The article presents a developed laser rangefinder-speedometer (LRS) to replace the hand-held laser rangefinders on board transport spacecraft. Using the generalized function of efficiency, the LRFSM characteristics were estimated to show that the LRS has the highest efficiency as compared with existing analogues. As a result of relationship analysis of measuring speed accuracy and reliability of LRS laser source, Pareto sets are obtained, which enable providing the optimal operation conditions of a device. Energy calculations are performed for 5 km range measurements on space complex with a complicated configuration such as the International Space Station. The article considers the use of a geometric factor to protect a photo-detector from the overload when receiving a signal from the nearby angular reflector. The paper presents the results of efficiency evaluation using a generalized function for different types of laser sources that can be used in the LRS.
