3. OPERATION
3-9
DISABLE SV (Disable satellite)
Every GPS satellite is broadcasting abnormal satellite number(s) in its Almanac,
which contains general orbital data about all GPS satellites. Using this
information, the GPS receiver automatically eliminates any malfunctioning
satellite from the GPS satellite schedule. However, the Almanac sometimes may
not contain this information. If you hear of an inoperative satellite you can
disable it manually. Enter satellite number in two digits and then press the [ENT]
key. To restore a satellite, enter “00”.
