Chapter 1 - Introduction
OVERVIEW
Nearly a decade of Global Positioning System (GPS) experience, combined with world-class
expertise in semiconductor products and communications development, has led Motorola to the
production of the M12+ GPS receiver modules, more compact and lightweight than ever before.
Each channel independently tracks both code and carrier for the superior performance required in
today's GPS user environment. Specifically designed for embedded applications, the M12+, when
combined with our range of active micro-strip patch antennas, affords the engineer new freedom
in bringing GPS technology to the most demanding Original Equipment Manufacturer (OEM)
applications. M12+ receiver offerings include:
M12+ Positioning Receiver
The M12+ Oncore positioning receiver is a12-channel design offering one of the fastest Time to
First Fix (TTFF) specifications in the industry, and split second reacquisition times.
M12+ Timing Receiver
The M12+ timing receiver is a variant of the M12+ positioning receiver, and its highly optimized
firmware makes it one of the most capable timing receivers on the market. Standard features
include precise, programmable, one-pulse-per-second (1PPS) or 100 pulse-per-second (100PPS)
outputs and features Motorola's T-RAIM integrity monitoring algorithm.
