NavChip™

Bringing tactical grade IMU performance to an OEM chip form factor, NavChip now allows small platforms to achieve capabilities previously unobtainable.  Image stabilization is improved by the sensor's low angle random walk.  Navigation during GPS occlusion (coasting) is enhanced by the sensor's bias in-run stability.

Key Features

• LCC footprint incorporating castellated contacts for OEM integration
• Gyro bias in-run stability of 10 °/hr
• Angle random walk of 0.18 °/√hr
• Size 24.0 x 13.5 x 9.1 mm
• Weight 6 g
• Power 65 mA @ 3.25 V (211 mW) 
• Factory calibration and temperature compensation over -40 °C to +85 °C
• Packaged for environmental ruggedness and long term stability

NavChip Developer Kit

InterSense offers a NavChip Developer Kit which includes an interface board with the NavChip, a calibration/evaluation cube, a USB & RS-232 serial cable and all necessary software and documentation for evaluation and system integration. Additional NavChips can be purchased with the development kit.
