Knowledge Exchange

• At GMD FOKUS side SIMTO has established
• research contract with Technical University of
  Berlin (01.04.00 - 31.03.01, 6 month student,
  simulation tool analysis)
• research contract with CNUCE (01.07.00 -
  30.06.01, 12 month scientist, TCP/IP via LEO)
• research stay of GMD researcher in Pisa (6/00,
  2 weeks., introduction into ATM-Sat, agreement on
  workplan)
• research stay of CNUCE researcher in
  Berlin (10/00, 1 week, introduction into
  demonstrator, presentation of results)

• Continuation of SIMTO depends on funding

Work Items Topics

• Network Environment Parameters
• Evaluation of Simulation Tools
• Review of Project Goals
• Simulation Results

5
Network Environment Parameters

• Defined by GMD/Fokus
• Based on LEO Satellite project at GMD
• Includes definition of
• Satellite Orbit
• Bit-Rates
• Bit Error Rates
• Up- Downlink Delay
• Intra-Satellite Delay

6
Satellite Orbit,Bit- Error- Rates
LEO Satellite 1350 km orbit 45deg inclination
Mobil Terminal
Portable Terminal
Service Provider

Propagation Delays

• Up- Downlink Delay
• function of slant range
• analytically gained
• verified with STK

• Intra-Satellite Delay
• routes in the sky still open
• simulation based
• forward backward, left right neighbor
