Small and lightweight, the Geode is easy to pack around all day.
All-In-One Design
The inside of the Geode contains the receiver, antenna, and battery, making it easy to carry around and mount without a mess of wires.
Juniper Rugged™
Designed to withstand harsh environments for consistently reliable performance.
Galileo High Accuracy Service (HAS)
The new GNS3H model of the Geode family adds support for the Galileo High Accuracy Service (HAS) to provide free, worldwide 20cm accurate positioning. The Galileo HAS is currently in Initial Phase, meaning that the performance and time standards are currently relaxed so that the EUSPA (European Union Agency for Space Programme) can complete their design and testing to complete the Final Phase of operations with better than 20cm performance in under 5 minutes convergence time (see excluded areas in map below). Simply apply a multi-frequency upgrade to any GNS3H receiver and you have instant access to 20cm real-time location accuracy without any additional subscriptions, downloads or software. The Galileo High Accuracy Service provides precise corrections in the Galileo E6B data signal so that Galileo and GPS signals can achieve real time positioning performance of better than 20cm in nominal conditions. With Galileo HAS, Sub-meter becomes Sub-foot as the new standard for free and open global GNSS positioning.

Monitoring Meadowbrook Creek: Real-Time Data Collection in an Urban Creek
Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. 
 
 Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing.

Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing.

 Telling Lancaster County's Story Through Data 
Since the Lancaster County Conservation District started monitoring county waterways, the goal has remained the same, according to Amanda Goldsmith, Watershed Specialist for the Watershed Department.

In the early 2000s, along the coast of northern California, where the redwoods dominate the forests, and the Pacific Ocean shapes shorelines, a Humboldt University undergraduate student took the first steps into a lifelong love of marine biology. 
 
Dean Janiak accepted an invitation to help a graduate student with fieldwork in rocky coastal tide pools, and so began a journey that led him from California to Connecticut to Florida and eventually to the world, where he has facilitated research in communities across the globe. 
 
While finishing up his masters of Oceanography from the University of Connecticut, Janiak continued researching fouling communities–marine life that live on hard, often artificial surfaces such as docks–at the Smithsonian Environmental Research Center.
