Every GNSS satellite is broadcasting abnormal satellite number(s) in its Almanac,
which contains general orbital data about all GNSS satellites. Using this information,
the GNSS receiver automatically eliminates any malfunctioning satellite from the
GNSS satellite schedule. However, the Almanac sometimes may not contain this in-
formation. You can disable an inoperative satellite manually. Enter satellite numbers
(up to three satellites) in three digits.
