2026-08-04 Observation Log doi:10.57760/sciencedb.44713 en This log records several days of satellite laser ranging (SLR) session under clear weather conditions. The table is structured with satellite identification, start time, tracking status, residual parameters, measurement metrics, and for fully recorded passes, additional columns for ranging time, second residual, RMS error, and differential offset. All entries show successful tracking.The dataset comprises multiple ranging attempts spanning several hours. Complete parameter sets were obtained for a subset of targets, indicating valid range measurements. The RMS values fall within a typical precision range for this system, while the DT values remain highly consistent across all fully recorded passes, suggesting a systematic instrumental bias or a common calibration factor. The target list covers various mission types, including navigation constellations, Earth observation platforms, geodesy-dedicated spherical satellites, and scientific small satellites. Multiple revisits to the same objects within short intervals demonstrate rapid retracking capability and highlight the campaign's emphasis on dense temporal sampling for orbit determination or gravity field studies.Overall, this log represents a productive SLR campaign with comprehensive coverage, stable tracking performance, and sufficient complete data records to support precise orbit validation and geodetic research. Minor naming inconsistencies do not affect the scientific utility of the dataset.
