摘要：
Unified laser TT&C system can achieve duplex high speed communication, high precision range measurement and clock synchronization between two terminals simultaneously. To achieve the unified laser TT&C system, a prototype of laser communication system was developed based on on-off keying (OOK) and realized to simulate the space terminals. It was arranged with two set simulation terminals, used to send laser modulated signal separately, record the transmitting and arriving time of data frames, and based on the data to calculate the range, time transfer error and frequency transfer error of the measurement results. The terminals were linked via single-mode fibers with length of about 22 km. Along with the duplex laser communication demonstration with data rate of 2.5 Gbit/s, the high measurement precision can achieve 6.2 mm for ranging random error, 1.3 mm for ranging systematic error, 27 ps for time transfer error, 2.7×10-13 for frequency transfer error. The prototype provides a technical base for the development and upgrade of the unified laser TT&C equipment in the future. © 2020, Editorial Department of Transaction of Beijing Institute of Technology.
