Nexans Olex has successfully integrated Advanced Navigation's Spatial INS into their hydrographic survey vessels. Spatial is a ruggedized miniature GPS aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration and orientation. It combines temperature calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with an advanced GNSS receiver.
Olex was seeking a replacement inertial navigation system to integrate into their multibeam sonar mapping systems. They needed more accurate position & orientation data than their existing inertial navigation system could provide and also wanted to make the system more affordable to bring in customers who were previously excluded due to the high costs.
Spatial was chosen amongst other navigation systems because:
Another key advantage of Spatial is its high compatibility with existing systems allowing it to be integrated with Atec, Wassp, HGPS and many other platforms.
The use of the Spatial system resulted in higher accuracy data and better mapping. Precise navigation data is a key focus with Spatial, promising to deliver 0.1 degrees accuracy in pitch and roll, 0.2 degrees in heading, and 5 cm or 5% in heave. All of this is done at an exceptionally competitive price making it a popular choice in the hydrographic survey market.
Experimental testing from Olex demonstrates the easy installation, accurate data & wide range of compatibility of the Spatial system to existing platforms.

Advanced Navigation is pleased to announce the release of their new GNSS/INS Spatial FOG Dual. Spatial FOG Dual is a new variant of the popular Spatial FOG product that features the addition of high accuracy dual antenna heading.
The system operates with two GNSS antennas that are mounted fore and aft on the vehicle. By continuously measuring the phase difference of the GNSS signal received on each of the antennas, it is able to calculate the bearing between the two antennas which provides a very high accuracy heading source. This heading source provides the same level of accuracy in both stationary and moving applications and is not affected by magnetic interference making it more accurate and reliable than single antenna systems and magnetic heading systems.
Spatial FOG Dual features the very latest in dual antenna GNSS technology with the new Trimble MB-One integrated.
The product is targeted at survey applications which can benefit greatly from the increased heading accuracy especially under low dynamics conditions.

Advanced Navigation has announced the release of their air data unit. The air data unit measures pitot airspeed and barometric altitude pressure on fixed wing aircraft. It can be used standalone for air data or connected to one of Advanced Navigation's Spatial series of GPS/INS products for significantly enhanced dead reckoning performance in fixed wing aircraft.
The Air Data Unit features very high accuracy absolute and differential pressure sensors. These are factory calibrated over a wide temperature range to further increase measurement accuracy and provide the best air data possible through varying conditions. On top of factory temperature calibration, every time the air data unit powers up, it performs a self excitation calibration to adjust for small deviations of bias and scaling error. This allows the system to compensate for calibration ageing and means that it never needs to be returned to the factory for recalibration.
The system outputs air data at 20 Hz over an RS232 serial interface and is housed in a miniature rugged environmentally sealed enclosure.

Carnegie Wave energy has integrated Advanced Navigation's Spatial Dual into their CETO wave energy power plant. CETO is currently the only operating wave energy power plant in the world and the first ever to be connected to the grid.
Carnegie Wave's CETO 5 wave energy power plants have now been operating for a total of 3000 hours off the coast of Western Australia. In February 2015 a CETO unit was connected to the electricity grid marking a major milestone.
Spatial Dual is used on the CETO power plants to monitor operational performance as well as provide early warning on any problems that may arise. The position, velocity, heave, roll, pitch and heading output from Spatial Dual are carefully monitored.
The environment of CETO puts Spatial Dual's inertial navigation performance to the test. As large waves pass over the CETO unit, Spatial Dual's GPS antennas become submerged and it navigates solely on inertials until the wave passes. This cycle repeats continuously.
A photo of CETO fully submerged with antennas protruding in its normal installed state is shown below.
The full unit out of water can be seen below.
