Validating traffic sign recognition systems? New tool makes it easier and quicker to survey Feature Points with RT-Range S

With the latest software update, the user interface of the OxTS RT-Range software has been enhanced to make real-time testing of vision based ADAS sensors, capable of detecting road signs or traffic signals, much quicker. OxTS’ unique Feature Point technology means automotive engineers can create feature point files representing objects such as traffic lights or road signs and then load them into the RT-Range. The RT-Range can then output all standard range measurements (longitudinal range, lateral range, resultant range, time-to-impact etc.) once the feature point enters the sensors’ field-of-view. This gives users almost limitless freedom when planning realistic test scenarios for validating vision based ADAS sensors. RT-Range software with new Feature Point Survey wizard   The new Feature Point survey tool now makes it even easier to collect these points before loading them into the RT-Range Hunter. The Feature Point Survey Wizard is designed to allow engineers to quickly and efficiently create Feature Point files using the real-time position information being output by the OxTS RT systems. Points can be created in response to a button press, or at regular time/distance intervals. Each new point is automatically numbered, and is fully defined using the current lat/lon, altitude and heading. Setting up a sensor's field-of-view in RT-Range software   Feature Point Surveys conducted over large areas can be carried out swiftly by mounting the RT system in a vehicle, and applying a displaced output to it. The displaced output should relate to a marked position on the vehicle perimeter, such as the front bumper. The driver can then simply drive up to points of interest until the displaced output point is touching the object, then press a button to create a Feature Point. All data points can be manually edited afterwards if it’s not possible to drive directly to the desired location. Once saved, Feature Point files can simply be uploaded to an RT-Range system. Feature points enter field-of-view   The RT-Range is one of the most comprehensive and trusted solutions used globally for developing advanced driver assistance systems. Being able to conduct tests with multiple mobile targets, fixed targets as well as feature point targets such as road signs, is just one of the reasons the RT-Range is so popular with automotive engineers. For more information on how the RT-Range can help you, or to discuss your own specific requirements, please contact OxTS directly or your national OxTS representative.

Latest NAVsuite release promises reduced workload for automotive engineers

The latest release of our NAVsuite software has been designed to do just one thing—to make life easier for automotive engineers. So while the user interface hasn't changed a great deal, there have been some big changes behind the scenes. The most important of which are the new co-ordinate systems that are available on the CAN bus. While our GNSS-aided inertial navigation systems retain the previous earth-fixed NED, horizontal and vehicle based reference frames, they now output additional measurements using the popular systems defined in ISO 8855. This seemingly small change should save engineers plenty of time as it removes the need to convert measurements between different co-ordinate systems. The new CAN bus outputs include measurements in an earth-centered, earth-fixed ENU system, ISO 8855 intermediate system and ISO 8855 vehicle based system. For vehicle dynamics and other automotive based work, DIN 70000 is often the coordinate system used. Based on the ISO 8855 international standard for vehicle dynamics and road holding ability, DIN 70000 is an equivalent German standard used by many manufacturers of passenger cars, buses and other commercial vehicles. This is especially of interest to our large German customer base who can now use the vehicle coordinate system according to DIN 70000. For more information on our comprehensive range of automotive test and validation equipment, or to enquire about the latest software releases, please contact your regional OxTS representative, or email our sales team at sales@oxts.com. OxTS bietet nun die Mӧglichkeit Daten auch im Fahrzeugkoordinatensystem nach DIN 70000 auszugeben Die neuste Version unserer NAVsuite Software ermӧglicht es Messdaten nicht nur in unserem traditionellen Inertial-basierten Koordinatensystem, sondern auch im fahrzeugfesten Koordinatensystem gemäß DIN 70000 auszugeben. Basierend auf ISO 8855, dem internationalen Standard  für Straßenfahrzeuge, Fahrzeugdynamik und Fahrverhalten, wird das Koordinatensystem nach DIN 70000 vor allem von deutschen Fahrzeugherstellern verwendet.

