GRABIT is the gamma-ray bar imaging telescope, a low-energy gamma-ray (60-600 keV) imaging spectrometer that can be extended to a large area at low cost. GRABIT has a gamma-ray position-resolution of 2 mm with an energy resolution typical of alkali-halide detectors (18% at 60 keV). The complete coded-aperture telescope will have arc-minute angular resolution over a large field of view. In addition, the good energy and angular resolutions are obtained over the full bandwidth of the instrument
