British Aerospace Systems and Equipment (BASE) are providers of a SNU 84-1 type INS for various aircraft platforms. The EH101 Merlin application, in particular, includes an integral Air Align mode, allowing full alignment of the INS in flight, using Doppler radar. This variant of the INS has been the subject of extensive flight testing in EH101, and has demonstrated full alignment over land and sea. The Air Align mode features a Doppler/INS Kalman filter used in feed-back configuration. This configuration was chosen, because of the paramount need to align in flight. The INS has been successfully tested in the adverse vibration environment of a helicopter. This includes Ground Align, with the rotor turning. Some details of filter development and trials results are given. More recently a GPS/INS filter has been developed and subjected to flight trials in the UK Royal Air Force 'ARIES' Comet flights. This filter enables full in-flight alignment to occur, equivalent in accuracy to a ground align.
