C-Nav2050 User Guide
C-Nav2050R
This model is the same as the M model, except that it is
designed for vehicle mounting with separate antennas
for GPS/SBAS (WAAS, EGNOS, MSAS, GAGAN) (P/N:
8250001-0) and C-Nav Corrections Service Signals
(P/N: 825R003-0). The purpose of the separate antenna
systems is to provide better low-elevation satellite
detection to C-Nav Correction Service signals in high-
latitude locations.
The GPS antenna port provides 4.3VDC
and the C-Nav antenna port provides
5.0VDC. Care must be taken to select an
appropriately rated GPS antenna if the
standard C-Nav antenna is not used.
Features That Apply to All Models
(C-Nav2050G, C-Nav2050M, C-Nav2050R)
Output Data Rate
All C-Nav2050 models can output proprietary raw data
at programmable rates from <1Hz to predetermined
rates up to 50Hz and Position Velocity Time (PVT) data
at programmable rates from <1Hz to predetermined
rates up to 25Hz. This is accomplished through two
115kbps RS-232 serial ports with less than 20ms
latency. <10cm horizontal and <15cm vertical accuracy
are maintained as each output is independently
calculated based on an actual GPS position
measurement, as opposed to an
extrapolation/interpolation between 1Hz measurements.
