How accurate will it be?

Do we need it? Do we want it in conjunction with something else?

For the module we are using, following are the accuracy details: Horizontal accuracy: -GPS: 2.5m -SBAS: 2.0m, SBAS= satellite based augmentation system -SBAS+PPP: <1m(2D, R50), PPP= precise point positining -SBAS+PPP: <2m(3D, R50)

Accuracy for Timepulse signal: -RMS: 30ns -99%: <60ns -Granularity: 21ns -Compensated: 15ns

Velocity Accuracy: 0.1m/s Heading accuracy: 0.5 degrees
