HALO-I is an airborne observatory that offers excellent
performance, adaptability, and endurance for its mission.
The capability to fly at very high altitude, above
obscuring clouds and atmosphere, provides the HALO-I
sensors a clear view of mission targets. The large
windows on the Gulfstream aircraft (replaced with optical
windows) and enclosed, environmentally controlled optical
benches make this aircraft an excellent choice for
unique and experimental EO/IR systems.
