Six of the ground stations will be vehicle based (see image above left) and will by operated jointly by RAF and Army personnel (hence Army Cooperation 'AC' in squadron title). The aircraft are fitted with an extensive suite of military communication equipment, consisting of a satellite communication (SATCOM), VHF, UHF
and HF radios and provide high speed data links to airborne and ground forces. The Sentinel's radar operates in two modes, the Synthetic Aperature Radar (SAR) which uses powerful processing techniques to present photo-like imagery of ground targets and a Ground Moving Target Indication (GMTI) mode, which detects target movement in the air and on the ground. Compatible with the USAF's similar JSTARS system, it will provide commanders of forces deployed anywhere in the world with real-time data to enhance mission planning.
