UAVOS Introduces Stratospheric Earth Observation Payload Following Successful Flight Tests

UAVOS announces the successful flight testing of its optoelectronic, gyro stabilized Payload Onboard Device (POD) integrated into the HAPS ApusNeo 18, a solar powered high altitude pseudo satellite developed as part of joint project with Mira Aerospace. Using steerable high-resolution cameras, the system demonstrated coverage of 472 km of electro optical imagery with a ground sampling distance of 69 cm per pixel, as well as infrared imagery at 480 cm per pixel, from an altitude of 15,000 m. The camera's footprint covered 53.9 km², while its steerability allowed access to any point within a 54,5 x 12,3 km area at any time. Designed specifically for stratospheric operations, the POD significantly enhances the intelligence, surveillance and reconnaissance capabilities of HAPS platforms.

The POD weighs 3.6 kg and features a compact form factor measuring 845 mm (length) × 128 mm (width) × 142 mm (height). It is equipped with an onboard computer for data processing and a UAVOS radio modem with a 10 W amplifier, enabling high throughput data transmission to the ground control station.

To ensure reliable high-altitude performance, the POD incorporates an integrated heating and cooling system that maintains optimal operating conditions for onboard sensors. It also includes a foldable, servo driven antenna that can be stowed in a safe position when required. Additionally, the mechanical design enables video and photo acquisition with roll stabilization of up to ±50 degrees, expanding operational flexibility and imaging performance.
