The GPS/GLONASS Navigation RECEIVER GL-NDV68E is a high end 24-channel GPS/GLONASS receiver provides continuous all-in-view navigation satellite tracking.
There are three modes of satellite tracking:
The Mode I is system-primary and automatically selected: receiver channels track all GLONASS satellites in view, the rest channels track GPS satellites.
Other modes are available upon pilot selection:
Mode II: tracking of all GLONASS satellites in view;
Mode III: tracking of all GPS satellites in view.
The digital receiver computes position, updates ten times a second, measures position to 15 meters RMS, and measures velocity to 0.1 m/s RMS.
Main processing functions, handled by the GL-NDV68E, include:
GPS position and velocity sensing
the Receiver Autonomous Integrity Monitoring (RAIM), required for Non Precision Approach, Terminal and En Route stages of flight; the Fault Detection and Exclusion Algorithms (FDE) detect and remove erroneous measurements, providing digital interfacing. GL-NDV68E can use real-time RTCM differential correction for GLONASS and GPS. Advanced signal-processing techniques, such as Differential GNSS and Kinematics Carrier-Phase Tracking will allow GNSS systems to be certified for Category (CAT) I, II Precision Approaches in the future.

3 More New Glonass Satellites Launched
The Russian Federal Space Agency (Roscosmos) successfully launched a Proton-M rocket and three GLONASS-M satellites at 10:53 a.m. (GMT) on December 25 from the Baikonur spaceport in Kazakhstan.
The spacecraft were placed into orbital plane 1 on the GLONASS constellation, where they will occupy slots 2, 3, and 8, according to the Roscosmos Information-Analytical Center. Built by Reshetnev Informational Satellite Systems, the modernized GLONASS space vehicles will join 17 operational satellites now in orbit. Newly launched GLONASS satellites are usually brought online within a month or so.
Changes in the GLONASS program this year mean that the full constellation in the future will have 30 satellites rather than 24, with each of three orbital planes will hosting eight nominal and two backup satellites.
The current GLONASS constellation provides 95 percent coverage of Russia territory and 83 percent global coverage, according to Roscosmos and Reshtenev, with each launch improving these values.
In 2007, Reshetnev doubled its production of GLONASS satellites, accomplished in part through introduction of computer-aided acquisition and logistics support technologies and 3-D computer design systems, representatives of the public company said.
By 2010, Russia will launch the first of its GLONASS-K series satellites, with four of these being checked out on orbit over the following two years. A new unpressurized design ensuring operation of the spacecraft systems in an outer space environment is expected to improve satellite survivability while reducing the size and weight of the SVs.
The smaller, lighter design will enable Roscosmos to launch two GLONASS-K satellites at a time on Soyuz-2 rockets rather than Protons, reducing the launch costs by half, according to Roscosmos.
