GPS IMU

GNSS-INS Solutions: IMUs for Inertial Navigation

NavtechGPS is a distributor of GPS / GNSS aided inertial navigation systems (INS) for commercial and tactical use, including miniature MEMs inertial measurement units (IMU) and attitude heading reference systems (AHRS).

Inertial navigation systems, or INS, is a navigation device that uses a device, motion sensors (accelerometers), and rotation sensors (gyroscopes) to continuously calculate the position, orientation, and velocity of a moving object without needing external references.

We also offer best-in-class GPS IMUs. A GPS IMU, an IMU is an electronic device that measures and reports on a vehicle’s velocity, orientation, and gravitational forces, using a combination of accelerometers and gyroscopes. IMUs are often used in conjunction with GPS, as they can provide accurate motion information even when GPS data is unavailable. It can also help detect spoofing and jamming scenarios. This data is available in a raw format to the user or can be calculated by the GNSS receiver in the system for real-time output to an external device.

Our GPS IMUs come from leading manufacturers such as Setpentrio NovAtel, OxTS and VectorNav Technologies. These GPS IMU/INS products can be used for commercial, industrial, and military applications, including:

Autonomous vehicles, UAV/UAS navigation, Antenna pointing, Robotics, Camera stabilization, Platform stabilization, Heavy machinery monitoring, Primary or secondary flight navigation, and more!

NovAtel Inertial Navigation Systems (NovAtel SPAN®)

NovAtel SPAN® GNSS Inertial Navigation Systems and IMUs integrates NovAtel’s industry-leading Global Navigation Satellite System (GNSS) technology with Inertial Measurement Units (IMUs) to create a tightly coupled GNSS INS solution at data rates up to 200 Hz, for reliable, continuously available, position, velocity and attitude-even through short periods when satellite signals are blocked or unavailable. A wide range of receiver, IMU, and antenna options are also available from NovAtel to meet accuracy and size requirements for nearly any application. SPAN® GPS IMUs can be further optimized for accuracy through cutting-edge post-processing software provided by our Waypoint ® Products Group.

OxTS (Oxford Technical Solutions)

OxTS focuses on high-accuracy, cost-effective inertial navigation systems using MEMS gyros and precision accelerometers. Since its founding in 1998, OxTS has stood out as inertial navigation system experts committed to helping customers accurately measure position, time, orientation, and dynamics in all possible environments. Its Kalman filter extracts the maximum information from GPS, delivering high-accuracy measurements and low drift rates. The xOEM series of inertial navigation systems is an extremely lightweight and compact 3-D navigation solution as an embedded GNSS INS board set, allowing manufacturers to integrate it directly into their products. OxTS products do not use magnetometers, so there are no effects from ferrous metals or electrical interference from outside sources! And ALL OxTS systems include post-processing software an no additional charge! OxTS also partners with manufacturers to integrate their inertial navigation system technology directly into supplementary products to streamline functionality. These features and more empower OxTS to continue to provide comprehensive GPS IMU solutions for automotive, survey and mapping, and autonomy industries.
