Changchun Tib Neeg Satellite Observatory Ua tiav Kev Tshawb Fawb Txog Kev Ntsuas Ntsuas Qhov Ntsuas Ntawm Jilin 1.2m Ze-Infrared Non-cooperative Target Laser Ranging Platform

Thaum Lub Ib Hlis 28, 2024, Changchun Artificial Satellite Observatory (CASO), Changchun Institute of Optical Precision Machinery thiab Physics (CIPMP), thiab Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Qhov Chaw (ISI) tau sib koom ua qhov kev sim ua pov thawj ntawm txwv kev txheeb xyuas qhov ntsuas ntawm cov hom phiaj tsis koom tes ntawm qhov tsim kho tshiab 1.2m ze-infrared laser ntau yam platform hauv Jilin, thiab ua tiav tau qhov tsis muaj zog laser sib txawv echoes ntawm lub hom phiaj tsis koom tes (NORAD No.: 00900). Tom qab ua tiav, cov ntaub ntawv zoo arc ntev yog 1 feeb thiab 15 vib nas this, tus naj npawb ntawm cov ntaub ntawv siv tau zoo yog 47, thiab qhov tsawg kawg nkaus ntawm qhov sib npaug 1000km lub hom phiaj yog 0.1174m, uas ua tau raws li qhov yuav tsum tau muaj ntawm laser kuaj pom qhov txwv tsis pub muaj -kev sib koom tes lub hom phiaj ntawm 1.2m ze-infrared laser ranging system, thiab kev sim validation ntawm qhov txwv kev ntsuas qhov ntsuas tau ua tiav tiav.
NORAD No. 00900 lub hom phiaj launched thaum Lub Kaum Hli 1964, US Air Force microsatellite (radar calibration ball), lub npe CALSPHERE 1. Lub hom phiaj yog txoj kab uas hla ntawm 14 ntiv tes (35.6cm) ntawm polished aluminium hollow kheej kheej, huab hwm coj ntawm 0.98kg (lub hom phiaj ntawm cov ntaub ntawv qhov chaw: Siegfried W. Janson, "Micro /" Nanotecnology rau Picicosat. Nanotecnology rau Picosatellites"), uas yog tsim los rau lub polar orbit ntawm qhov siab ntawm 1000 km, tau siv los ua ib qho Lub hom phiaj radar thiab raws li lub hom phiaj calibration rau Atmospheric Density Monitor (ADM), qhov twg cov ntaub ntawv orbit taug qab tuaj yeem siv los txiav txim siab qib satellite, thiab yog li kev sib raug zoo ntawm atmospheric ntom ntom thiab qhov siab, huab cua nyob rau hnub ntawd zoo, thiab lub hom phiaj tau pom nyob rau hauv lub koob yees duab luv luv qhia lub hnub qub. Lub sijhawm soj ntsuam yog los ntawm 10: 55 txog 1: 59 UTC thaum Lub Ib Hlis 28, 2024, thiab lub suab siab tshaj plaws ntawm lub hom phiaj hauv kev soj ntsuam arc yog 63.5 degree , thiab Qhov tsawg kawg nkaus pom lub kaum sab xis yog 21.7 degree.
Kev tshawb pom ntawm cov hom phiaj me me uas tsis muaj kev koom tes tso rau pem hauv ntej cov kev xav tau siab heev thiab cov teeb meem loj rau kev soj ntsuam lub koob yees duab thiab taw qhia qhov tseeb ntawm cov kab ke sib txawv, qhov kev tshawb pom ib leeg-photon rhiab heev ntawm lub ntes, qhov kev ncua deb ntawm lub sijhawm raug, kev saib xyuas thiab taug qab. ntawm qhov tsaus ntuj thiab tsis muaj zog qhov chaw khib nyiab lub hom phiaj, lub teeb pom kev zoo ntawm lub laser nrog rau transceiver-optical axis parallelism, thiab lwm yam. Tam sim no, Tuam Tshoj tau siv zog heev hauv qhov tseem ceeb ntawm daim ntawv thov ntawm lub tsom iav raj. Tam sim no, Tuam Tshoj ua qhov chaw khib nyiab soj ntsuam ntawm qhov tseem ceeb hauv-orbit daim ntawv thov satellites, thiab muaj qhov xav tau ceev los tsim kom muaj qhov tseeb qhov chaw khib nyiab soj ntsuam hauv Suav teb. Changchun Human Health chaw nres tsheb, koom tes nrog Changchun lub koom haum ntawm Optical Mechanics thiab Space Academy, tau sib koom ua ke kev tsim kho ntawm 1.2m ze-infrared laser ntau yam platform system deployed nyob rau hauv Jilin. Cov pab pawg tsim kho muab kev ua si tag nrho rau lawv cov kev ua tau zoo thiab kev ua haujlwm ntev ntev hauv kev tsim kho lub koob yees duab, kev tswj hwm software thiab kho vajtse, kev sib koom tes tsis yog lub hom phiaj, kev loj hlob laser loj thiab lwm yam kev siv tshuab. Lub 1.2m ze-infrared laser rangeing system ua tiav thaum Lub Xya Hli 2023 tau dhau qhov kev sim tag nrho thiab kev ntsuam xyuas ntawm lub kaw lus, thiab tam sim no nyob rau theem pib ua haujlwm ntawm lub kaw lus. Qhov kev ua tiav ntawm qhov ntsuas qhov txwv no tau lees paub tag nrho lub peev xwm kuaj pom lub peev xwm ntawm 1.2m ze-infrared laser ranging system tsim los ntawm lub koom haum rau me me tsaus nti thiab tsis muaj zog cov hom phiaj uas tsis muaj kev koom tes, uas yog qhov tseem ceeb rau kev tsim kho hauv av. -raws li high-precision laser saib xyuas network rau qhov chaw khib nyiab hauv Suav teb thiab tseem yuav ua lub luag haujlwm zoo hauv kev txhawb nqa kev tshawb fawb ntawm high-precision orbital cataloging ntawm qhov chaw khib nyiab lub hom phiaj nyob rau hauv qis-orbit, ceeb toom ntxov ntawm kev sib tsoo thiab kev txiav txim siab precision orbit.
