Sensor GNSS RF Sensitivity Test (ARM)

A GPS device and antenna should have an Over the Air (OTA) acquisition sensitivity of -142 dB or better. For OTA tracking sensitivity, it should be better than -145 dB.

Interference with other components in the system should not cause degradation from these sensitivity goals. Display, Camera, other radios, such as NFC, Bluetooth, WiFi, and Mobile Broadband, are some of the potential components which can cause interference. Active usage of such components shall not degrade GPS RF sensitivity.

Human hands holding the device one of the common positions should not degrade GPS RF Sensitivity. Device shall be able to maintain OTA acquisition sensitivity at -142 dBm and OTA tracking sensitivity of -145 dBm when the system is held in common positions.
