Spaceborne Architecture
Spacecraft: AOS-P1 | AOS-I1 | AOS-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
- 55° inclined orbit, similar to GPM (final inclination may be different)
International contributions are marked with flags. Other elements will be provided by NASA/US. Information regarding other candidate architectures considered for this mission.
