ASTOS vs. in‑house and other tools
|
Criteria |
ASTOS |
In‑house / other tools |
|
Spaceflight scenarios |
All (launchers, constellations, exploration, re‑entry) |
Narrow domain (e.g., only launchers or only satellites) |
|
Coding needed? |
Zero – fully data‑driven (XML/GUI) + Simulink |
Often requires custom MATLAB/Python scripts |
|
Validation |
TRL9, 20+ years, used on real European missions |
Limited to internal projects, no independent validation |
|
PIL/HIL ready |
Yes – native dSPACE SCALEXIO integration |
Rare – requires custom integration work |
|
Support in Japan |
Local support by Orbspace (Japanese, on‑site/remote) |
None or limited, English only |
|
Cost / risk |
Affordable license, free trial, startup/academic discounts |
High license cost; months of development, knowledge loss if staff leaves |
Trusted by industry & agencies worldwide
Used on numerous missions in European and worldwide – 20+ years of flight heritage.
Local support in Japan 
Orbspace Corp. (Tsukuba) provides full Japanese‑language support, on‑site training, and remote assistance.
