New Horizons Case study of the New Horizons Mission to Pluto Launch: Jan. 19, 2006 Pluto Encounter: 2015
Pros of Decentralized Approach • Each instrument team is autonomous in the choice of their test and development system. • Potential re-use of existing test equipment and familiarity with existing development tools. • Administrative and budget structure often supports/dictates splitting the responsibilities at ICD level.
Cons of Decentralized Approach • Duplication of interface implementation effort. • Payload integration has to account for interface problems. • TLM&CMD changes are not adopted quickly and concurrently by instrument teams • Higher level test tools like STOL (Spacecraft Test and Operations Language) are usually not feasible to develop on instrument level • Little or no cross-instrument data visibility
Coordinated GSE • Reduced mission wide development effort • Payload integration can be performed more efficiently • High level test environments like STOL interpreters are feasible • Telemetry and command databases can be converted into GSE configuration • The instrument customization can be reused through bench testing, payload integration, and flight operations • Cross-team data access • Compact hardware configuration. One PC can run all instrument GSEs simultaneously
GSEOS • Rapid Development Tool for GSE • Quick Look System • Simple bit level telemetry definition • Dynamic data modeling with custom decoders • Archiving/Playback • STOL Emulator • Version Control • Extremely portable
New Horizons GSE • ExcelTM based TLM & CMD definitions • Zero-Impact Conversion Tools • STOL Emulator • Common MOC (Mission Operation Control) Interface • Configuration Control • Cross-team Telemetry Visibility
Mission Benefits • Enhanced GSE capabilities • Reduced code duplication (20%) • Reduced technical risk (30%) • Reduced scheduling risk (50%) • Reduced hardware costs (50%) • Reduced overall mission costs
