97 SIGINT data from software-defined radios, or video from other cameras) can be fused with the GMB-450’s own data. “And perhaps most importantly, for the gimbal’s data processing, we’ve gone from the NVIDIA Xavier NX to the NVIDIA Orin NX, giving three to four times the compute power,” Friberg added. “We’re the only gimbal manufacturer in the industry that takes the raw sensor data directly into the GPU, and also offers an API so that end-users can install and run their own software on the gimbal, while keeping the price at about half that of competing gimbals.” UAV Navigation-Grupo Oesía has expanded its GNSS-free navigation capabilities with the release of VNS03 – the third generation of its Visual Navigation System. In addition to using an EO camera for visual odometry and template matching, (the use of visible reference points below the UAV it is installed on), the VNS03 comes with an IR camera for continued operations in nighttime and low visibility conditions. “We’ve also incorporated two new algorithmic features into VNS03. The first enables the use of various types of maps – even outdated or non-professional ones such as freely available online maps – as reference points for UAVs equipped with the VNS to localise themselves. This is achieved by leveraging AI networks that semantically interpret and analyse the content of these maps, allowing the VNS to operate reliably even with imperfect or informal map data,” said Miguel Angel de Frutos of UAV Navigation-Grupo Oesía. Typically, the VNS would require an up-to-date map, such as one generated by a UAV prior to the mission at hand. However, with this new update, Google Maps and other potentially out-of-date sources can be used by UAVs to track their position, find their way and minimise drift during prolonged GNSS outages. “The other new algorithm is TERCOM – our Terrain Contour Matching algorithm,” de Frutos continued. “It uses terrain elevation data from both an onboard AGL sensor and a high-accuracy digital elevation model to enhance navigation performance, even in highly challenging scenarios such as low-altitude, highspeed operations.” The company is also in the final stages of securing a new project, called ‘PNT from LEO’ via the European Space Agency and the Spanish Space Agency, to develop position, navigation and timing (PNT) capabilities using low Earth orbit (LEO) satellites rather than GNSS. It is based on the principle that virtually any LEO satellite transmits and receives signals that can be harnessed for navigation purposes. UAV Navigation-Grupo Oesía notes that such capabilities might be referred to as ‘opportunistic signal navigation’. The company meanwhile continues to expand its customer portfolio, delivering its autopilot and navigation systems to Tier 1 aerospace and defence companies in the USA, Australia, Europe and the UAE. These systems are integrated into a wide range of platforms – from fixedwing aircraft and convertible VTOLs used for surveillance, to advanced loitering munition systems already deployed in real operational environments. Some of these munitions can fly at speeds of up to Mach 0.8 and cover distances of 300 km before striking targets with precision. “As well as delivering autopilots for the Spanish Remote Carrier AUVSI Xponential part one | Show report Uncrewed Systems Technology | August/September 2025 UXV Technologies were among the many companies unveiling new products at Xponential 2025; its Optroxa GMB-450 gimbal bringing numerous advancements over its predecessor Some of UAV Navigation-Grupo Oesia’s autopilot technologies are now controlling munitions that can fly at speeds of up to Mach 0.8 and cover distances of 300 km
