Abstract:	Honeywell and its teammates, Allied Signal and Trim- ble, have developed a design for a compact (100 it?) integrated Global Positioning System/Inertial Navigation System (GPWINS) under the GPS Guidance Package (GGP) Program funded by DARPA. This effort included developing new inertial sensor technology and imple- menting inertial aiding of the GPS receiver’s tracking loops. The inertial sensors consist of fiber-optic gyro- scopes and solid-state silicon accelerometers suitable for a I-nmi/hr-class navigation system. Inertial aiding of the GPS receiver’s carrier tracking loop was used to enhance tracking under severe dynamics without compromising anti-jam performance. This paper reviews the hardware and software architec- ture, packaging approach, and test results from a proto- type unit. These tests demonstrated the capabilities of the overall system, including integrated GPS/INS navi- gation and enhanced performance of the GPS receiver as a result of carrier loop aiding.
