AGILE
2007-013A
AGILE (Astrorivelatore Gamma ad Imagini Leggero, Light Gamma-Ray Imaging Astronomical Detector) was developed for ASI using Carlo Gavazzi Space Spa/Milano MITA bus and CGS project management. PSLV to 550 x 550 x 6 deg, mass 352 kg. Perigee was a little low (523 km instead of 550 km).
PSLV modified to carry light payload; no PSOM and 400 kg of prop offloaded from the PS4 stage.
Sensitivity less than EGRET on-axis, but much better off-axis performance. 2.5 sr FOV. GRID has 5' to 20' resolution. The GRID MC (MiniCalorimeter) will also detect bursts in the 0.3-200 MeV range and Super-AGILE will give simultaneous hard X-ray data.
The AGILE (Light Imager for Gamma Astrophysics)
Launched with PSLV Advanced Avionics Module (180 kg) inside the Dual Launch Adapter.
SUPER AGILE 4 x 1D coded masks bibcode NIM-A 581, 728F Feroci et al 2007 45 sources seen to date, mostly XBs, some AGN, 2 GRB
In 2009 the reaction wheel malfunctioned, ending AGILE's ability to point at targets. Following this, AGILE was spun around the sun-pointing axis at 1 degree per second, surveying 70 percent of the sky each day.
