We use voice commands to take care of duties that normally require numerous inputs on a keypad, such as punching in navigationcoordinates and changing radio frequencies and bingo fuel amounts.
GPS satellite position calculation is the key link of GPS navigation and positioning, calculating satellite coordinates quickly and accurately is important to improve positioning speed and precision.
This paper introduces the navigation principle of the SINS firstly, the navigation algorithm on geographical coordinates is deduced, and then the simulation program is developed.
