Abstract

It is a meaningful issue on how to download remote sensing data to the ground stations through data relay satellites efficiently. Taking the priority of tasks, the success rate, the utilisation of bandwidth and time window constraints into consideration, this work proposes an efficient real-time scheduling and proactive data download algorithm for the data download task of Earth Observation Satellites. The NP-hard problem of scheduling between multi satellites with lots of tasks is transformed into individual satellite dynamical scheduling. To make a convincing argument, we perform several experiments to compare the proposed ERS-PDD algorithm with FCFS, EDF, LPTF and SRTF. These experiments show our ERS-PDD algorithm performs better in success rate and the number of permitted tasks.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
