Inertial Labs INS-DH-OEM Dual Antenna GPS-Aided INS

Inertial Labs INS-DH-OEM Dual Antenna GPS-Aided INS

Manufacturer: | Categories: ,

The INS-DH-OEM from Inertial Labs utilizes an advanced dual antenna GNSS receiver and a Honeywell HG4930 IMU to provide accurate position, velocity, heading, pitch and roll of the device under measure. This product is well suited for applications such as flight control, remote sensing and photogrammetry.



The INS-DH-OEM dual antenna GPS-aided INS from Inertial Labs is an OEM version of their new generation dual GNSS antenna. It is a fully-integrated, combined GNSS (GPS, GLONASS, Galileo & BeiDou) and high-performance strapdown system, that determines position, velocity and absolute orientation (heading, pitch & roll) for any device on which it is mounted. Horizontal and vertical position, velocity, dual antenna heading, pitch & roll are determined with high accuracy for both motionless and dynamic applications with IMU input from the Honeywell HG4930 aided by the NovAtel dual antenna receiver.

The INS-DH-OEM utilizes an advanced dual antenna GNSS receiver, a Honeywell HG4930 IMU which has 3-axes each of advanced MEMS accelerometers (calibrated in full operational temperature range) and new generation of tactical grade MEMS gyroscopes to provide accurate position, velocity, heading, pitch and roll of the device under measure. The INS-DH-OEM contains the new on-board sensors fusion filter, calibration software and state of the art navigation/guidance algorithms from Inertial Labs.
