Advanced Navigation has released a free program for testing their inertial pedestrian navigation technology currently in the final stages of development. The program can be used to post process data from a leg mounted Spatial unit for indoor pedestrian navigation.

Advanced Navigation's pedestrian navigation technology is designed for human navigation through areas where GPS signals are not available such as indoor environments. It has been developed for tracking personnel in high risk environments such as mine sites and chemical plants. The technology is being developed into rechargable ankle mount trackers that send real time data back to a central server over WiFi.

The navigation filter has been extensively tested in a number of different environments and has reliably demonstrated positioning performance of less than 4% of distance travelled over extended time periods. The filter uses a combination of step detection, stride estimation and a number of novel algorithms to deliver reliable navigation performance under a broad range of environments.

Shown below is results from testing on a basketball court where the position can be easily compared with the court lines from satellite imagery.

In this test the position error was 0.8% of distance travelled. A log file of the results that can be opened in Google Earth can be downloaded from this link.

The free post processing program that can be used to test the technology with a Spatial device can be downloaded from this link. The program requires that the raw sensors packet be set to output at 200Hz and it is recommended to have the system state packet output at 200Hz for timing, initialisation and error checking. The program generates output log files in the same directory as the input ANPP log file. It does not use the Spatial position, velocity or orientation except for optional automatic initialisation.

The Spatial unit should be mounted on the ankle as shown in the image below.

Advanced Navigation has released a version of their Spatial Manager software for Android devices.

The Android version of Spatial Manager features data logging, a built in NTRIP client for easy RTK and real time data views. It can also override the Android device's internal GPS so that the high accuracy Spatial data can be used by other Android applications. It is ideal for mobile surveying work with Advanced Navigation's Spatial series of GPS/INS systems.

Spatial Manager for Android is now available in the Android Play Store free of charge at this link. The Android device connects to the Spatial system wirelessly over bluetooth. A bluetooth dongle is required to use the Android application. Please contact to purchase a bluetooth dongle.

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.

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

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:
