Description

Operational analysis of SLR data for precise orbit determination (POD) or for the determination of station coordinates and Earth Orientation Parameters (EOP), should  include known corrections to the range, timing,  or the meteorological measurements (Rodriguez et al., 2023). These corrections account for   known station- and satellite-specific issues in the data, that have been determined by the Analysis Standing Committee (ASC), or through engineering information supplied by the station (Luceri et al., 2019). For some stations, range biases must be estimated (either on a pass-by-pass or an arc-by-arc basis) or data at certain time intervals must be deleted. These corrections must be applied together with a consistent target signature model (Rodriguez et al., 2019). The Data Handling File includes time bias corrections for the SLR stations determined from the analysis of the Jason-2 T2L2 data (Exertier et al., 2017).
