2.1 Theory of Operation

The STINGR operates on the Globalstar LEO satellite network. LEO (Low Earth Orbit) means that there are a number of operates on the Globalstar LEO satellite network. LEO (Low Earth Orbit) means that there are a number of operates on the Globalstar LEO satellite network. LEO (Low Earth Orbit) means that there are a number of
satellites in low earth orbit that constantly orbit the planet and can communicate with Globalstar devices that are within
range of its current position.
Since the satellite position is constantly changing, simplex devices on the ground will transmit (with no knowledge of Since the satellite position is constantly changing, simplex devices on the ground will
any of the satellites locations) and the transmission
relay the message to the nearest satellite gateway as shown below. Once received by the
message will be delivered to the simplex gateway where redundant messages are discarded and the data from the
message is sent to the OEM via the Internet. message is sent to the OEM via the Internet.
