Subject: Single Chord Operations - Issued 10/14/99
GOES "single chord" operations, made necessary by lunar and solar
intrusions at the edge of the Earth disk, impact navigation and
registration for short periods. Users of GOES GVAR data will
see variable errors during periods of single chord operations as
noted below.
Single Chord Operations for the Bevel effect are listed when
applicable. Bevel effect operation is intended to avoid a
seasonal spacecraft pointing problem with all GOES spacecraft
caused by the sun's light reflecting into the earth sensor.
Following are times of GOES-8 single chord operations for the
period October 11, 1999 to November 09, 1999.
