ALI and Hyperion Ground Tracks (9.6 KM) ALI SCA-4 N Hyperion (7.7 KM) 4 3 2 1 (37 KM) EO-1 ALI EO-1 Hyperion (7.7 KM) The Advanced Land Imager (ALI) is comprised of four Sensor Chip Assemblies (SCAs).
EO-1 Lunar Calibration Sequence December 2000 – December 2011 • Lunar Cal’s have been performed monthly, with both ALI and Hyperion powered-on, at a +7.4° from full lunar phase angle. • The lunar disk is an approximately (½)° object at EO-1’s orbital location. This fits within the viewing angle of the Hyperion and each ALI SCA. • During the lunar acquisition process, the S/C is maneuvered to scan an image of the moon for each SCA successively. • Since the Hyperion is not co-aligned with the ALI SCA 4, the spacecraft pointing for each month alternates between SCA4 and Hyperion.
