Advanced Navigation is a leading developer of high accuracy navigation technologies for Commercial and Defense applications. Our MEMS (Micro Electro-Mechanical systems) and FOG (Fiber Optic Gyro) based navigation products are ideal for a wide range of UAV (unmanned aerial vehicle), UGV (unmanned ground vehicle) and AUV (autonomous underwater vehicle) applications.
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.

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.

Subsonus is a next-generation USBL underwater acoustic positioning system combining an industry-leading eight channel factory calibrated hydrophone array with an internal tightly coupled INS. Capable of operating at depths of up to 1000 metres, it fuses acoustic position and doppler velocity with factory calibrated inertial sensors and a depth sensor, providing highly accurate position, velocity and heading outputs.
Subsonus dynamically adjusts its acoustic transmit power based upon ranging distance, resulting in highly improved short range performance by significantly reducing noise and multipath. The system features the ability to measure the speed of sound through water using a revolutionary new technique, which means that it is self-tuning and no extra equipment or user intervention is required to setup the system.
Subsonus is ideal for station keeping, control and subsea surveying applications for both AUVs (autonomous underwater vehicles) and ROVs (remotely operated vehicles).

Kinematica is web-based GNSS/INS post-processing software for raw GNSS and inertial data from any of our GNSS/INS products.
Kinematic GNSS post-processing provides an up to 200 times increase in position accuracy over standard real-time GNSS. The Kinematica software automatically downloads the closest RINEX base station data and outputs position to an accuracy of 8mm.
Kinematica utilises forward and backwards looking in time to fill satellite outages and compensate for errors that would normally affect a real-time solution. It also supports both loosely and tightly coupled GNSS/INS processing, automatically switching between them to provide the best accuracy results under the conditions at that point in time.
Ideal for post processing data acquired from surveying, LiDAR and aerial photography applications.
