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®...

Owner's Manual 1.1 Geode, Geode GNS2, and Geode GNS3 Features that are specific to the Geode GNS3 are identified throughout this manual. For information about the Geode and Geode GNS2, see the Geode Owner’s Manual. Juniper Systems offers two GNS3 models, the GNS3M and the GNS3S.

Page 12: Geode Features
Geode GNS3 Real-Time Sub-Meter GPS Receiver 2. Geode Features The Geode is a real-time, sub-meter, sub-foot, or decimeter receiver. This means the Geode is able to deliver sub- meter, sub-foot, or decimeter accuracy, depending on the configuration, with 95–98% precision in the very moment the data is being collected.
Page 13: Gps Vs. Gnss
Owner's Manual For the Geode in ideal conditions, 95–98% of the points on a scatter plot will fall within a sub-meter radius of the true point. GPS manufacturers quote their accuracies in different ways. They use different statistical descriptions of probability. A GPS receiver may be sub-meter.
Page 14 Geode GNS3 Real-Time Sub-Meter GPS Receiver The Global Positioning System (GPS) is the United States government’s navigation satellite constellation. As of June 2021, the GPS constellation consists of 31 operational satellites. You can view six or more GPS satellites from virtually any point on the planet.
Page 15: Gnss Augmentation
Owner's Manual a fix on multiple satellites simultaneously, even under thick canopy or in the middle of a densely populated city block. With more satellites available to the Geode, total data sets in challenging environments are consistently higher quality. The Multi-GNSS configuration of the GNS3 makes the Geode’s ability to deliver real-time...
Page 16: Sbas Differential Correction
Geode GNS3 Real-Time Sub-Meter GPS Receiver They include flat, open landscapes with clear skies and no buildings or trees interfering with the receiver’s direct line- of-sight to at least four, perfectly positioned satellites. But even these ideal conditions require corrections because the ionosphere is constantly changing and users have no control over satellite orbits or timing.
Page 17: Ntrip Differential Correction
Owner's Manual SBAS corrections—called deviation corrections—allow GPS receivers to more accurately and reliably determine their position. GPS is normally accurate to about five meters, but when using SBAS user’s can achieve an accuracy of two meters or better. The Geode combines SBAS corrections with complex smoothing algorithms and full-wave carrier phase tracking to deliver accuracies better than 60 cm 2DRMS.
Page 18 Geode GNS3 Real-Time Sub-Meter GPS Receiver communications. Just like GNSS satellites, RTK radio signals must be sent and received via direct line-of-sight. This limits the area around which a base station can be useful. NTRIP changes this by allowing the base to send its positioning and corrections data via the internet, widening the range of application for each base station.
Page 19: Atlas Correction Service
Owner's Manual 2.3.3 Atlas Correction Service The Atlas Correction Service is a worldwide L-band satellite based correction that covers 75° north and south of the equator. The Geode GNS3M includes an option to subscribe monthly or annually to Atlas to receive extra corrections. The three options provided are Atlas Basic, H30, and H10.

Page 123: Home Page
Owner's Manual 9.1 Home Page The Home page for Geode Connect serves as a dashboard for the Geode receiver. On this page, you can view connection status, correction mode, and positioning data. It displays latitude, longitude, altitude, estimated horizontal error, fix info (GPS, DGPS, RTK, etc.), speed, heading, number of satellites in fix, PDOP, and correction signal.
Page 124: Skyplot Page
Geode GNS3 Real-Time Sub-Meter GPS Receiver 9.2 Skyplot Page The Skyplot page shows which satellites are being used in the positioning solution and where they are in the sky. It also shows satellites that are being tracked by the Geode.
Page 125 Owner's Manual Satellite symbols outlined in red indicate that the satellites are being tracked, but they are not yet a part of the positioning solution. Satellite symbols outlined in blue indicate that a correction is being applied to the signal. The Skyplot page is meant to be used as a guide.

Page 139 Owner's Manual Correction Source This specifies whether the Geode should automatically choose its correction source or accept only SBAS, NTRIP, or Atlas corrections. When the correction source is set to Auto, the Geode is programmed to choose a source according to accuracy level in the order of NTRIP, Atlas, then SBAS.
Page 140 Geode GNS3 Real-Time Sub-Meter GPS Receiver SBAS This specifies which SBAS satellites the Geode should use for GPS correction. Usually, selecting Auto is sufficient, since the various SBAS services cover very different geographical areas. However, there are some areas where these services overlap (see map below).
Page 141 Owner's Manual In areas of overlap, the best practice is to select a specific SBAS service from which the Geode should accept corrections data. ■ Auto: Sets the appropriate SBAS PRNs based on the autonomous GPS position. ■ EGNOS: European Geostationary Navigation Overlay Service (Europe SBAS) PRN 120, 124, 126 ■...
