- Proposal of SS/Loral, Qualcomm, Alcatel - other partners, e.g. Vodafone
- 56 satellite constellation in 8 planes
- ~1,400 km inclined LEO orbit
- Transparent transponder
- no cross-linking
Let's look at a third proposal. This is something of a halfway house between Iridium and ICO
- 48 operational satellites with 8 spares (1 per plane). Each satellite weighs 450 kg and
has a total transponder power of 1 kW. Lifetime is 7.5 years.
Globalstar (2) - Network
Key point... transparent transponders and no crosslink ISLs.
Globalstar (3) - CDMA Soft Handover / Redundancy
CDMA... signals relayed through more than one satellite at a time... blockage and handover
Globalstar (4) - Coverage
Coverage resembles ICO but more satellites and much lower so more complex.
