Inmarsat Government has successfully completed customer airborne testing of its new L-band airborne intelligence, surveillance, and reconnaissance (LAISR) service.

The LAISR service is designed to address the high-speed, beyond line-of-sight (BLOS) connectivity requirements of airborne intelligence, surveillance and reconnaissance (AISR) missions worldwide. It will also provide guaranteed L-band data transmission rates up to 10Mbps.

Specifically, the service could be used for electro-optical and infrared, real-time high-definition video streaming, laser range finder and designator transmission, support of signals intelligence applications and synthetic aperture radar applications, unmanned aerial systems, as well as backup command and control.

Inmarsat Government President and CEO Susan Miller said: "LAISR is a game-changing satcom service for AISR.

"LAISR is a game-changing satcom service for AISR."

"It has multiple benefits and applications that are unmatched in the industry, and will operate on Inmarsat’s advanced Alphasat L-band satellite, covering Europe, the Middle East and Africa, with further plans to operate globally on Inmarsat’s extended L-band fleet."

LAISR uses an integrated terminal that offers a simplex broadband return link to support AISR mission requirements and a full duplex channel for command and control. It provides military and intelligence community with full situational awareness by enabling transmission of high-definition full-motion video and data from varied manned and unmanned aircraft.

Operation in L-band ensures the highest availability of service allowing aircraft to fly over urban, mountain and jungle environments, at low altitudes, in cloud cover and in dense rain.

The satcom link free-up additional assets for AISR missions by providing an alternative communication path to mitigate electronic attack and also eliminates the requirement for a communications relay payload or retransmission vehicles.

The link is easily added to current platforms supporting Inmarsat SwiftBroadband service. It provides up to 10Mbps simplex single channel per carrier transmission for high-quality video and data unidirectional traffic from airborne platforms to the Inmarsat Satellite Access Station.

The service is scheduled to be made available for US Government customers by June this year.
