Abstract (en)
[origin: WO0146712A1] The invention concerns the hybridization of an inertial unit and a satellite positioning receiver in order to correct the long-term drift of the inertial unit. There are two known types of hybridization, one called loose and the other one called tight . Loose hybridization has the disadvantage of requiring complete measurements from the positioning receiver but it does not involve the use of sensitive data from the positioning receiver. Tight hybridization operates even with a positioning receiver supplying incomplete data but requires the use of sensitive data from the positioning receiver. The invention provides a hybridization halfway between loose hybridization and tight hybridization having the advantages of both but without their drawbacks.
