10 Test Bed Receiver Subsystem Addendum – Rev 1
Single Frequency GPS GLONASS
The GPS GLONASS is configured to track 12 L1 C/A-code signals (Narrow Correlator tracking technology), and 6 L1
GLONASS C/A-code signals. The output is used to compute ionospheric corrections.
Dual Frequency GPS GEO
Within the GPS GEO group, up to 2 channels can be configured to track L1 C/A code GEOs
The L1 C/A code and L2 C/A code measurements are used to derive ionospheric corrections.
Other Outputs & Inputs
• A 10 MHz output is available for use with an internal clock.
• Two serial ports provide: - raw satellite measurements (pseudorange, carrier & time)
- receiver status data (communications & tracking)
- raw satellite data (ephemeris & almanac)
- fast code corrections for signal stability monitoring
• The receiver accepts an external input from a 10MHz atomic clock or its internal OCXO for synchronization.
