Space Based Augmentation Systems Thales has been involved with Satellite Based Augmentation Systems for many years.
Users vary from oil exploration, sub-sea engineering and aviation.
SkyFix technology has been developed by Thales over the last 10 years. The selection, installation and maintenance of reference stations have been successfully managed by Thales and this experience has been used to develop other applications such as NEST Bed. Data is sent to the Master Control Centre at NATS Gatwick Services Management Centre for processing. NEST Bed was deployed and commissioned during summer 1998 and flight tests were successfully demonstrated at the September 1998 Farnborough Air Show where approaches were flown to Boscombe Down. For all the demonstrations the DERA BAC-111 aircraft was used for measuring and collecting approach and landing data which was demonstrated to have sufficient accuracy to meet Instrument approach and landing criteria.
