M2M Connectivity supply complete integrated modems for satellite tracking with GPS and satellite communications.
We have modems for Globalstar Simplex, Orbcomm 2-way messaging, and Iridium SBD. (Short Burst Data).

Some satellite trackers include integrated long-life batteries for many years of operation, others are 2-way communication devices. These are ideal for developers and system integrators needing a not too complex solution for tracking of vehicles/assets in remote locations.
