Selected Architecture

AOS orbits
Spacecraft: P1 | I1 | I2

Spacecraft acronyms:
  • AOS-P1 - Space Segment Polar
    • 98° inclination (i.e., polar) orbit
    • Sun synchronous
    • 1:30 AM/PM equatorial crossing
  • AOS-I (1 and 2) – Space Segment GPM
    • 65° inclined orbit, similar to GPM (final inclination may be different)
