Ultra-tight navigation system is a GPS-based navigation system which fuses inertial sensors information with GPS signals form satellites to finding more accurate positioning information and reject Dynamic Stress. ... The first one, Global positioning System (GPS), employed satellites signals to recover the position of a target. ... The second one, navigation system with inertial sensors which includes rate gyroscope and accelerometer is used in navigation before employing GPS systems. ... Navigation system with this information and knowledge of one reference point position, finds the place of moving abject. This system offer more accurate results in short time than GPS receiver, but in long term suffers from measurements noise in sensors which increase with time even in expensive ones, also its performance is related to accuracy of reference position.
