Page History

The same inertial reference systems are installed permanently on Polar 5 and Polar 6.

An inertial ravigation system (IRS) is a navigation device that uses a computer, motion sensors (accelerometers) and rotation sensors (gyroscopes) to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references.

Sensor-Info: aircraft:bt-67:ins, 6284

|| Dimension (L x W x H)| 165 x  163 x 163 mm ||
|| Weight | 4.5 kg||
|| Power Supply| 22 - 30 VDC ||
|| Data interface | ARINC 429||

During flight INS data are stored within the aircraft onboard DMS system.

After the flight INS data are accessible via the land system of the aircraft data managment system (DMS).
