Objective: The objective of the activity is to develop and demonstrate satellite feeder links that use High Altitude Pseudo-Satellites (HAPS) as an intermediate layer to increase the link's throughput. The activity will develop a test bed to assess the resulting system performance in realistic conditions by emulating critical elements including signal propagation impairments, HAPS payload impairments and constraints, and HAPS platform constraints and dynamics. Targeted Improvements: Doubling the throughput of feeder linksfor a given gateway and satellite antenna size. Description: High altitude pseudo-satellites (HAPS) are solar powered platforms thatare able to fly in the stratosphere over a fixed point uninterruptedly for months. This allows them to act as a relay node in-between the gateways and the satellite. Significant link budget gains are possible that may be traded-off at satellite or ground level. Of particular interest is the reduction of the size and number of ground stations. Hence, this activity will trade-off satellite feeder link architectures that use HAPS as intermediate relay node for geostationary (GSO) and non-geostationary (NGSO) satellite communication systems. Impact to the ground and the space segment will be investigated and the most promising feeder links will be developed in a test bed. The test bed will be able to assess and validate the end-to-end system performance (incl. air interfaces, link andsystem availability) in realistic conditions. As a minimum, this includes emulating signal propagation impairments, HAPS payload impairments and HAPS payload constraints (e.g. power consumption, mass, pointing, acquisition and tracking). It also includes the constraints of power generation, energy storage and propulsion on the aircraft as well as operational conditions such as altitude, attitude, heading, and flight pattern. footnote: On Delegation Request (formerly called Priority 2) activities will only be initiated onthe explicit request of at least one National Delegation.
