Six-axis inertial measurement unit sports low drift, +/- 16 g acceleration range

Thales announces at Sensors Expo 2018, the availability of its NavChip2, the latest in its family of high precision Inertial Measurement Units (IMUs). The NavChip2 provides the highest performance to price in the market of 6-axis IMU’s and is fully factory calibrated.  Embedded temperature sensors enable excellent compensation over the entire -40 °C to +85 °C temperature range. MEMS sensor technology, propriety advanced sensor fusion processing techniques, a small and easily mountable package and low power dissipation make this IMU ideally suited for applications including drone navigation, robotic control, camera/antenna platform stabilization and augmented/virtual reality.   

The NavChip2 achieves a level of performance, miniaturization and environmental ruggedness superior to competing IMUs while maintaining an affordable price point. The NavChip2 is a very low drift IMU with a full-scale acceleration range of +/- 16 g and a full scale angular rate of 2,000 degrees/sec.  Typical specifications include a gyro bias in-run stability of 5 , angular random walk of 0.18 , velocity random walk of 0.03  and an exceptionally quiet acceleration noise performance of better than 83 .  Its miniature package of less than 2.0 cm³ (12.5 x 24.5 x 5.4 mm) and weight of 3 g allows for flexible integration.  Power consumption is a low 135 mW, making it ideally suited for power-sensitive remote and battery-operated systems.

 Multiple output interfaces, including TTL UART or SPI-compatible provide the designer with exceptional flexibility.  The external sync pin can accept optional GPS pulse-per-second or faster synchronization signals.  Single supply operation is from 3.25V to 5.5 V.

The NavChip2 is available as a discrete component with snap-fit connector. The NavChip2 unit price is $450 in small quantities.   Evaluation units are available from stock.
