OxTS Inertial Navigation Systems (INS) are now integrated with any MAVLink compatible flight controller.
MAVLink is a protocol used for communicating with small unmanned vehicles and is widely used by many flight control systems. Through a tested integration, MAVLink compatible flight controllers can now use the measurements created by an OxTS device to better understand the behaviour of their UAV at any given time.
When used alongside an OxTS INS device, a user controlling their UAV with a MAVLink compatible control system will be able to take advantage of both the centimetre-level accuracy of the OxTS device and the wide range of features that OxTS INS users already benefit from, such as those included in our free-of-charge INS configuration, data monitoring and post-processing software NAVsuite.
GNSS-denied navigation.
In most cases, UAVs will operate with full satellite visibility, allowing them to accurately navigate their environment without interruption. However, on occasions when GNSS isn’t available, or signal is jammed, OxTS devices can still operate thanks to a range of software features designed to enable accurate navigation in difficult GNSS environments. These include…
- Generic Aiding Data (GAD) – The OxTS GAD interface comes as standard with any newly purchased OxTS INS. GAD allows a user to feed measurements from external sensors, such as LiDAR, camera and wheelspeed data, into their navigation engine (OxTS INS). This means a more robust navigation solution able to operate efficiently in difficult GNSS environments – Learn More.
- LiDAR Inertial Odometry (LIO) – A specialist implementation of the GAD interface, LiDAR Inertial Odometry uses velocity updates from a LiDAR sensor to constrain position drift in difficult GNSS environments – such as urban canyons. By combating the negative effects of position drift, LIO enables accurate navigation with or with out GNSS – Learn More.
- Gx/ix – The gx/ix tight-coupling feature, available on all OxTS INS devices, improves navigation data in tough GNSS conditions. The inertial relock feature cuts down the time taken to reaquire satellite signal after an outage and single satellite aiding enables the OxTS INS to continue computing position when less than four satellites are visible – Learn More.
