Compute speed?

[RicardoDominguez]

How accurate will it be?

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

[RutwikZapake]

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
