SSA Environmental Effects Fusion System (SEEFS)

•SEEFS merges environmental data with space system parameters to specify effects on ground & space assets

AFRL’s Opinion

SupraThermal Electron, Ion, Neutral Experiment STEIN (AFRL-0903)

PI (or PM): Chin S. Lin, AFRL/RVBXI

Technical Problem: Current charged particle detectors are too large and heavy for nano-satellites

Military Relevance: • Allow warfighters to distinguish

environmental effects from hostile threats

– Accurate anomaly root cause analysis

Hardware Status:• Current Technology Readiness Level: 6• Flight Unit: 4th quarter FY11• Flight Ready: 2nd quarter FY12• New advanced technology developed by

Univ. of California at Berkeley

Size: 10x10X15 cmWeight: 1.5 kg Power: 1 W

Distribution Statement D: "Distribution to US Government Agencies and Authorized DoD Contractors only; Administrative or Operational Use; 11 October 2005. Other Requests for this document shall be referred AFRL/RVBXI.

•Leverages new miniature solid state detector•Built and tested sensors, prototype, & components

44

Plasma Drift, Particles And Ion Density

• Low Energy ElectroStatic Analyzer (LEESA-2):• Electrostatic analyzer adapted to a high inclination orbit. Measures

energies 30eV - 50 keV. 4U size.

• Provides accurate determination of auroral boundaries and particle energy input. Heritage instrument: SSJ5 on DMSP

• Ion Velocity Meter (IVM):• Consists of a Retarding Potential Analyzer (RPA) and an Ion Drift

Meter (IDM). Heritage instrument is flying on DMSP and C/NOFS.

• Planar Langmuir Probe• Ion density

• Density fluctuation

• Heritage: C/NOFS

IVM

45

Doppler Asymmetric Spatial Heterodyne (DASH)

• DASH is a sensor to remotely measure the thermospheric wind• Funded in part by NRL, in part by AFRL• Heritage: similar instrument on a Space Shuttle mission

DMSP Recent Successes

• Identified & fixed F19 OLS performance degradation • Anomaly: OLS Dark Noise Factory Test out of limits during 8 Oct 09 test• Root Cause: Identified Apr 10; metal-metal corrosion created resistance• Corrective Action: Completed fix & system level re-test 20 Apr 10 (results nominal)

• F19 OLS Flight Unit delivery to LM planned for 20 Aug 10

Variability due to test conditions

Performance returned to post-ATP conditions

DMSG Successes

• Successfully completed DMSP F20 Early Power Turn On Testing -- first tests in 14 years!

• Identified and fixed F19 OLS performance degradation--return to ATP performance

• Successful F15 Gyroless Yaw Estimator Test--extends DMSP mission life

• Earth Sensor Assembly Bias Estimate Improvement--solves lens fogging issue

• Completed SSAEM's Alternatives Analysis--most cost-effective concept established

• Conducted MDA Program Status Meeting & Concept Recommendation

• SSAEM Sensor Modernization Source Selection in progress and on-track for August awards

• C/NOFS Team discovered that scintillation occurs not only between dusk and midnight --but

also midnight to dawn

• Completed formal Development Test as part of JSpOC Mission System (JMS)

•  Identified and corrected system errors which led to major component failures in the solar

observatory antenna pedestal gearboxes 

• Identified and coordinated a new MKIVB in-theater location for CENTCOM at Ali Al Salem

• Completed four NEXION installs and the fifth one is going in at Goose Bay this month

DMSG Commander’s Priorities

• Readiness – ORI and UCI• Program Execution - cost, schedule, performance • Program Extension - moving launch dates out, contractual

processes• F19 Sensor deliveries and integration

• Resolution of oscillation reach back• F19 OLS + SSMIS Fixes

• SSAEM program startup• DWSS and organizational transition

• Tiger teams at work• ADM in coordination

• DWSS and SSAEM space allocation• Wing/Group/Squadron Transition

52

DMSG Commander’s Summary

• It’s ‘Not Just the Weather’• It’s a lot tougher than it looks• Architecture in its infancy• DoD understands importance…….• BUT the priority is relatively low• Sensors are good……..• BUT the infrastructure must be sound• Many possible paths for the future• Is there money in it???
