ZDA Data Format
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 CF card receiver by using
Differential GPS (DGPS) real-time pseudo-range correction data in
RTCM SC-104 format, with message type 1,5 or 9. As using DGPS
receiver with different communication parameters, GPS CF card receiver
may decode the data correctly to generate accurate messages and save
them in battery
–
back SRAM for later computing.
