Signal reections are another important error source
for base stations that should be minimized. Reected
signals also reach the base station receiver and make
the satellite range measurement longer. Reections can
even interfere with the direct signal enough so that the
receiver will temporarily lose lock on the satellite. Metal
buildings, chain-link fences, and bodies of water are all
good reectors that can make a base station less reliable.
Take care to place your base station receiver far away
from strong reectors for reliable base station operation.
A base station should have a continuous 12V power
source such as an AC/DC converter to power the base
station. A battery back-up is recommended to keep the
base station running in the case of power outages for
dependable operation.
NOTE: The AC/DC converter is not supplied
by John Deere.
