Checksum

(1) SiRF Technology Inc. does not support magnetic declination. All "course over

ground" data are geodetic WGS84 directions.

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 AQ-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, AQ-300 may decode the data correctly to

generate accurate messages and save them in battery-back SRAM for

later computing.
