GeReLEO

Low-Earth-orbit (LEO) satellites require both data links for telemetry, tracking and command (TT&C) and for download of mission data (e.g., Earth observation). A single ground station can maintain a contact to a passing LEO satellite for relatively short time only (typically ~10 min), and together with high-resolution sensor systems onboard the satellites producing high amounts of data this leads to a serious bottleneck. In fact, depending on the actual orbit parameters (altitude and inclination) the long-term average visibility as seen from one ground station is only 1% to 6% of the overall orbit time.
