El xNAV650 es el INS m\u00e1s peque\u00f1o, liviano y asequible de OxTS hasta la fecha, combinando tecnolog\u00eda MEMS IMU (unidad de medici\u00f3n inercial) de \u00faltima generaci\u00f3n con receptores GNSS de grado topogr\u00e1fico para brindar confiabilidad y precisi\u00f3n para el mapeo de UAV (veh\u00edculos a\u00e9reos no tripulados) y topograf\u00eda. El socio de OxTS, Dronezone, ha utilizado el xNAV650 INS junto con un Velodyne VLP-16 para realizar un escaneo de un puente envejecido para buscar peligros estructurales y potenciales del follaje demasiado crecido. Al fusionar los datos de tiempo, posici\u00f3n e inercia del INS con los datos sin procesar del Velodyne VLP-16 a trav\u00e9s del software Georeferencer de OxTS, el top\u00f3grafo pudo producir una nube de puntos 3D de alta precisi\u00f3n del puente.<\/p>\n

Oxford Technical Solutions<\/a> (OxTS) has launched the latest in the company\u2019s line of inertial navigation systems (INS). The xNAV650 is OxTS\u2019 smallest, lightest and most affordable INS to date, combining state-of-the-art MEMS IMU (inertial measurement unit) technology with survey-grade GNSS receivers to provide reliability and precision for UAV (unmanned aerial vehicle) mapping and surveying.<\/p>\n

The xNAV650<\/a> delivers absolute position, timing and inertial measurements (heading and pitch\/roll) that can be combined with data from other devices such as LiDAR sensors and cameras to greatly enhance the results of the surveying process. Measuring 77 x 63 x 24 mm and weighing just 130 g, it is ideal for SWaP (size, weight and power)-constrained drone platforms.<\/p>\n

OxTS\u2019 partner Dronezone has used the xNAV650 INS in conjunction with a Velodyne VLP-16 to conduct a scan of an aging bridge to look for structural and potential hazards from overgrown foliage. By fusing the timing, position and inertial data from the INS with the raw data of the Velodyne VLP-16 via OxTS\u2019 Georeferencer software, the surveyor was able to produce a highly accurate 3D pointcloud of the bridge.<\/p>\n

This data fusion resulted in an excellent level of clarity that can be seen in the foliage, electricity lines and side of the bridge. The resultant pointcloud has enabled the engineers to easily and accurately pinpoint areas of the bridge that need closer attention.<\/p>\n

The data from OxTS INS can be fused with the data from almost any LiDAR sensor, and the OxTS Georeferencer software can be used to georeference pointclouds specifically from Velodyne, Hesai and Ouster sensors. OxTS is currently working to integrate new LiDAR sensors from an even wider range of manufacturers into OxTS Georeferencer, allowing users to build a full navigation solution where much of the integration work is already taken care of.<\/p>\n

The xNAV650 is ideal for a wide range of UAV mapping and surveying applications, including:<\/p>\n
