Can GSM trackers be configured to reply only when telephoned for GPS location?
I have read that some will update position in realtime. For this feature, I would think the tracker would need to constantly transmit data to a cell site. Has anyone experienced RFI to their multi-rotor using one of these trackers configured to update in realtime?
I would only like to poll it for location if I lost it or had a 'flyaway'.
