Global Ecosystem Dynamics Investigation Science Planning System (GEDI SPS): Tracking and Sampling Performance
Abstract
The Global Ecosystem Dynamics Investigation (GEDI) was launched on December 5th, 2018 and has been collecting operational science data post early orbit checkout since April 18th, 2019. The GEDI Science Operations Center Science Planning System (SOC-SPS) is a component of the GEDI Science and Mission Operations Center (SMOC). The purpose of the GEDI SOC-SPS is to optimize and plan science data collection through the creation of the Science Activity Timeline (SAT) and Reference Ground Track (RGT) files. The SAT and RGT files generated by the SPS algorithms are then modified by specific requests and selections made by the GEDI Science Office (GSO). The resultant SAT and RGT files are then delivered to the MOC to be converted and uploaded as the instrument command load. The SPS file generation is based upon predicted position and pointing for optimal ground sampling. The SOC-SPS uses ISS predicted orbit and pointing files retrieved from Johnson Space Center (JSC) to determine the selection of mission RGTs for every orbit. In addition, the SOC-SPS performs pointing analysis for ISS maneuvers and parks the instrument for invalid attitudes. The SOC-SPS also performs RGT coverage and tracking analysis using science data products created by the Science Data Product System (SDPS). The GSO uses the files from the RGT coverage analysis to further optimize RGT selection. We present science activity planning operational performance, the RGT coverage and tracking analysis process, and the RGT coverage and tracking performance for GEDI.
