Launching at RoboBusiness 2019 in Santa Clara, CA, Thales Visionix’s NavChip Series 3 embarks as the company’s latest family of high precision Inertial Measurement Units (IMUs). The micro electromechanical systems (MEMS) devices feature proprietary signal processing capabilities for demanding applications. Users can choose the optimum performance at their selected price point from both NavChip and NavChip Series 3 Class A and Class B parts.

The logic behind NavChip Series 3 Class A and Class B IMUs is to increase the performance accuracy of a distinct parameter:

  • Class A bias in-run stability to 4º/hr. (typical), 5º/hr. (max.) with an output rate of 1 kHz
  • Class B bias in-run stability 5º/hr. (typical), 10º/hr. (max.) with an output rate of 1 kHz

Other features include a ±16g operating range with other ranges available upon request, embedded Attitude and Heading Reference Systems (AHRS), the ability to accept external inputs such as a magnetometer, embedded temperature sensors, a full-scale angular rate of 2,000º/s, and an acceleration noise performance of better than 83 µg/√Hz.

NavChip Series 3 IMUs come in packages measuring 12.5 mm x 24.4 mm x 6.1 mm and weigh 3g allows. Power consumption is 135 mW while operating from a single supply of 3.25V to 5.5V.

Unit pricing for a 50º/hour gyro bias in-run stability device is $899 and a 100º/hour per hour gyro bias in-run stability device is $450. Evaluation kits for the IMUs cost $1,495 and $895, respectively. For more details, visit the NavChip family.
