OxTS xNAV550 integration with Z+F LiDAR scanners

The OxTS xNAV550 GNSS-aided inertial system and Z+F PROFILER® 9012 were mounted on a vehicle roof and connected to each other using a custom interface cable. This provided an accurate 1PPS time stamp and regular NMEA messages in real-time for the Z+F PROFILER® 9012. Once configured, the Z+F system was set to record and the xNAV550 was left to log

Why use a survey-grade Inertial Navigation System on an Unmanned Aerial Vehicle?

Understanding flight dynamics When undertaking any form of flight, it is important to understand the orientation of the aerial platform, the nature of its motion and the direction in which it is heading.  In the context of unmanned aerial vehicles (UAV), these characteristics of flight might be understood by the pilot simply observing the UAV platform’s motion when flying within

OxTS gx/ix technology – intelligent GNSS processing for improved performance

What is gx/ix™? OxTS gx/ix technology is a powerful GNSS/inertial tight-coupling technology developed to take full advantage of OxTS’ extensive knowledge and experience in GNSS and inertial integration, Kalman filtering, and navigation processing. It is a combination of two independent technologies, gx and ix, which are each designed to improve performance in different scenarios. With gx/ix then, the system can

Why use an inertial navigation system (INS) with a LiDAR?

What is LiDAR? Light detection and ranging (LiDAR) technology is a technology used widely in the surveying community to collect high precision three-dimensional (3D) survey data.  This generic description of a LiDAR’s mechanism also applies to another commonly used term, laser scanning, and so in the following descriptions these terms will mostly be used interchangeably.  LiDAR systems collect data by

Why is an Inertial Navigation System (INS) important for unmanned aerial vehicle (UAV) survey and mapping applications?

What is an unmanned aerial vehicle? Recent years have seen an increase in the deployment of aircraft that do not have a manned pilot on board.  These unmanned aerial vehicles (UAV) are also commonly known as drones, unmanned aircraft systems (UAS), or remotely-piloted aircraft systems (RPAS).  For the purposes of the following descriptions, these terms will be used interchangeably.  Drones
