Communication
Each glider is equipped with two bi-directional
communication links, located in the tail.
FREEWAVE A high frequency radio (RF)
communication link (Freewave Technologies) allows
for high speed, line of sight data transmission
and a repeater can be used to increase the
distances of communication IRIDIUM Satellite
telephone link (Iridium Satellite LLC) also
provides global communication coverage.
ARGOS ARGOS transmitter is also located in the
tail and broadcasts GPS coordinates to locate the
glider in case of an emergency.
-CAN WE GET THE SHIP GPS POSITIONS?

-We are very interested in combining this data
with the ship discrete measurements to develop
new products.

Future steps? Flight Smart Automated
-Using agent oriented programming make Glider
fleets smart by optimizing on their sampling
based on what data is delivered from the
observatory.
