LAISR

Government airborne ISR missions demanding higher throughputs now benefit from multi-megabit data rates in L-band to low-profile, small form-factor terminals

In response to specific government requirements for cost-effective high-throughput beyond line-of-sight (BLOS) connectivity for small-aperture aero platforms, Inmarsat Government offers L-band Airborne Intelligence, Surveillance and Reconnaissance (LAISR) service.

LAISR is a high-data rate, end-to-end airborne communication solution, utilizing the Wideband Streaming L-band (WiSL) capability via Inmarsat’s redundant, worldwide space and ground networks through micro-antennas as small as 5 inches. Enabled through the LAISR Network Management System, the service provides dynamic beam switching and frequency allocation across 600 active narrow spot beams globally. The LAISR service operates on Inmarsat Government’s Multiprotocol Label Switching network, which is scalable, redundant, high-capacity and ready to meet unique requirements of government customers, and is managed 24/7 by U.S.-based, security-cleared operations and engineering team.

LAISR provides high speeds up to 10Mbps simplex Single Channel Per Carrier (SCPC) transmission channel for high-quality video and data unidirectional traffic from airborne platforms to Inmarsat Satellite Access Stations (SAS). The customer payload is uplinked by a high-gain aero antenna using the standard or extended L-band frequency. A second channel, using Inmarsat SwiftBroadband service provides full-time, two-way data communications to support the aircraft, its payload and the Monitor and Control of the simplex link/SCPC modem. Multiple terrestrial options provide traffic backhaul from the Inmarsat SAS to the customer’s specific destination, which can include ground control stations, operation centers and remote terminals anywhere worldwide.

A subscription-based managed service offering, LAISR enables transmission of high definition full-motion video and data from a variety of manned and unmanned aero platforms, resulting in full situational awareness for the government users.
