Tellumat of South Africa has integrated Spatial Dual into their television telemetry unit being installed into the fleet of stunt planes used in the air race world championship.
Tellumat's PRU (Position Reporting Unit) that integrates Spatial Dual sends real time position, velocity and orientation from the stunt plane to the ground during the races so that graphics can be overlaid on live television footage.
The system has been in trials since March 2014 and based upon successful testing it has now been moved into the production phase. Shown below is one of the prototype PRU systems from July 2014 installed in the stunt plane pictured above.
The production Tellumat PRU is shown below.
The stunt plane air race is an extremely difficult environment for a GPS/INS with high dynamics manoeuvring causing extended duration g-forces of up to 10g and back to back GPS outages of up to 15 seconds during barrel rolls and loops.
Where other systems that were tested failed to achieve satisfactory results, Spatial Dual exceeded in maintaining high accuracy position, velocity and orientation. By fully integrating data from the stunt plane fleet's existing pitot and static air data system, Spatial Dual was able to acheive position drift rates of less than 0.5% of distance travelled during GPS outages in manoeuvres.
The position data from tests carried out in Cape Town, South Africa last year is shown below.
A log file of this data that can be opened in Google Earth can be downloaded from this link.

We hope you enjoy your holidays and look forward to working with you again in the new year.
Spatial FOG has completed a long distance 558 kilometre dead reckoning test in a drive down the eastern coast of Australia. The test duration was 8 hours and 17 minutes and involved difficult terrain with altitude changes of more than 800 metres. Spatial FOG demonstrated market leading performance in the test with an error of just 0.1% of distance travelled.
For the test, Spatial FOG was installed into a 1996 Jeep Cherokee and the factory odometer signal was connected. The factory odometer is low resolution with 0.2 metres per pulse. Spatial FOG was initialised with a manually entered starting position and did not have any GPS antenna connected for the duration of the test. A Spatial Dual unit with antennas connected was installed next to Spatial FOG to provide a high accuracy GPS reference for the test.
The vehicle drove from Waterfall Way in northern New South Wales to Point Piper in Sydney. The course took 8 hours and 17 minutes and involved difficult terrain, sharp cornering, altitude changes of more than 800 metres and ambient temperatures of 42 degrees celsius.
At the end of the test, Spatial FOG's dead reckoning position was compared with the Spatial Dual reference position and the error was found to be just 564 metres or 0.1% of distance travelled. The track and final approach can be seen below with Spatial FOG in blue and the Spatial Dual reference in red.
The results of this test show Spatial FOG's market leading dead reckoning performance even under difficult conditions.
SEA Corporation of Japan has delivered Advanced Navigation's Sublocus DVL to Ocean Works Asia. Ocean Works Asia is integrating Sublocus DVL into their ROV (Remotely Operated Underwater Vehicle) platform for autonomous control. SEA Corporation worked with Ocean Works Asia to perform validation performance testing on one of the units in the waterways of Chiba prefecture, Japan.
As part of the validation performance testing, Sublocus DVL was mounted underneath a ship without GPS and its position, velocity and heading was compared against a dual antenna GPS reference system onboard the ship. Sublocus DVL exhibited excellent performance in the testing. The position results are shown below with Sublocus DVL in blue and the reference unit in red.
SEA Corporation has considerable engineering expertise in marine and subsea technologies and they are Advanced Navigation's exclusive distributor in Japan. For contact information please visit their website at http://www.seanet.co.jp/.
Advanced Navigation has successfully commissioned a high accuracy navigation, heading and leeway system on the renowned racing maxi yacht Wild Oats XI. The new system provides accurate performance metrics that allows the crew to maximise efficiency during races. The system provides accurate data through GPS outages and under the tough conditions of racing at sea. During sea trials earlier this month the system demonstrated excellent results. Wild Oats XI will be competing in the Sydney to Hobart yacht race on boxing day.
PLSM has announced the release of their new subsea surveying buoy platform that integrates Advanced Navigation's Orientus. The buoy platform combines Orientus and an RTK GPS with their USBL acoustic underwater positioning system to provide high accuracy positioning to underwater vehicles.
PLSM utilised Orientus' extensive peripheral support to integrate it with a dual antenna GPS heading system. Orientus smooths out the noise from the dual antenna GPS and maintains heading during any gaps of dual antenna heading outage to provide the system with consistently accurate and reliable heading. It also provides high accuracy roll and pitch which is used to compensate for angular motion of the system in the water.
This combination of an L1 dual antenna RTK system and Orientus has allowed PLSM to obtain very high accuracy position, attitude and heading at a very competitive price that is suitable for use in stationary environments. For moving applications Advanced Navigation recommends the all in one L1/L2/L5 full INS solution of Spatial Dual.
An application note on the integration of Orientus and its performance testing can be found at this link:

Advanced Navigation has announced the release of their Poseidon subsea GPS antenna.
Poseidon is a subsea GPS antenna that is designed for use on underwater vehicles that require the ability to obtain a GPS fix when surfaced. The antenna is also suitable for marine vessels that are exposed to harsh conditions that are too extreme for a normal GPS antenna. The antenna is lightweight, compact, corrosion resistant and able to withstand depths of up to 3000 metres.
Poseidon is the first product to be released from Advanced Navigation's RF division since it was formed last year.
Advanced Navigation has announced the release of their OBDII Odometer vehicle speed interface cable.
The OBDII Odometer is a smart interface cable that communicates with a vehicle's on-board computer to determine the current vehicle speed. It outputs real time vehicle speed over an RS232 serial data interface. When connected to one of Advanced Navigation's Spatial series of GPS/INS products it allows for outstanding navigation accuracy when GPS is not available, down to 0.05% of distance travelled.
With built in support for eleven different OBDII communication protocols, the OBDII Odometer supports almost all modern vehicles on the market. It is completely plug and play with no setup required and can be switched between vehicles in seconds.
On GM, Ford and some European vehicles, the OBDII Odometer is able to retrieve vehicle speed from the ABS (Anti-lock Braking System) system which provides a very high resolution speed. On all other vehicles the OBDII Odometer will provide speed from the transmission which is still a very accurate reference. The OBDII Odometer is also able to determine when the gearbox is in reverse on a range of vehicles.
The OBDII Odometer has a miniature in-line design that is easy to fit into any vehicle. It features a strong ABS plastic shell and tough strain relieved cabling.
The OBDII Odometer is protected from surges, reverse polarity, brown outs and overvoltage to continue operating through harsh electrical conditions. It's communications interface is optically isolated to prevent ground loops and protect sensitive equipment connected to it. It is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance in mind.
Please see the OBDII Odometer product page for more information and the reference manual.
Advanced Navigation is pleased to announce the release of the second generation hardware of their Spatial FOG GPS aided inertial navigation system.
The update includes a major packaging change that more tightly integrates the fibre optic gyroscopes with the GNSS and INS. This provides a significant reduction in power consumption and heat generation as well as requiring only a single connector.
The update also incorporates a new GNSS receiver which adds support for L5 GPS signals as well as the Chinese BeiDou B1 and B2 satellite signals.
Together with the updated hardware, version 2.0 of the Spatial FOG firmware has been released which features significant enhancements to the north seeking algorithm. This allows Spatial FOG to accurately align under conditions that may not have been possible previously.
The updated version 2.0 hardware remains fully backwards compatible with version 1.0, featuring the same mounting footprint, electrical connections and protocol. For existing customers, Spatial FOG version 1.0 will remain available until 2019.
