SARBE 8 is designed to provide a multi-role beacon capability within a single unit. Intended primarily for Military users, the SARBE 8 operates as both a standard RESCUE beacon and a COMBAT SURVIVOR RECOVERY beacon. A wide range of operational and power management features are available via the PC based programming system.

In all modes of operation SARBE 8 may be programmed to operate on automatic or manual update of position co-ordinates. In manual update mode the GPS receiver will operate until a 'GOOD' position fix is obtained. The GPS receiver then powers down and the position co-ordinates are stored and transmitted each time a data transmission is called for. The position co-ordinates may be updated at any time by operating the 'Self Test' lever. In automatic mode, the GPS receiver powers up every 20 minutes to acquire a new position co-ordinate.

On activation, SARBE 8 transmits a conventional COSPAS/SARSAT compatible swept tone signal simultaneously on 121.5 MHz and 243 MHz. This is interspaced at 5 second intervals with a data burst containing the USER IDENTITY (User Programmable) and the Latitude and Longitude position of the beacon.

The data transmission enables any rescue aircraft carrying the SARFIND decoder unti to precisely determine the location of the beacon and fly directly to it. Rescue aircraft not carrying the SARFIND are able to locate the beacon using conventional search and rescue direction finding techniques and equipment. Voice communication is provided for final 'Talk Down' and survivor confidence.
