ExoAnalytic Solutions SSA Sensor Network TodayGlobal. Persistent. High-Quality. Real-Time.
2
Key features of the ExoAnalytic Global Telescope Network (EGTN) include:• 250+ sensors on 5 continents and Hawaii (~6 hour solar exclusion)• 100% global coverage of GEO, HEO, MEO orbits (>96% availability)• Track near GEO objects as dim as 20th visual magnitude (10 cm @ GEO)• Track near GEO objects with astrometric error 0.1 arcseconds (30 m @ GEO)• Real-time data processing, display and delivery of sensor data (10-30 sec)

ANGELS and Delta IV R/B Photometry versus time
Nightly Persistent Staring at ANGELS
• Dedicated tracking October 2014 – August 2015– 194 scope-nights on ANGELS and its R/B– Typically one scope per night– Sometimes 2 to 3 scopes simultaneous– ~30 different sensors around the globe utilized
• Astrometric accuracy (validated by AFRL)– 0.15 – 0.25 arcseconds (for rocket body)– 0.30 – 0.60 arcseconds (for ANGELS)
Support Description
-
• Full characterization pre, during and post operations– Enhanced safety of flight
• Real-time support until near final docking– Exo orbits
