摘要：Techniques for loosely coupling a Global Navigation Satellite System (“GNSS”)
and an Inertial Navigation System (“INS”) integration are disclosed herein. A system
includes a GNSS receiver, an INS, and an integration filter coupled to the GNSS receiver
and the INS. The GNSS receiver is configured to provide GNSS navigation information
comprising GNSS receiver position and/or velocity estimates. The INS is configured to
provide INS navigation information based on an inertial sensor output. The integration
filter is configured to provide blended position information comprising a blended
position estimate and/or a blended velocity estimate by combining the GNSS navigation
information and the INS navigation information, and to estimate and compensate at least
one of a speed scale-factor and a heading bias of the INS navigation information.
