Nobeltec InSight 50-W User Guide
What is WAAS?
WAAS consists of a network of ground reference stations across the United States that
monitor GPS satellite data. The master stations collect data from the reference stations
and create a GPS correction message, taking into account selective availability (SA),
GPS satellite orbit and clock drift, and signal delays caused by the atmosphere and
ionosphere. The "corrected" differential messages are then broadcast through two
Geostationary Earth Orbit (GEO) satellites on the same frequency as the GPS signal.
The result is a DGPS system that delivers superior accuracy (<3 meters).

Thank you for purchasing the Nobeltec®
InSight™ GPS 50-W.
The InSight GPS 50-W is based on a
50-channel GPS engine that delivers
location accuracy within less than 3
meters by decoding GPS correction signals
from satellite-based WAAS (Wide Area
Augmentation System).
The GPS engine, interface electronics,
and passive antenna are enclosed inside
a durable waterproof plastic housing. This
superior quality GPS provides advanced,
state-of-the-art positioning performance
and plug-and-play use with Nobeltec
Navigation Software charting programs.
Nobeltec Navigation Software (Visual
Navigation Suite™, Admiral™ or MAX Pro™
software, sold separately), interfaced
with the InSight GPS 50-W using your
onboard computer, intelligently interprets
and displays GPS data in an easy-to-
comprehend onscreen format, providing
you with the ability to make safer and more
prudent navigation decisions in shorter
periods of time.
This User Guide covers the key installation
information for the InSight GPS 50-W. It is
written for an audience assumed to have
a mid-level, pre-existing knowledge of
PC operation and the principles of marine
navigation, as well as previous marine
equipment installation experience.
This document should in no way be used
to replace actual navigation training and
experience.
