• Mission Operations– Launch February 15, 2000 at 22:02:15 UTC = 14:02:15 PST– 41 Days IOC and antenna deployment period– 2 year science mission operations

• Orbit– Inclination 90 degrees– Perigee 1000 km (initially)– Apogee target altitude 7.2 Earth Radii = 45,923 km– Orbit Period 14.25 hours– Initial argument of perigee 320 deg., precesses 79.95 deg. in 2 years– Ascending node at 180 deg. Right Ascension, constant.– Precession of perigee and local time determine location of IMAGE in

magnetosphere

Jim Burch’s presentation at IMAGE Team MeetingNovember 16, 1999

• Apogee altitude

– Desired: +/-1600 km

– Delta 3rd Stage capability: +/-2500 km

– Science Team Has agreed to +/- 2500km

• Inclination +/- 1 degree

• Eccentricy +/- 0.05

– Function of Apogee Altitude Uncertainty

• Ascending node: +/- 15 degrees

– Drives launch window width (one hour per day)

– Affects minimum sun angle from z-axis:

• Thermal, power, and navigation systems designed for 23.5 degrees or more sun angle from z-axis

• Argument of Perigee: +/- 3 degrees

IMAGE ELV Configurationand Mission Characteristics
