Question

regulatory standards for inertial navigation systems?

Answer 1

inertial navigation systems:

1. it is a device that uses computer ,motion sensors ,rotation sensors to continuously calculate by dead reckoning the position,and also the velocity of a moving object.
2. these are used on mobile robots, and on vehicles  as ships,air crafts ,submarines,guided missiles.
3. these systems suffer from integration drift ,small errors in measurement of acceleration ,so to avoid these the position must be periodically corrected by input from some other type of navigation system.
4. it can detect a change in its geographic position, a change in velocity .since it requires no external references in order as it is immune to jamming and deception.
5. the marketing prices used in these systems are so high as it is used in many objects ,but it is based on the environment in which they are used.
6. it should have a range of navigation of vertical position accuracy as 1.5m ,horizontal position accuracy as 0.8m ,velocity accuracy of 0.005m/s .
7. the sensors range for accelerometer is +_10g,gyroscopes is +_490 /s,pressure should be 10 to 120KPa.
