Globalstar Satellite Network
The network consists of 32 Low Earth Orbiting (LEO)
satellites that are constantly orbiting the earth and
complete their orbits in less than two 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 three times to insure 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 one transmission).
