(Position、 timing and Attitude Sensor 　ＶＳＡＳ－２ＧＭ )

１． INS is self-directed system not to need external

signals.

2. INS keep to output position, velocity, bearing and

pitch, roll and yaw attitude.

3. INS is not able to keep position accuracy for long

hours caused by drift error.

4. INS is big and very expensive.

What is inertial navigation system ?

Dialog of modern sensor

sensor

GPS ANT

The sensor integrates GPS with inertial measurement sensor, which uses GPS to achieve meter accuracies and to shorten alignment time.

Merit of modern sensor

1. High performances2. Small size3. Low weight4. Cost-effective and5. In-door navigation by

GPS/e-LORAN（？）
