Note: The above results are GPS/Beidou dual-mode working mode; the highest altitude can reach 18,000 meters, but the
accuracy of the data will be deviated after more than 10,000 meters.
[Test condition 1]: The number of receiving satellites is greater than 6, the signal strength of all satellites is -130dBm, the
average value is obtained for 10 tests, and the positioning error is within 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 under the condition of locking within five minutes or not losing the lock.
[Test condition 3]: Open and unobstructed environment, 24 hours of continuous power-on test, 50% CEP.
[Test condition 4]: The number of receiving satellites is greater than 6, and the signal strength of all satellites is -130dBm.
