Jim Burchs presentation at IMAGE Team
Meeting November 16, 1999

• Mission Operations
• Launch February 15, 2000 at 220215 UTC
  140215 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

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

• Launch Site SLC-2W at VAFB
• Launch Period February 15 thru March 10,
• 2000 based on current trajectory analysis
• Liftoff time (hrminsec PST)
• 15 Feb 00 140215
• Orbit Requirements
