High Altitude Pseudo Satellite Unmanned Aerial System

High Altitude Pseudo Satellite (HAPS) Unmanned Aerial System (UAS)

PHASA-35® is a novel, ultra-light weight, solar-electric High Altitude Pseudo Satellite (HAPS) Unmanned Aerial System (UAS) which provides an alternative to conventional sensing and communications systems

Pushing the boundaries of aviation technology, PHASA-35 successfully completed a stratospheric flight trial in June 2023, exceeding an altitude of 66,000ft, before landing safely

Designed by BAE Systems’ subsidiary Prismatic Ltd. PHASA-35® is a novel, ultra-light weight, solar-electric High Altitude Pseudo Satellite (HAPS) Unmanned Aerial System (UAS) which provides an alternative and flexible approach to conventional systems such as satellites or conventionally powered aircraft for the provision of persistent and cost-effective imagery and communications

Utilising a range of world-leading technologies including advanced composites, energy management and solar electric cells, photo-voltaic arrays are used to provide energy during the day which is stored in rechargeable cells to maintain flight overnight

PHASA-35 is designed to provide a persistent, stable platform for monitoring, surveillance, communications and security applications. When connected to other technologies and assets, it will provide both military and commercial customers with capabilities that are not currently available from existing air and space platforms. The UAS also has the potential to be used in the delivery of communications networks including 5G, as well as provide other services, such as disaster relief and border protection, at a fraction of the cost of satellites
