TOKYO (JAX PR) — Mitsubishi Heavy Industries, Ltd. and JAXA successfully launched H-IIA Launch Vehicle No. 37 (H-IIA F37) (with upgraded function) which encapsulates the Global Changing Observation Mission – Climate “SHIKISAI” (GCOM-C) and the Super Low Altitude Test Satellite “TSUBAME” (SLATS) at 10:26:22, 2017 (JST) from the JAXA Tanegashima Space Center.

The launch and flight of H-IIA F37 proceeded as planned. So did the separation of SHIKISAI and TSUBAME, which was confirmed respectively at approximately 16 minutes and 13 seconds and 1 hour and 47 minutes 59 seconds after liftoff.

The reception of telemetry data at the JAXA Mingenew Station, Australia was made at 10:44 a.m. (JST), confirming SHIKISAI’s solar array deployment above Australia. After that, at 11:18 a.m. (JST), the satellite’s attitude control based on its earth sensors was confirmed by telemetry transmitted to the JAXA Santiago Station.

Approximately at 12:54 p.m. (Japan Standard Time, JST), the JAXA Santiago Ground Station, Chile received the signals from TSUBAME (SLATS; Super Low Altitude Satellite). The signal reception confirms that the satellite’s solar array deployment and attitude control based on the onboard sun sensors have occurred as scheduled.

    Didn’t know they had a tracking station in Australia
    Is it used by others?
