"KIZUNA" (WINDS) Injection Result to the Drift Orbit
Since the launch on February 23, 2008 (Japan Standard Time, JST) the
Japan Aerospace Exploration Agency (JAXA) has been maneuvering the
KIZUNA (WINDS) to inject it into its drift orbit by firing the apogee
engine and 20N thruster.
As a result of the orbit calculation after the 20N thruster firing, we
have confirmed that the KIZUNA was injected into its scheduled drift
orbit as follows.
Result * Schedule *
Apogee altitude 35,824 km (35,822 km)
Perigee altitude 35,192 km (35,222 km)
Orbit inclination 0.08 deg (0.09 deg)
Period 23 hr and 41 min (23 hr and 42 min)
Drift rate 3.6 deg/day East (3.4 deg/day East)
* Decimal fractions are rounded off.
The satellite is in good health.
We plan to start deploying the Multi-beam antennas (MBA) at around
12:47 p.m. on March 1 (JST [0347 UTC]) The result of the deployment
is scheduled to be announced at 4:30 p.m. on March 1 (JST [0730 UTC]).
NOTES
Transfer orbit:
A temporary orbit for a satellite between the launched orbit and its
final orbit. After being launched and injected into a transfer orbit
by the launch vehicle, the satellite is gradually maneuvered and
injected into its final orbit.
Drift orbit:
The last step orbit prior to the geostationary orbit. A circular orbit
whose altitude is about 36,000 km.
Drift rate:
The speed of a satellite moving in a longitudinal direction when
looking at it from the Earth
Multi-beam Antenna (MBA):
An antenna that can form a multiple number of beams
