Abstract The work provided in this thesis dealt with comprehensive evaluation of performance of a proposed GPS/INS/Map integration for Land Vehicle Navigation System. The motivation behind utilizing an integrated system for LVNS is that Land vehicle navigation is primarily dependent upon GPS which provides accurate positioning and navigation capabilities in ideal conditions under open sky environment. This situation sometimes changes dramatically in urban and rural canyons where GPS accuracy degrades, and in some cases, to an extent that it is no longer reliable, and thus continuous positioning is not possible through system based only on GPS. So, GPS/INS/Digital Map Integration algorithm was provided to impose constraints on navigation solution by using Kalman filter estimation to combine the three navigation systems |
