Institute of Seismology, China Earthquake Administration has developed a new generation of large-aperture mobile satellite laser ranging system TROS1000, which uses a convenient transport structure, a picosecond kHz semiconductor laser, a self-developed picosecond event timer and a nanosecond range gate generator, in order to solve the unbalanced distribution of satellite laser ranging stations in the East and West of China. TROS1000 is the kilohertz satellite laser ranging system, it can be transport conveniently and setup quickly. In september 2019, TROS1000 arrived at Nanshan station of Xinjiang Astronomical Observatory, Chinese Academy of Sciences. TROS1000 acquire kHz satellite laser ranging observation data in Western China for the first time. After data preprocessing, the single accuracy of low earth orbit and medium earth orbit satellites are better than 14 mm, that of high earth orbit satellites are better than 19 mm. Compared with the previous mobile satellite laser ranging system, TROS1000 has higher single accuracy, more valid echo signals and stronger target detection capability.
