Description
Summary:The goal of near real-time delivery of data from spacecraft in polar low Earth orbits to the customers can be achieved by utilization of Arctic and Antarctic hubs in a Ground Station Network. Additionally, the commanding of the satellites from these hubs can provide novel opportunities for spacecraft operations. The challenge of high-rate data repatriation from such remote sites can be met by means of laser communications from ground to geostationary satellites. We present system architecture and operations concept for a setup employing the European Data Relay System (EDRS) for data uplinks from an Antarctic ground station taking into account the impact of local atmospheric conditions.
