HS-GPS is an intelligent switch for tracking devices, with an integrated Orbcomm Modem. Depending on the terrestrial network status (GSM / GPRS or other cell network) of the tracking
device, HS-SAT manages connections to the Orbcomm network and sends messages through it,
typically—but not limited to—geographical coordinates. As soon as coverage from terrestrial
network is regained, it simply disconnects from Orbcomm network and stops sending data
through it.
