Orientus is a ruggedized miniature orientation sensor and AHRS (Attitude & Heading Reference System) that combines temperature calibrated MEMS accelerometers, gyroscopes and magnetometers using a state-of-the-art fusion algorithm to deliver accurate and reliable orientation in even the most demanding environments.
Orientus features advanced filtering that detects and adjusts for magnetic interference. Its sophisticated algorithm compensates for short-term linear accelerations, allowing the sensor to maintain accurate roll and pitch measurement. Long term linear accelerations can also be dealt with via addition of an external GNSS receiver for full linear acceleration compensation.
Orientus is enclosed in a precision-machined marine grade aluminium enclosure. Waterproof and dirtproof to IP68 standard and shockproof to 2000g, the system maintains high reliability in the most extreme conditions. The minimal size, weight and power requirements make it ideal for unmanned vehicle applications such as platform and camera stabilization, as well as a heading reference source for unmanned surface vehicles.

Motus is a miniature ultra-high accuracy MEMS IMU (inertial measurement unit) that combines ultra-high accuracy accelerometers and gyroscopes with magnetometers to provide inertial performance that exceeds even some FOG IMUs.
With a volume of just over 1 cubic inch and a weight of only 26 grams, Motus is ideal for SWaP-conscious applications, such as geopointing and LiDAR 
missions with VTOL UAVs. The system is available in an OEM package suitable for integration into larger products, or an enclosed package for external and standalone use.
Motus can be upgraded to full AHRS or INS capability through a simple software license upgrade. With INS capability it can be interfaced to many leading brands of GNSS receivers to create a complete OEM GNSS/INS solution.

Certus and Certus Evo are rugged low-SWaP, ITAR-free GPS-aided INS and AHRS modules that combine temperature-calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with a dual antenna RTK GNSS receiver, all coupled with a cutting-edge AI-based sensor fusion algorithm.
Certus modules incorporate dual antenna moving baseline RTK, providing highly accurate heading data for both stationary and moving vehicles even in magnetically problematic environments.
The RTK GNSS receiver provides up to 8mm accuracy positioning and supports all of the current and future satellite navigation systems.
Certus and Certus Evo are ideal for UAV and USV surveying, antenna and weapons platforms targeting, and stabilization of robotic systems.

Spatial is a ruggedized miniature GPS-aided INS (inertial navigation system) and AHRS that provides accurate position, velocity, acceleration and orientation outputs. It couples high-performance MEMS inertial sensors and a pressure sensor with an advanced GNSS receiver using an AI-driven fusion algorithm to deliver accurate and reliable navigation and orientation.
Spatial’s GNSS receiver supports all current and future satellite navigation systems including GPS, GLONASS, GALILEO and BeiDou. It features L1 RTK which can provide positioning accuracy of 2cm and also supports kinematic post-processing accuracy of 1cm.
A next generation battery backup system allows Spatial to hot start inertial navigation from its last position in 500 milliseconds and obtain a GNSS fix in approximately 3 seconds. Our Spatial series are the only GNSS/INS in the world to provide this unique capability.
With low SWaP requirements, Spatial is ideal for UAV surveying and geo-referencing missions, as well as tracking, security and platform stabilization for a wide range of robotic systems.

Spatial FOG is a ruggedized GPS-aided INS and AHRS that combines ultra-high accuracy fibre optic gyroscopes, accelerometers, magnetometers and a pressure sensor with an RTK GNSS receiver. The integrated KVH Industries 1750 FOG IMU provides extremely accurate inertial data far beyond the best MEMS technology available, and allows Spatial FOG to achieve very high accuracies and dead reckon without GNSS for extended periods of time.
Spatial FOG’s triple frequency Trimble RTK GNSS receiver provides up to 8mm accuracy positioning and supports all of the current and future satellite navigation systems.
The system also features a revolutionary north seeking algorithm that is able to provide accurate heading in as little as 10 seconds after power on from a hot start and 10 minutes from a cold start. This algorithm runs continuously while in operation and is not effected by velocities or angular movements, allowing the system to provide high accuracy heading in environments where magnetometers and GPS aided heading cannot be used.
Extremely low drift rates make Spatial FOG an ideal choice for high-accuracy unmanned vehicle navigation in GNSS-denied environments. This highly accurate data output also makes it well suited to UAV geo-referencing and surveying applications.

The Spatial FOG Dual is a dual-antenna moving baseline RTK variant of the Spatial FOG GPS-aided INS/AHRS. It provides highly accurate heading output while both stationary and moving. The triple frequency Trimble RTK GNSS receiver provides up to 8mm accuracy positioning and supports all of the current and future satellite navigation systems, as well as the Omnistar service for even higher accuracy positioning.
The Spatial FOG Dual is ideally suited for unmanned vehicle operations where single antennas struggle or where additional heading accuracy is required, such as unmanned marine surveying platforms. It is also ideal for use in unmanned helicopters, where high levels of magnetic interference make magnetic heading unusable and single antenna GNSS/INS systems can have issues resolving the heading due to the 3D movement and stationary hovering of the platform.
