It may be small, but the new xNAV500 represents a big addition to our xNAV line-up as the first model to feature real-time output of measurement data. Due to launch in the third-quarter of 2014, the xNAV500 builds on the success of the xNAV200, and is aimed squarely at UAV and UAS applications where payload restrictions mean the size and weight of GPS-aided inertial navigation sensors are almost as important as their measurement accuracy.
With a mass of just 380 g and small enough to fit in a coat pocket, the xNAV500 packs a lot of technology into a small space. Featuring dual GPS receivers and a state-of-the-art custom built inertial measurement unit, the xNAV500 constantly monitors position, orientation and velocity with high accuracy, and outputs those measurements via Ethernet and RS232 serial at 100 Hz. Just like the xNAV200, 4 GB of on-board storage is available, allowing four days’ worth of measurements to be stored internally. Data can be easily downloaded from the system and post-processed using our advanced software, which is included as standard at no extra cost.
Interfacing the xNAV500 to cameras, laser scanners or other sensor arrays is easy thanks to the xNAV500’s digital input, which can be used to generate event-driven navigation messages that are time-stamped to external events. The easy to use configuration software, NAVconfig, also allows the xNAV500 to generate distance-based signals that can be used to trigger external equipment. These features, and the convenience of the one-box solution, ensure it is quick and easy to acquire the accurate exposure point data required for direct-georeferencing.
The real surprise about the xNAV500 though is its performance/cost ratio—which is one of the best in the sector. And with sub-metre position accuracy and a stable heading accuracy of 0.06°, the xNAV500 is sure to be on the shortlist for all unmanned aerial applications that require georeferencing data, from photogrammetry and remote mapping to crowd surveillance.
