GLOBAL POSITIONING SYSTEM RECEIVER
Product Description
The RFMD Global Positioning System (GPS) Receiver is
a plug-n-play module designed for OEM use. The 12-par-
allel-channel GPS receiver works in a wide variety of end
products including: marine navigation, telematics, auto-
motive navigation, and asset tracking. The GPS receiver
processes signals from all the visible GPS satellites
broadcasting RF navigation information. 鈥淎ll-in-view鈥?sat-
ellite tracking produces highly accurate, smoothed navi-
gation data. The data is relatively immune to the position
jumps that occur when fewer satellites are monitored.
Designed to withstand harsh industrial environments, the
GPS receiver performs robustly in situations where
extreme vehicle movement or high signal blockage are
concerns (such as dense urban areas).
