UAVOS has introduced a new stratospheric Earth-observation payload following a series of successful high-altitude flight tests, marking a significant step forward in high-altitude intelligence, surveillance and reconnaissance capabilities. The newly developed Payload Onboard Device (POD) has been specifically engineered for long-endurance operations in the stratosphere, where conventional unmanned aircraft and satellites often face operational or economic constraints.
The payload was flight-tested onboard the ApusNeo 18 high-altitude platform, a solar-powered aircraft designed to operate in near-space conditions. The tests demonstrated the POD’s ability to deliver high-quality electro-optical and infrared imagery while operating at altitudes of approximately 15,000 metres. According to UAVOS, the system achieved a ground sampling distance of 69 centimetres per pixel for electro-optical imagery and around 4.8 metres per pixel for infrared data, providing detailed situational awareness across wide geographic areas.
Despite its advanced performance, the POD has been designed as a compact and lightweight system, weighing just over 3.5 kilograms. This low mass is critical for stratospheric platforms, where payload efficiency directly influences endurance and coverage. The payload integrates onboard data processing capabilities, reducing the need for raw data transmission and enabling faster delivery of actionable information to ground operators.
A key feature of the system is its high-throughput communications capability. The POD incorporates an onboard computer and a dedicated radio modem with a high-power amplifier, allowing reliable downlink of imagery and sensor data from the stratosphere to ground control stations. This architecture supports real-time or near-real-time monitoring, a crucial requirement for applications such as border surveillance, disaster management, environmental monitoring and infrastructure inspection.
The successful demonstration of this stratospheric Earth-observation payload highlights the growing maturity of high-altitude pseudo-satellite technologies. Positioned between satellites and conventional unmanned aircraft, such platforms offer persistent coverage, flexible tasking and lower operational costs. With this latest development, UAVOS strengthens its position in the emerging high-altitude platform segment, offering scalable solutions for both civil and defence users seeking persistent, high-resolution observation from the stratosphere.
