OxTS, experts in inertial navigation, have introduced a series of updates to the xNAV and xOEM range of products. The result is greater practicality and improved functionality from OxTS’ survey-friendly GNSS-aided inertial navigation systems and lightweight GNSS/INSS board sets.
The already compact xNAV550 dual-antenna GNSS/INS has been further reduced in size and weight. It’s now even better suited to space- and weight-restricted UAV-based surveying applications that still require centimetre-level positioning and accurate roll, pitch and heading data. The xNAV550 now weighs just 395g and has been reduced in height to 43mm.
The xOEM550 dual-antenna GNSS/INS board set is also smaller and lighter than before, with a 4.9mm reduction in height (to only 30.1mm) and a reduction in weight (to 150g).
As well as reductions in size and weight, the xNAV500/xOEM500 and xNAV550/xOEM550 also benefit from reduced power consumption. This further increasing their practicality in the field. An across-the-board saving of 0.5W brings the xNAV500/xOEM500 down to 6.5W and the xNAV550/xOEM550 to 9W.
Furthermore, onboard storage capacity has been increased for all products, to 32GB.
Additional functionality to xNAV and xOEM
- includes ethernet logging of UDP data streams from external sensors, like LiDAR (supporting up to four simultaneous stream logs)
- ethernet output of NMEA data (for external sensor synchronisation)
- external PPS compatibility
The xOEM products have also been upgraded to feature three serial ports on the boardset and offer RS485 support.
All units now have completely field-upgradable firmware and are future-ready thanks to a new ARM CPU that current only uses about 15% of its processing capability during standard use of the INS. This spare processing capacity allows for additional features to be added at a later date without the need for a hardware upgrade.
