Geode GNS3 Real-Time Sub-Meter GPS Receiver
1. Introduction
The Juniper Systems Geode GNS3 GNSS Receiver is a sub-
meter, sub-foot, and decimeter capable GNSS receiver. With
the Geode, you can collect real-time, sub-meter, sub-foot,
or decimeter GNSS data. It works with a wide range of
iPhone®, iPad®, Android®, and Windows® devices to fit
your needs. Take the Geode with you mounted on a pole, in
a pack, or held in your hand to collect real-time GNSS data
in harsh environments—including heavy tree canopy and
mountainous areas—using almost any handheld device.
Like other Juniper Systems
products, the Geode is
built ultra-rugged. Rated
IP68, it is dustproof as well
as waterproof to a depth
of 1.4 meters (4.5 ft) for 30
minutes or longer. It can
survive multiple drops from
1.2 meters (4 ft) to concrete.
It is designed to withstand
harsh environments and
provide a consistently
reliable performance.
While stand-alone single-
frequency GPS receivers
are accurate to only two to
five meters or more, the
Geode uses NTRIP, SBAS,
or Atlas™ corrections
and combines complex
smoothing algorithms and full-wave carrier phase tracking
to deliver sub-meter, sub-foot, or decimeter accuracy
depending on the configuration.
Note: GNSS accuracy is subject to observation conditions,
multipath environment, number of satellites in view,
satellite geometry, and ionospheric activity.
The Geode GNS3 is available in two hardware configurations
with multiple activations and subscriptions to meet a
variety of needs.
