I-RIA Novosti ibika ukuthi ekupheleni kweminyaka eyishumi ezayo, iRussia ihlela ukuthumela iqembu elisha lezindiza-mkhathi ze-geodetic.
Uhlelo lwe-Geo-IK-3 luyintuthuko eyengeziwe yesathelayithi ye-Geo-IK-2. Lolu lwakamuva luklanyelwe ukwakha inethiwekhi ye-geodetic enembayo kakhulu ohlelweni lwe-geocentric coordinate, kanye nokuxazulula izinhlelo zokusebenza eziningi ezidinga ukunqunywa okusheshayo kwezixhumanisi zamaphuzu omhlaba.
Ukwethulwa kwe-Geo-IK-2 spacecraft yokuqala, okwenziwe mhla lu-1 kuNhlolanja 2011, kwaphela ngengozi: isathelayithi yafakwa endaweni engahlosiwe ngenxa yamaphutha esigabeni esiphezulu. I-spacecraft yesibili neyesithathu emndenini yethulwe ngempumelelo mhla lu-4 kuNhlangulana 2016, kanye nangomhla zingama-30 kuNcwaba 2019.
Iqoqo lezinkanyezi i-Geo-IK-3 lizohlanganisa amasathelayithi amahlanu. Lawa ahlanganisa amasathelayithi amabili e-altimetry, alinganisa ukuphakama kobuso boMhlaba. Azokhishwa angene emkhathini ngo-2027 nango-2029.
Ngaphezu kwalokho, uhlelo lwe-Geo-IK-3 luhlelwe ukuthi lufake isathelayithi eyodwa ye-gradiometry (ukunquma i-gravity gravity) kanye namasathelayithi amabili e-gravimetry (ukulinganisa ubuningi obuchaza insimu yamandla adonsela phansi yoMhlaba). Ukwethulwa kwazo zonke lezi sathelayithi kuhlelelwe okwesikhashana ngo-2028.
