By default, SM Pro is shipped with a passive GPS antenna. Due to interference issues from USB 3.0 devices and other sources, the satellite signal may not be sufficient to obtain a GPS lock. An active antenna can be used to overcome this limitation. SM PRO hardware board revision PRO-3 or later provides support for external active GPS antennas. You can find your board hardware revision in the device tab.

Place the antenna at least 50 cm away from SM Pro. In StellarMate App, tap the GPS status indicator to toggle between the Passive & GPS antennas.

GPS status is displayed in the StellarMate Pro App Power tab.
