TRANSFORMING THE WAY THE WORLD WORKS
TECHNICAL PUBLICATION
Superior performance under
challenging GNSS environments,
with groundbreaking measurement
management that leverages the latest
developments in GNSS and Inertial
sensor fusion.
INTRODUCTION
In 1992, Trimble® released the world's first
commercial GPS (Global Positioning System)
receiver capable of performing centimeter
accurate Real Time Kinematic (RTK)
positioning. Although this first generation
system required the user to position the rover
over a known location to initialize the system,
it was revolutionary for land surveyors
enabling topographic mapping, stakeout and
Trimble ProPoint Engine - Next Generation
Centimeter Positioning and Orientation
as-built surveys in real-time.
Follow-on applications such as construction
machine control and agriculture resulted in
positioning engines that have delivered rapid
on-the-fly initializations and high update
rate, low latency positions. This technical
bulletin provides an overview of the Trimble
ProPointâ„¢ Engine, the fifth generation RTK/
RTX precision positioning engine, engineered
to provide positions and orientation from the
fusion of GNSS signals, worldwide correction
services and measurement data from a
variety of sensors.
