Database Design• MCC facilitates online definition of tele

commands and telemetry.• Database design is built upon the

protocol for SSETI Express.• Both data and definitions are stored in

the database.

Conclusion• Platform independent• Providing an easy to use

interface for mission control

• Multiple ground station support (more can be added)

• Abstraction from the satellite communications protocol

• Gathering and processing of satellite telecommands and telemetry

• Suggestion– Data structure

modelling feature– Standard
