three consecutive working satellites: the former withdrawn into reserve, and a new one commissioned. This shortage leads to the fact that in most of the world navigation signal GLONASS available no more than 80% -90% of the time during the day.

Here's how it looks on a map:

It is nice to know it's not too long before.

Why I left Google Zurich

the Backstory The question I often hear from different people and now I will try to answer it. Probably for anybody not a secret, but still: how does Google? They recruit the best engineers pay them large enough (even for Switzerland) salary and create an amazing environment for work, free food, massage at the office, the phantasmagoric recreation area , childrens slide down directly into the dining room, etc. This is very cool, like to write journalists, but it doesn't matter. Well, how many times will you walk down the hall on the hill and is it important? Free food has led to the fact that the majority of Googlers fat pounds five after a job, thus denying yourself the pleasure to go to lunch every day in a new restaurant. What's more determines how good you feel at work, free food, massage, design zones, the rest or the work that you do? I'm sure that's really important what you do every day and how this activity brings joy. Google hires the b

New web-interface for statistics and listen to the calls for IP PBX Asterisk

the Idea of writing web-interface for statistics and listen to the calls for IP PBX Asterisk is not left me for several years now. The solutions found in Internet, are not satisfied on certain criteria — somewhere lacked functionality, some of them are not pleasing to the eye. And so, armed with technology stack and riding warhorse provided by ServerClub I went. The result of my journey has become a new interface , with charts, graphs and the ability to download and listen to the calls. I will not further bore you with words, here are a couple of screenshots: And under the cut are waiting for you a video guide on the interface, necessary settings and detailed description of the available functionality. the Interface.
