About Experimental Geodetic Satellite "AJISAI" (EGS)
 |
To establish Japan’s geodetic origin through accurate land surveying from space.The primary short-range objective for AJISAI (EGS) was testing of NASDA's H-I'(2-stage) launch vehicle. Long-range applications included a survey aimed at rectifying Japan's domestic geodetic triangular net - determining the exact position of many isolated Japanese islands and establishing Japan's geodetic point of origin.

The Experimental Geodetic Satellite "AJISAI" (EGS)" was launched at 5:45 a.m. on Aug 13, 1986 (JST) from the Tanegashima Space Center and it was put into a circular orbit at an altitude of 1,500 km by the maiden H-I Launch Vehicle. AJISAI is the first Japanese geometric satellite, and its major missions are rectifying Japan's domestic geodetic triangular net -- determining the exact position of many isolated Japanese islands and establishing Japan's geodetic point of origin. AJISAI is a ball-... |
