Still in the early stage of development, production and operation, High Altitude Pseudo Satellites (HAPS) offers the potential to open a new market for remote sensing and surveillance in the future. HAPS operates at an altitude of approximately 20 km and can observe locations over extended time periods. This enables time critical and continuous monitoring and surveillance over specific areas of interest at relatively low cost.

In the ESA funded project ‘services enabled by HAPS complemented by satellites’, DHI GRAS explores the feasibility and capability of HAPS enabled services to extend the capabilities of satellites and Remotely Piloted Aircraft Systems (RPAS) in the domain of Earth Observation. The main objective is to propose potential services for HAPS that exploit the characteristics of the individual platforms and evaluate the maturity of payload technologies necessary to facilitate service provision.

Through an extensive stakeholder engagement process with potential end-users of HAPS enabled services within maritime operations and surveillance, we established a baseline for a system service definition and payload configuration that addresses the primary technology gaps and service limitations within target user communities. Through this analysis the client gained critical insight into the potential uptake and viability of services enabled by HAPS platforms.
