Description: On the basis of the software GPS receiver and SINS assisted GPS tracking technology, ultra-compact combination of an SINS/GPS navigation scheme. The Super Compact program was added in the capture of the GPS receiver software link based the phase estimate Narrow capture algorithm, thereby improving the accuracy of frequency acquisition, frequency tracking traction process is omitted signal tracking link SINS position, speed information and satellite parameters, to strike a radial distance between the receiver and satellite and the radial distance rate, to provide auxiliary code loop, carrier loop and thereby reducing the influence of the carrier dynamic changes of the tracking loop, and to improve the dynamic tracking of the tracking loop performance while reducing the noise bandwidth of the carrier loop, to reduce the code ring associated interval, thereby improving the accuracy of the tracking of the carrier ring and the code ring.
