Description

This system, the INS-DM, is an IP68 rated version of an all-new generation of super ruggedized, shielded from the EMC/EMI, fully-integrated, combined Inertial Navigation System (INS) + Attitude & Heading Reference System (AHRS) + Air Data Computer (ADC) high-performance strapdown system, that determines position, velocity and absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted. Horizontal and Vertical Position, Velocity and Orientation are determined with high accuracy for both motionless and dynamic applications.

The Inertial Labs INS-DM can support multiple types of MEMS Inertial Measurement Units (IMU) developed by Inertial Labs. Additionally, the INS-DM supports other IMU’s, like the Honeywell HG4930. The INS-DM also utilizes different multi constellation (GPS, GLONASS, GALILEO, QZSS and BEIDOU) GNSS receivers like Novatel OEM7 series or the u-blox F9 series.

The design of the INS-DM also includes an optional Air Data Computer (ADC), supported by two Honeywell barometric sensors, and the ability to support an internal Fluxgate or external Stand-Alone Magnetic Compass (SAMC). The INS-DM contains Inertial Labs new on-board sensor fusion filter, state of the art navigation and guidance algorithms, and calibration software.
