5.2 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 GR-213 by using Differential GPS (DGPS)
real-time pseudo-range correction data in RTCM SC-104 format, with message types 1,2, or 9. As using
DGPS receiver with different communication parameters, GR-213 may decode the data correctly to generate
accurate messages and save them in battery-back SRAM for later computing.
