Super-Agile: GRB detection capability

Alerts for GRB and other transients: AGILE Fast Link (ORBCOMM)

Super-Agile detection capability for Galactic sources Extragalactic sources

(1) optimal imaging capabilities and large FOV in the energy bands: * 15 keV - 40 keV (Super-Agile) * 30 MeV - 50 GeV (GRID: Tracker+MCAL) (2) Excellent X-ray/ γ -ray timing (GPS) (3) Burst search with large dynamic range (sub-milliseconds-60 seconds) and independent triggering of the Mini-Calorimeter (300 keV-100 MeV). 3 innovative features of AGILE:
