This description is focussed on the GPS receiver of the FALCOM
JP2 series from FALCOM GmbH. It contains some short information
about purpose and use of the GPS receiver. The GPS receiver is a
single-board 12 parallel channel receiver intended as a component
for OEM Products. The GPS receiver continuously tracks all satelli-
tes in view, thus providing accurate satellite position data. The highly
in-tegrated digital GPS receiver uses the Zodiac 2000 chip set com-
po-sed of two custom CONEXANT devices together with suitable
memory devices.
Please consult CONEXANT for special information about the GPS
Zodiac 2000 chip set.
