GLONASS will catch up on GPS accuracy by 2015
Specialists of the General Staff of the Russian Federation expect that the Russian system of global GLONASS will catch up with GPS in accuracy by 2015. This will happen thanks to the space geodetic system being developed in Russia, said the head of the military topographical department of the General Staff of the Russian Armed Forces (VTU GS Armed Forces) Rear Admiral Sergei Kozlov.
The Russian space geodetic system will consist of three segments: ground observation, control and information processing points (the first segment), a high-orbit constellation of GLONASS satellites (the second segment) and the third - the segment that is missing so far between them - two Geo-IK-2 geodetic instruments on solar synchronous orbit with an altitude of about 1000 km.
The SKA Geo-IK-2 is equipped with a high-precision Sadko altimeter manufactured by Thales Alenia Space (France) and satellite navigation equipment designed for measurements via the SKA-BKA line. The presence of the measuring line SKA-VKA is a fundamentally new element, due to which the accuracy of the readings of the GLONASS system will be significantly improved.
The launch of the SKA Geo-IK-2 is carried out by specialists of the military topographic department of the General Staff of the Russian Federation at the expense of the budget of the Ministry of Defense. These costs are spelled out in a separate line in the Federal Target Program “Global Navigation System (2011-2020)”.

The first of the two satellites, Geo-IK-2, was launched on February 1, 2011, but failed: due to errors in the operation of the upper stage, instead of a circular orbit of 1000 km, the device entered an elliptical orbit with an altitude of 369 to 1021 km. They wanted to transfer the satellite to the calculated orbit, but this did not have enough fuel. A month after launch, the connection with the satellite was lost .