OxTS RT-Range S software release – ADAS testing to Euro NCAP AEB VRU protocol

As ADAS testing is getting more complex, car manufacturers need a reliable measurement system for complicated tests including multiple vehicles in realistic traffic scenarios. The OxTS RT-Range S is one of the most trusted and comprehensive solutions used globally for demanding ADAS tests such as NHTSA FCW, LDW or Euro NCAP AEB. New software and firmware release OxTS has now further increased the system's extensive feature list by adding the ability to realistically recreate the shape of Hunter vehicles (VUT) and Targets with up to 24 points. The RT-Range S automatically calculates range measurements to the nearest polygon point. Using this tool, you can place a virtual polygon shape of up to 24 points around any vehicle, pedestrian, cyclist or fixed point to be used in any given test scenario - measuring range, time-to-collision, visibility etc. all from the nearest polygon point on the Hunter vehicle, to the nearest point of any of the target vehicles. Crucially, this additional feature now makes it possible to easily conduct a number of ADAS system tests using the RT-Range system all to the vehicle front end virtual profiling definitions within the latest EuroNCAP AEB VRU protocols.   Euro NCAP AEB VRU pedestrian and cyclist tests Park assist validation   Custom, user-definable points around the hunter vehicle is the latest addition to a long list of features such as driving robot interface, tracking of multiple targets which can be other vehicles, pedestrians and feature point targets like road signs, CAN data acquisition, open road ADAS testing with DGPS corrections via NTRIP, car-to-pedestrian testing with the RT-Backpack etc. Customers on a support contract can now benefit from this feature. Please contact Support or your local representative.

Networked DGPS allows differential corrections to be shared from one vehicle to multiple vehicles in a WLAN network

Differential GPS corrections being received by one OxTS device can now be shared wirelessly between multiple devices in a WLAN thanks to the networked DGPS feature in the latest release of NAVsuite. While this enhancement saves money and reduces system complexity, it also gives car manufacturers even greater flexibility when evaluating ADAS sensors in public traffic. Differential GNSS corrections can be transmitted or received on the IP network, e.g. over the RT-XLAN, allowing multiple devices to share a single correction source. This means only one INS on a network needs to receive those corrections on a serial interface from an external source, such as NTRIP via a radio or modem. That INS then acts as the "Network Corrections Transmitter (NCT)" and sends the corrections over the network as UDP datagrams. Other INS units on the network act as "Network Corrections Receivers (NCR)" capturing the UDP broadcast differential corrections and using them as if they had been received directly via a radio modem.             Using this system reduces complexity in situations where multiple RTs need DGPS corrections as only one pair of radio modems needs to be used. Customers can configure this feature in the “Differential corrections” window in the “Options” tab of NAVconfig (see screenshot below). For more information please contact Support (support@oxts.com) or your local rep.

OxTS NAVsuite release 2015

OxTS - NAVsuite software release Our latest version of the OxTS NAVsuite software suite is now available for customers on a support contract. We have added new features and enhancements such as an increased output rate for our xNAV systems, integration with Locata receivers for our Inertial+, and differential GPS corrections being received by one RT can now be shared wirelessly between multiple vehicles in a WLAN network thanks to the networked DGPS feature in the latest release of NAVsuite.   Networked DGPS allows differential corrections to be shared from one vehicle to multiple vehicles in a WLAN network Easier to set-up—cheaper to operate. Our new networked DGPS feature shares differential corrections between multiple vehicles using only one pair of radio modems. Differential GPS corrections being received by one OxTS device can now be shared wirelessly between multiple devices in a WLAN thanks to the networked DGPS feature in the latest release of NAVsuite. While this enhancement saves money and reduces system complexity, it also gives car manufacturers even greater flexibility when evaluating ADAS sensors in public traffic. Read more... OxTS create the world’s first Locata+INS system OxTS have successfully integrated a Locata receiver with their Inertial+ to create the world’s first Locata+INS device—capable of achieving cm level accuracy where GPS systems fail. Locata is an innovative positioning system designed to complement rather than replace GPS, by addressing the issues and shortfalls of a Global Positioning System. The Inertial+ allows Locata users to take advantage of their existing technology while enjoying the extra layer of measurements an aided inertial navigation system brings. Read more... Inertial+ can now take advantage of dual-antenna receivers and take heading from an external receiver With the latest NAVsuite release, it is now possible for the Inertial+ to generate heading information from an external receiver instead calculating it using the internal receivers. This new option forces the Inertial+ to take its heading information from a dual-antenna external receiver. The benefits of this to customers, besides simply meeting individual requests for such a feature, is a small reduction in the time required to acquire the measurements required to generate heading information and freedom to use larger antenna separations (up to the manufacturer’s limit). The larger antenna separation should result in better quality heading measurements. Read more... The update rate of our smallest INS just got bigger A new feature code for xNAV devices significantly increases their base logging and output rates from the default 100 Hz to a maximum of 250 Hz—matching the speed of our other, much larger products. The update allows the IMU rate to be set to 100, 200 or 250 Hz, and comes in response to the number of users interfacing xNAVs with scanning equipment; many of which commonly uses a standard rate of 200 Hz.

