2 2001-04-052 HomeCarSatellite SIMTO Simulation ToolsSimulation ModelsSimulation Results The SIMTO Idea

3 2001-04-053 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) ð Continuation of SIMTO depends on funding Knowledge Exchange
