Joint photometric observational data from the Kunming Station and Lenghu Station

The dataset comprehensively records the optical radiance and magnitude time series of space targets during the observation period, while also preserving auxiliary information such as observation times, azimuths, instrument parameters, and station coordinates, enabling full traceability between observational data and operational conditions.Compared to single-site observations, this dual-site quasi-synchronous dataset enables effective separation of photometric variations caused by orbital motion, attitude rotation, and surface material scattering through multi-perspective, concurrent photometric differences.

It accurately captures the spatiotemporal evolution patterns of target optical scattering characteristics. Primarily supporting research on attitude state identification and parameter inversion of typical space objects, the dataset features excellent temporal continuity, high spatiotemporal matching accuracy, and strong authenticity of field measurements. It provides solid empirical data foundation for scientific studies including space object attitude characterization, optical observation modeling, and validation, and serves as a robust resource for space target monitoring, feature recognition, and situational awareness.
