a. 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.
b. Acquisition sensitivity is the lowest GNSS signal level for which the device can still detect an
in-view satellite 50% of the time.
