Notes:

SPARTAN is a highly accurate, flight proven automatic navigation and terrain following system to enable low level covert operations. The system reduces cockpit workload and greatly improves mission effectiveness.
Under development for over a decade and extensively flight trialled on a variety of low level aircraft, including Tornado, A6E Intruder and F16 AFTI, SPARTAN was selected by the Ministry of Defence (UK) for the RAF's Tornado mid-life update.
The elevation profile of the terrain overflown is measured by a series of covert radar altimeter samples. This profile is compared with an on- board digital terrain database to provide rapid and continuous position fixes Once an accurate navigational position has been achieved,
SPARTAN 'looks ahead' in the database and calculates a mission optimised terrain
following flight path, which can be followed either manually, using the pilot's flight director, or automatically via the aircraft autopilot
