- Data routing and transmission protocols
DARPA Fractionated Spacecraft workshop,
Colorado Springs, 3-4 August 2006.
With thanks to Will Ivancic.
Note: Pass figures are rounded approximations. It's actually a 12 minute pass * 8140800bps = 715MB, or just over 650MB (a CD-ROM's worth) that can be downloaded each pass once framing overheads are taken into account.
Data routing and transmission protocols (3.9M)
- Satellite applications workshop
As a guest lecturer, gave a three-hour workshop at the International Space University summer session '06 in Strasbourg, France, 12 July 2006 (via Bill Cowley). Introduced satellite constellations, then let students work on simple exercises in creating constellations using SaVi. Also spoke on slot clouds and on CLEO.
Work done on SaVi for this workshop led to the release of SaVi 1.3 (diary entry). Uses ns satellite constellation plot scripts.
See also later constellations tutorial.
Introduction to satellite constellations (4.1M)
ISU student introduction to SaVi (309K), which became the SaVi user manual.

- Testing the Cisco router in orbit: thoughts on extending the Internet into space
A talk on Cisco's router in orbit given as part of the local Guest Lecture Series (via Tanya Vladimirova), Surrey Space Centre, Tuesday 15 November 2005.
A commercial mobile router was integrated into the UK-DMC satellite, and has been on orbit with the satellite for over two years. The talk overviews over a year of successful testing of the router, along with the developments in extending the Internet to orbit and building Internet-Protocol-enabled satellite infrastructure that made this router integration possible (and even easy) in the first place. Possible future steps are also discussed.
Testing the Cisco router in orbit slides, presented Tuesday, 15 November 2005.
