… which will not replace the other means of Communications
Because you need a satellite Because satellite resources could be limited Because you ‘normally’ need to be at periscope depth to transmit
or receive data Because some countries have interest in areas not covered by the
GEO satellite constellations
Areas where Thales’s solutions could make the life of submariners easier

What about Polar Areas ?
GEO satellite constellations do not cover polar areas Communications are impossible
at latitude above 80°
The reliability of the communication links at latitude above 70° is not always guaranteed for mobile users
Some countries are considering the use of Polar HEO satellites to offer 24/7 reliable High Data rate communications in X and Ka-band
Combining a 3-axis architecture and Ephemeris Tracking capability, DIVESAT is compatible with GEO and Polar HEO and shortens the duration of communications

… And the SATCOM Indiscretion ?
In standard configurations subs require to be at periscope depth to establish SHF SATCOM links SHF signals do not travel through sea
water
SATCOM terminal is located on the top of one of the sub communication mast
RTOF, DIVESAT mounted on a recoverable buoy, Gives submarines the possibility to
transmit and receive at depth
Enables communications of longer duration while the submarine remains safe
