Note: The above results are for GPS/Beidou dual-mode working mode; the maximum altitude can reach 18,000 meters, but the accuracy of the data will be biased after exceeding 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 taken after 10 tests, and the positioning error is less than 10 meters.
[Test Condition 2]: The external LNA has a noise coefficient of 0.8, the number of receiving satellites is greater than 6, and the received signal strength value is locked within five minutes or does not lose 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.
