WebDec 16, 2006 · Traditionally GPS and INS are coupled through a Kalman filter for the processing of raw measurements to obtain position, velocity and time. Initially, two broad classes of integration; loose and tight coupling were developed. However, in recent years a third class has emerged, referred to as deep integration or ultra-tight integration (Gautier ... WebHowever, loose coupling provides a more continuous solution with respect to the tight strategy. The first strategy is able to provide navigation solution, also in the case of a complete GNSS outage. Under such conditions, the position estimated coincides with the pseudolite-only solution.
WebNov 1, 2024 · For the ultra-tight integration of GNSS and MEMS IMU with federated architecture, the NCOs in each channel should be controlled by the navigation solutions associating with the channel pre-filter outputs. However, with such NCO control strategy, the navigation solution derivation errors will be significantly different from the signal tracking ...
