Advanced Navigation has announced the release of their GNSS/INS post processing software Kinematica.
Kinematica is easy to use web based GNSS/INS post processing software that allows users to process raw GNSS and inertial data after collection and achieve higher accuracy position, velocity and orientation than is possible in real time.
The software supports kinematic GNSS positioning which provides a 200x increase in position accuracy over standard GNSS with 8mm position accuracy. Dual antenna GNSS heading processing is also supported.
Kinematica processes data in forwards and reverse six times which allows it to fill any satellite outages and ignore errors that would normally affect a real time solution.Both loosely and tightly coupled GNSS/INS processing is supported and the software automatically switches between each mode depending upon the environment.
Kinematica currently supports all of Advanced Navigation's GNSS/INS products.
Kinematica is targeted at surveying, scanning and aerial photography applications that need to squeeze the maximum performance out of their systems.

Advanced Navigation has announced the release of their interface and logging unit. The interface and logging unit (ILU) is a device server that interfaces to any of Advanced Navigation's systems and provides data logging, a web interface, a time synchronisation server and a wide variety of different industry standard data input/output options.
The ILU features 6 RS232/RS422 serial ports, 1 CAN bus, 2 ethernet ports, WiFi and an array of multi-function GPIO pins. All of the interfaces can operate simultaneously with input and output of data in a large selection of different formats. Every single interface is individually optically isolated to prevent grounding issues with other equipment. The system supports both input and output of most major protocols including NMEA 0183, NMEA 2000, TSS, Simrad as well as a number of widely used proprietary protocols.
Data logging is supported from both the connected Advanced Navigation device and every other one of its interfaces simulataneously. Data can be automatically timestamped on arrival for easy synchronisation. The system contains 64GB of logging capacity which can allow the unit to log for months.
The ILU functions as an accurate GPS disciplined oscillator and has the capabilities of a full time synchronisation server. Its timing synchronisation outputs include 1PPS, 10 Mhz, hardware PTP as well as a number of other protocol based synchronisation outputs such as NTP and GPZDA.
A rich web interface features live mapping, real time data plotting and full configuration of devices. The ILU supports all of Advanced Navigation's products and the web interface dynamically reconfigures based upon what it is connected to.
The ILU is housed in a rugged marine grade aluminium enclosure that is water proof and dirt proof to the IP68 standard. The system features surge, static, overvoltage, short circuit and reverse polarity protection on all of its interfaces.
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.
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 email@example.com to purchase a bluetooth dongle.
