GP2000 – GPS CHIPSET DESIGNER’S GUIDE
STATIC NAVIGATION
The GPS Architect Global Positioning Development System
has been developed from GPS Builder-2, a PC-based GPS
development system (no longer available). Two GPS Builder-2
systems have been tested side-by-side to illustrate the improved
accuracy in position fixes that results from using a 12-channel
receiver rather than a 4-channel receiver.
Fig. 27 shows a GPS Builder-2 position fix scatter plot where
10 satellites are included in the solution. Fig. 28 shows position
fixes over the same period but for a GPS Builder-2 system using
only the ‘best’ 4 satellites. A comparison of these plots clearly
demonstrates the benefit to position fix accuracy of ‘all-in-view’
used by GPS Architect.
Fig. 29 shows the sort of position fix accuracy that can be
achieved when S/A is inactive (no DGPS corrections applied).
Fig. 30 shows the number of satellites tracked during this period.
