The World’s Most Advanced GNSS Receiver for Every Mobile Device
The Eos Arrow Gold is a high-accuracy Bluetooth GNSS receiver that implements all four global GNSS constellations (GPS, GLONASS, Galileo, BeiDou), multi-frequency, and satellite-based RTK augmentation on iOS, Android, and Windows. Moreover, the new Arrow Gold+ adds full-band support for all GNSS signals, including Galileo’s free High-Accuracy Service (HAS). Both the Arrow Gold® and Arrow Gold+™ receivers support connection to popular apps like Esri’s ArcGIS apps and other mobile GIS apps on iOS, Android, and Windows.
RTK in Poor Cell Coverage Areas
SafeRTK is the answer. SafeRTK is a proprietary feature included exclusively with the Arrow Gold and Arrow Gold+ receivers. When cellular connection to the RTK network drops, SafeRTK takes over within a few seconds and maintains RTK-level accuracy for up to 20 minutes. This enables uninterrupted RTK accuracy in spotty areas.
No RTK Network?
The Arrow Gold supports low-cost global corrections. The Eos Arrow Gold features a 4cm, real-time satellite correction service called Atlas, available globally. Using all four constellations and signals, the Arrow Gold offers convergence times as low as 15 minutes at a revolutionary price point.
Multiplexing with the Arrow Gold+
The Arrow Gold+ has the functionality of the Eos Bridge Bluetooth connector built-in. Connect the Arrow Gold+ to any third-party sensor (e.g., laser rangefinder). The Arrow Gold+ will stream the content of that sensor to a chosen iOS or other mobile devices via the receiver’s own location datastream.
Ultimate Flexibility in Mobile Accuracy
iOS, Android, and Windows compatibility is our expertise. Eos Positioning Systems offers GNSS hardware with some of the most innovative, advanced connectivity on the market, supporting connection to popular apps like Esri’s ArcGIS and other mobile GIS apps.

Lake Erie Volunteer Science Network: Building Trust in Citizen Science Programs
Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. 
 
[caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. 
 
Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit.

Lightweight and easy to use, the SonTek CastAway offers a convenient 3-in-1 solution for measuring conductivity, temperature, and depth profiles. At a 5 Hz sampling rate, the CastAway is designed for up to 1 m/s free-fall through the water column. 
 
 With fast response and accurate conductivity, temperature, and depth measurements, the CastAway is ideal for thermocline and halocline profiling. The unit also reports salinity and speed of sound.
