Radical Streamlining of GPS/INS

James L. Farrell

Abstract:	ExteneWalterationofexistingintegratedsystemdesign offers major ben@ts in performance and economy. DuringGPS-available periods,estimationof dynamics from carrier phase triple differences can relieve the burdenof ambiguityresolution(duringperiodsof GPS unavailability,free-inertial coast is prescribedwith no change). Byplaang emphasisappropriatelyon short-termbehavior, compulhgrequkementsare significantly reducedwithnumerousalgotimic enhancementsnot at all incommonusage. Variousappliitiondependent akemdve formulationsare offered,withimpksdionson intdace standardsforbothiruwlialand GPS data. This work is the basis for near-future van and fliiht tests usinga low-costIMU.
