The proposed analytical algorithm provides good results when calculating positions of the GLONASS
satellites in the time-range of 30 minutes forward and 30 minutes backward from the given current state vector.
Although GPS system uses WGS84 (World Geodetic System 84) whereas GLONASS
uses PZ-90 (Parametry Zemli 1990) reference system, since 2007 ephemerides for these two satellite systems are expressed in current ITRS realization.
signals dPCC (IF combination) are slighty larger and range from 1 to -3 mm for the LEIAR25.R3 LEIT antenna, from 1 to -2 mm for the LEIAR25.R3 LEIT antenna and from 2 to -4 mm for the LEIAR25.R4 LEIT antenna, respectively.
The first overseas GLONASS
ground station for differential correction and monitoring was launched in Brazil in February 2013.
The follow-on GNS2000--with a 99-channel GPS WAAS and GLONASS
receiver--provides equally impressive battery life.
Rogozin said that the Glonass
satellite grouping currently comprises 24 operational satellites, which ensures its global coverage.
Global Positioning System, the Glonass
system allows users to pinpoint their location to within a few yards.
eCall and ERA Glonass
are planned for initial implementation after 2013, and is backed up by numerous car, truck and bus manufacturers and the European Automobile Manufacturers Association (ACEA).
According to earlier Russian media reports, during his last month's Moscow visit for the Joint Inter-governmental Commission on Military-Technical Cooperation, Defence Minister AK Antony had reached an agreement for receiving signals from GLONASS
military segment for precision guidance of Indian missiles and aircraft.
India's participation in GLONASS
is strategically significant.
Sunday's launch of the Proton-M carrier rocket was supposed to deliver satellites for the completion of Russia's Glonass
satellite navigation system.
