Superconducting single photon detection technology can achieve extremely weak light reception at the photon level,which is one of the key technologies for deep space detection to achieve ultra-long distance reception.However, the pulse jitter effect caused by photon probability distribution deteriorates communication and ranging performance.In this paper,we design a single photon laser communication ranging integrated system based on pulse position modulation (PPM)modulation.A novel PPM waveform with compressed pulse width is proposed based on the distribution characteristics of photons,which can reduce the impact of pulse jitter on communication reliability and ranging accuracy. Meanwhile,prototypes of satellite and ground terminals are developed,and a bidirectional communication and synchronous forwarding distance measurement verification platform is built.The experimental verification results demonstrate that under the same receiving power(-53.2 dBm)conditions,when using a 1/4 pulse width compression ratio,the communication reception error rate decreases from 4.7×10-⁴to 5×10-¹,and the ranging accuracy increases from 23.61 cm to 0.91 cm,achieving highly reliable communication transmission and high-precision distance measurement.
