From all the team at Advanced Navigation, we would like to wish all of our customers and suppliers a very merry christmas and a happy new year.
Unlike most of our customers that are looking forward to a white christmas, we will be enjoying aussie style christmas's of beaches, boating and barbeques in the Australian summer heat. We are looking forward to the new year ahead which will see some very exciting new developments at Advanced Navigation. 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/.
