QX06 satellite laser terminal in orbit 2024 in orbit chain building pointing error dataset

This data aims to analyze the pointing error during the in orbit chain building process of QX06 satellite, in order to facilitate subsequent optimization. The data is sourced from the chain building process of QX06 and QX05 on the same orbital plane between May 2 and May 8, 2024, as well as the chain building process of QX06 and QX03 on the opposite orbital plane between November 5 and November 9, 2024. The data is transmitted to the ground through wide beam transmission via on-board engineering data. The raw data is processed using Excel to remove outliers and missing values, which are either lost or erroneous during the up and down transmission of the data. The dataset is divided into date, chain building status, and pointing error according to table columns, with a sampling rate of 1 second per time for date information; Chain building status: 0 indicates scanning/staring process, 1 indicates coarse tracking, 2 indicates successful chain building; The pointing error is obtained by processing the theoretical and actual positions of the terminal azimuth and elevation motors, in mrad units.
