1. 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 Meeting November 16, 1999

2. 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
