Collaboration with GPS/LORAN and INS
Takao sagawa
Tamotsu ikeda
(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(?)
