Table 1-1 GPSCard Pseudorange Differential Initialization Summary
Initialization - Reference Station
Differential mode of operation is established at the reference station through a two step process: fix position and
logging observation and correction data.

FIX POSITION

The reference station must initialize the precise position of its reference antenna phase centre (lat/lon/hgt). This is
accomplished by utilizing the GPSCard FIX POSITION command. The syntax is as follows:
