GLOBALSTAR SATELLITE NETWORK
The network is a Low Earth Orbit (LEO) satellite constellation with
the satellites constantly orbiting the earth and completing their
respective orbit in less than 2 hours. Because of this, the SmartOne
will be in contact with at least one of the satellites during each
scheduled transmission. In LEO communication networks, the
satellites are constantly changing their positions in the sky relative
to the transmitter on earth. This minimized the shading effects seen
in geostationary satellite systems where the mobile device must be
pointed toward a specific direction in the sky. Geostationary satellites
also orbit at a much higher altitude and move along the equator.
Messages are transmitted from the SmartOne via the Globalstar
Satellite Network using an uplink-only connection (one-way data transmission) and received by a Globalstar Ground
Station. The messages are then sent via an HTTP or FTP server to the Internet and received by the VAR or end
customer’s back office application and converted into actionable data.
The SmartOne will send each message 3 times to ensure that the message has been received by the Globalstar
Satellite Constellation. Once Globalstar receives the message, any remaining duplicate messages are ignored and
discarded (VAR or end user account is only charged for 1 transmission).
