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-6021-X6 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-6021-X6 may decode the data correctly to
generate accurate messages and save them in battery-back SRAM for later computing.
