1. Tracking sensitivity is the lowest GNSS signal level for which the device can still detect an
in-view satellite 50% of the time when in sequential tracking mode.
2. Acquisition sensitivity is the lowest GNSS signal level for which the device can still detect
an in-view satellite 50% of the time.
Operational limits
Altitude <6000 m or velocity <100 m/s
(Either limit may be exceeded, but not both.)
