Signal reflections are another important error source
for base stations that should be minimized. Reflected
signals also reach the base station receiver and make
the satellite range measurement longer. Reflections 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 reflectors that can make a base station less reliable.
Take care to place your base station receiver far away
from strong reflectors 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.
