The Long Test Track (LTT) facility at MOD Pendine, suitable for high-speed dynamic trials, is unique to the UK. It has been used to test impacting probes for use in planetary exploration. It is a 1,500m instrumented test track, enabling trials of systems up to Mach 3, with accelerations of up to 130g. Pendine also has a Short Test Track of 200m. This can accommodate weights and velocities between 45kg at 500 m/s to 250kg at 250 m/s. This is an LTPA facility so MOD permission must be sought by third parties who wish to use the facility.
