1
Receiver will operate normally to –40 °C. Bluetooth module and internal batteries are rated to –20 °C.
2
The availability of the L2C code GPS signal is dependent on the US government.
3
Accuracy and reliability may be subject to anomalies such as multipath, obstructions, satellite geometry, and
atmospheric conditions. Always follow recommended practices.
4
Depends on WAAS/EGNOS/MSAS system performance.
5
May be affected by atmospheric conditions, signal multipath, and satellite geometry. Initialization reliability is
continuously monitored to ensure highest quality.
