Latè-lalin espas satelit lazè distans la se byen lwen, ak pandan lajounen an, ki anba enfliyans a limyè solèy la, siyal la retounen reflete nan sou-tablo lazè reflektè a se fasil submerged nan bri a background fò, ki se difisil yo dwe rekonèt . nan tan sa a, yon 3 jou sa a, yo ka pote soti nan lannwit lan. "Tendu-1" TDT test star successfully carried out the Earth-Moon space satellite laser ranging technology test under the condition of strong light interference during the daytime, which is the first time in the world that satellite laser ranging is realized on the new generation of Earth-Moon space laser corner reflector during the daytime, and it marks that our country has made a new technological breakthrough in the field of deep-space Orbital mezi presizyon .
Shanghai Obsèvatwa astwonomik nan Akademi Chinwa a nan Syans (ki refere yo kòm Shanghai Obsèvatwa astwonomik) te devlope yon nouvo jenerasyon nan Latè-lalin espas lazè Corner Reflector pou "Tiandu -1, ki Peze Sèlman 1 {{{ Siksè nan lajounen satelit lazè tès la nan espas Latè-lalin.
Cheng Zhi'en, senior engineer in charge of the reflector project, said that the new-generation Earth-Moon space laser angular reflector is like a super-strong reflective "mirror" to ensure that the laser signals can be efficiently returned to the ground in the original way of the laser station, which has the advantages of strong reflective ability, high precision, lightweight, etc. The success of this test is the result of the Efò konjwen nan tout pati yo . Siksè nan tès sa a se rezilta nan efò yo konjwen nan tout pati yo, ki endike ke pèfòmans nan konplè nan pwòp tèt ou-devlope Lachin nan nouvo jenerasyon nan Latè-lalin espas lazè Reflector te rive nan nivo entènasyonal la, ki pral fòtman sipòte eksplorasyon Lachin nan sou latè espas ak espas gwo twou san fon {{{

The Shanghai Observatory also utilized the ground-based orbit measurement data to form a high-precision orbit forecast of the "Tiandu-1" satellite, which was used to guide the laser observatory to accurately track and target the satellite, a key part of the success of this experiment. Researcher Huang Yong, head of the Shanghai Observatory's Satellite Laser Sòti ak gwoup aplikasyon an, te di ke lazè ki gen anpil presizyon ki ka amelyore presizyon nan òbit nan sond espas Latè-lalin ak gen gwo potansyèl pou aplikasyon pou syantifik ak jeni .
Deep Space Exploration Laboratory "Tiandu No. 1" general responsible person in charge of the overall conductivity technology test star introduction, the smooth implementation of the daytime strong light interference conditions of the Earth-Moon space satellite laser ranging test, effectively expanding the observation window of the technology, will be a strong support for the international lunar research station and other deep space exploration of the major engineering tasks demonstration and Aplikasyon .
The technology test was led and organized by the Deep Space Exploration Laboratory (DSEL), with the Shanghai Astronomical Observatory of the Chinese Academy of Sciences (CAS) being responsible for the development of the on-board laser angular reflector and the satellite's precision orbit prediction, and with the participation of the Shanghai Satellite Engineering Research Institute (SSERI), Yunnan Astronomical Observatory of the CAS (YAO), Sun Yat-sen University (SYSU), ak Beijing Aerospace Control Center a (BAAC) .
