SaVi models Celestri

Multiple satellites, with coordinated movement around a larger mass: a satellite constellation.

I hold two degrees thanks to simulating satellite constellations. I find them more interesting with intersatellite links.

Introductory presentations conducted with live demonstrations using SaVi:

• Constellations - orbital types, uses and advantages, International Workshop on Space and Satellite Communication 2008 (IWSSC '08), Toulouse, October 2008.
• Satellite applications workshop, International Space University, July 2006.

Software:

• SaVi Satellite constellation Visualization.
• ns satellite constellation plot scripts.

Web resources:

• satellite constellations using MPLS.
• rosette constellations - double surface coverage.
• Is O3b embracing polar coverage?
• satellite orbits diagram.
• Lloyd's satellite constellations.

Our work with the CLEO Cisco router in Low Earth Orbit gave experience with the Disaster Monitoring Constellation.
