Camera Systems

The ER-2 can carry a variety of film camera systems, and the C-130 is equipped with two cameras. Most of the cameras and lenses are routinely calibrated for precision photogrammetry, and numerous film types are in use.


Type Lens Film Format Ground Coverage Nominal Resolution Scale
RC-10 6"/f4 9" X 9" 30 X 30km (16x16 nmi) 3-8m 1:130,000
RC-10 12"/f4 9" X 9" 15 X 15km (8x8 nmi) 1.5-4m 1:65,000
HR-732 24"/f8 9" X 18" 7.4 X 15km (4x8 nmi) 0.6-3m 1:32,500
IRIS (Panoramic) 24"/f3.5 4.5" X 35" 3.7 X 40km (2.0 x 21.4 nmi) 0.3-2m (Nadir) 1:32,500

Note: Spatial parameters are for the ER-2 at 19.8km (65,000 feet) altitude.

Missions are typically flown with 60% forward frame overlap for stereo coverage.