Dual receiver systems get improvement with GLONASS heading calculations

OxTS has improved its GNSS navigation processing so that it can now take advantage of GLONASS signals in the dual antenna heading calculations. Our dual receiver inertial navigation systems like the RT3000, Survey+, and xNAV are able to use GLONASS, which can now also be enabled on the secondary receiver. The benefit of utilising GLONASS on the secondary receiver is that once heading is initialised, there should be significantly more satellites in view meaning the heading solution will be more robust. More satellites means it is easier for the Kalman filter to reject bad updates from multipath effects and refine the heading to achieve the most accurate solution. These benefits aren’t only available to new customers either. Existing users with dual antenna systems can easily upgrade their INS in the field to take advantage of the new enhancements. Contact sales@oxts.com for more information. This is only the beginning however, as we plan to continue development and always strive to improve performance. The coming projects will not only improve heading performance after initialisation but will help speed up heading initialisation to begin with, particularly useful for users who require static initialisation. To make sure you can get access to these enhancements as soon as they’re available, don’t forget to look at the OxTS Support Contracts.

OxTS customers can now use local geoid coordinate systems

Our latest software suite now supports locally defined geoids in post-processing. OxTS customers working in cartography, topographic mapping and other GIS applications can now work with local geoid coordinate systems. We have enhanced our NAVsuite to provide configurable EGM2008 geoid support. Currently OxTS offer altitude output with reference to either the WGS84 ellipsoid or the EGM96 geoid. Some cartographers however may work with different coordinate systems such as a local geoid. By adding EGM08 geoid to the post-process output we can support users who require alternate options. The first example is a geoid covering Spain and Portugal, which is a further adjustment from EGM08.  The EGM08 geoid and some variations (EGM08 REDNAP) will be available as a reference for altitude in post-processing. Our customers can download the geoid definition file from our website. There is also scope to make more geoids available to download and use in the future in addition to EGM08. For customers already familiar with our software The “Altitude” option in NAVconfig is now called “Coordinate system”. If you click the "…" button the “Coordinate system properties” window opens (see below screenshot).                             When "Geoid custom" is selected the browse box appears. This allows our customers to load in a custom geoid file in order to use local geoids as a reference. The geoid definition files will be available to download from the OxTS website. In this release we are implementing the EGM2008 and EGM2008-REDNAP geoids. We are planning to make additional geoids available in the future. This new feature is available with the latest software release, which can be obtained if you’re on a support contract.

Improved drift performance with vertical advanced slip technology

OxTS customers working in adverse GNSS conditions such as inner cities or tree covered areas can now benefit from improved drift performance with our new vertical advanced slip technology. An extension of our existing advanced slip technology, vertical advanced slip creates a coupling in the Kalman filter between the vehicle pitch angle and vertical velocity. This means that in situations where the GNSS signal is blocked or lost, the vehicle velocity is computed from the IMU measurements and constrained to the direction of travel. When used in conjunction with a DMI or wheelspeed odometer, the position drift is greatly reduced and maximum accuracy is maintained. When GPS signals are unavailable, there is no aiding update to constrain vertical navigation errors in position and velocity. The new vertical advanced slip feature stabilises the vertical motion and allows the navigation outputs to remain usable through GPS outages of up to 5 minutes (when combined with horizontal advanced slip and wheel-speed updates). This is particularly important to users carrying out precision work in harsh GNSS environments, such as mobile mapping in urban environments with the Survey+ or conducting open road ADAS tests with the RT-Range S. For existing customers already familiar with our configuration software NAVconfig, here is how to enable vertical advanced slip. Vertical advanced slip can be enabled on the “Advanced Slip” page in NAVconfig (if you are working with one of our RT products) or on the “Wheel Configuration” page in NAVconfig (if you have a Survey+, Inertial+ or xNAV product from OxTS).                 This new feature is available with the latest software release, which can be obtained if you’re on a support contract.
