HISAKI (SPRINT-A)
Orbit Calculation Result and
Critical Operation Period Completion
September 15, 2013 (JST)
Japan Aerospace Exploration Agency (JAXA)
The Japan Aerospace Exploration Agency (JAXA) confirmed that the Spectroscopic Planet Observatory for Recognition of Interaction of Atmosphere "HISAKI" (SPRINT-A) was injected into the planned orbit after its orbit calculation as follows.
Orbit Calculation Result
| Actual value | Planned value | |
| Apogee altitude | 1156.8 km | 1150 km |
| Perigee altitude | 946.8 km | 950 km |
| Inclination | 29.7 deg | 30 deg |
| Period | 106.2 min | 106 min |
We have now completed the critical operation period for the HISAKI (SPRINT-A) after we successfully performed essential events including the planned orbit insertion, solar array paddle deployment, and sun acquisition.
JAXA will take about two months to further confirm the status of the HISAKI (SPRINT-A) such as verifying the high-precision attitude control function that is imperative for planet observations.
We would like to express our sincere appreciation to all the parties and personnel concerned for their support and cooperation with the HISAKI (SPRINT-A) launch and tracking control operations.
