is anyone here knowledgeable about the integration of GPS and INS(inertial navigation systems)?

Question

We are college students in the Philippines currently taking up electronics and communications engineering. Our thesis is about "PC-Based Real-Time Vehicle Tracking using GPS-Aided Inertial Navigation System". We totally have no background on this topic. Your help would be very much appreciated. Thanks

Answer 1

ultimately, the accuracy of the tracking is limited by the GPS. The advantage of GPS is its basic accuracy is time independent. Without special correction, it should be able to give you about 10 meter resolution at any time. the ins can give much finer resolution, but its errors accumulate with time, so at the end of the day, your tracking position could be off by several kilometers. Periodic GPS measurement gives a method to correct the accumulative ins data errors.
