(1) SiRF Technology Inc. does not support magnetic declination. All “course over ground” data are
geodetic WGS84 directions.
A.2 RTCM Received Data
The default communication parameters for DGPS Input are 9600 baud, 8 data bits, stop bit, and no parity.
Position accuracy of less than 5 meters can be achieved with the GPS-300 by using Differential GPS (DGPS)
real-time pseudo-range correction data in RTCM SC-104 format, with message types 1, 5, or 9. As using
DGPS receiver with different communication parameters, GPS-300 may decode the data correctly to generate
accurate messages and save them in battery-back SRAM for later computing.
