No images or further information on the satellites was provided. The satellites could be used for purposes related to defense, weather forecasting, and scientific research. These can help verify radar performance, calibration for target detection, weather radar calibration, space debris tracking, or tracking atmospheric phenomena.
Tianping-3 satellites can be used as benchmarks to compare and validate the measurements of ground-based radars, offering highly accurate measurements of their RCS. The satellites may have corner reflectors or transponders on board to provide a strong and well-characterized signal to ground-based radars. This signal helps in calibrating the radar’s performance, such as its power levels, antenna alignment, and other critical parameters.
