Note: The above results are for GPS / BeiDou dual-mode working mode.
[Test condition 1]: The number of receiving satellites is greater than 6, the signal strength of all satellites is -130dBm, the
average value is 10 times, and the positioning error is 10 meters.
[Test condition 2]: The noise figure of the external LNA is 0.8, the number of receiving satellites is greater than 6, and
the received signal strength value is locked or not lost within five minutes.
[Test condition 3]: Open and unobstructed environment, continuous power-on test for 24 hours, 50% CEP.
[Test condition 4]: The number of receiving satellites is greater than 6, and the signal strength of all satellites is
-130dBm.
