Introduction

DLR.de • Chart 4

Future Commercial Space Traffic

assumption:

Will return as a hypersonic glider
What does a (Columbia comparable) fatal break

up event (ca. 231000 ft. Alt., speed > Mach 20) mean ?

Debris raining down on conventional air traffic

will cover a footprint of about 300 by 35 nm

No collision of Columbia debris with air traffic

was just luck (Casualty propability for passengers was about 0.3)

SLIDE 5

Provocation

DLR.de • Chart 5

Commercial Space Traffic
Only a few movements per year =

research + entertainment for private super millionaires = no air traffic integration considerations needed = If ever relevant, in the very far future !  Really ?

SLIDE 9

Motivation

DLR.de • Chart 9

SWIM "Intranet for ATM" concept requests all the future air traffic participants acting as communicating sub-systems.

SWIM  What ?

Technical profiles:
Yellow  non critical information
Blue critical information
Purple Air / Ground info exchanges

SWIM  What ?

SLIDE 16

Motivation

DLR.de • Chart 16

Access to real-tjme, relevant aeronautjcal, fmight, and

weather informatjon  faster dedicated response possibilitjes

Reduced implementatjon, operatjng and extension costs

because of SWIM’s standardized character

SWIM = requested fundament of the future for info

based collaboratjon in ATM (Air Traffjc Management)  being prepared for the future

Benefits of acting SWIM compliant

SLIDE 17

Challenge

DLR.de • Chart 17

Safe global space traffic integration by taking into account data distribution of its changing debris (= hazard) area during reentry !

SLIDE 18

Solution

DLR.de • Chart 18

SLIDE 19

Solution using:

DLR.de • Chart 19

TclHttpd as the web server
Web Services for Tcl for the server side web service

creation on top of TclHttpd

TclTLS for using HTTPS
Rpcvar for complex data type definitions
CriTcl for improved performance by the usage of C code

runtime embedding

BaseXClient-Tcl for using the BaseX server protocol to

communicate with the hazard area model database server
