NavCom RT-3020 Rev.F - Manual (Page 21)

RT-3020 User Guide – Rev. F
RS-232 serial ports with less than 20ms latency.
<1cm horizontal and <2cm 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.
The system resolves ambiguities at startup or on
satellite reacquisition typically within 2 seconds.
The standard output data rates for the RT-3020M
only are <25Hz for proprietary raw data and <10Hz
for PVT data.
NCT Binary Proprietary Data
The sensor can output proprietary raw data
containing information including (but not limited to):
9 Satellite Ephemeris (0x81)
9 Satellite Almanac (0x44)
9 Raw Pseudorange Measurements (0xB0)
9 Position, Height, & Time (0xB1)
9 Velocity & Heading (0xB1)
9 Signal to Noise (0x86)
9 Channel Status (0x86)
9 Correction Data (mirror data; 0xEC)
9 Event/Marker (M model only; 0xB4)
9 Measurement Quality (0xB1 and 0xB5)
These data can be integrated in real-time positioning
applications or post-processed against any number of
software applications designed to handle NCT or
RINEX raw data. A Technical Reference Manual is
available on NavCom’s web site, which describes the
attributes of each of the input/output records (see
Related Documents in the fore-matter).
