Laser ranging is a kind of high precise measuring technology for spacecraft orbit determination. The traditional laser ranging is to measure the roundtrip flight time of laser pulse to collect precise measurement of range that allows the spacecraft to achieve its requirement for precise orbit determination. For the long distance spacecrafts farther than the moon, the above measuring way is not suitable and the one-way range measurement via laser pulse time-of-flight from ground stations to spacecrafts should be utilized. For this measuring mode, the laser signal energy falls off only as square of distance and the laser signal can reach the place beyond the moon to the planets. The one way laser measurement will become a significant way for interplanetary laser ranging. By using the ground satellite laser ranging system, laser measuring experiments to geosynchronous satellite equipping laser detector and timing counter are successfully implemented. The comparison and analysis for laser data obtained from both the one way and the roundtrip flight measurements are carried out. The measuring results validate the feasibility of one way laser ranging. The measuring experiments provides reference for further study on the one-way laser ranging and design of laser measuring terminal system for interplanetary spacecraft in future.
