GRID is an advanced backpack with a radiation detection, identification, and source localisation system enclosed. The detector system is lightweight (4.9 kg), and fits in a small, inconspicuous backpack.
The GRID Backpack is compatible with DARPA’s SIGMA Network when paired with a specialised app on an Android phone. Using SIGMA’s web-based user interface, multiple units can be easily tracked, displaying threats at multiple locations in real-time on the map of a specific area at a remote and centralised location allowing analysis by experts trained in radionuclide identification.
