GPS 24xd HVS
The highly accurate GPS 24xd HVS position receiver/antenna provides up to 10 Hz update rates for position, velocity and time data. It offers high-sensitivity reception and enhanced position acquisition to the Garmin family of marine instruments, autopilots and multifunction displays.
Delivers Precise Location Data
This receiver is capable of tracking multiple global navigation satellite systems, including GPS, Galileo, GLONASS and BeiDou. Since more satellites are visible, it can provide more accurate fixes in challenging conditions. WAAS-capable, it can determine precise location to within <1 meter CEP, <3 meters 95%.
Observable Advantages
Compared to units with slower update rates, the GPS 24xd offers dramatic improvement when used at low speeds. Position and course information from slower units can jitter and swing considerably at speeds below 1 mph. The GPS 24xd provides a consistent and smooth heading which is especially important when trying to hit a specific waypoint or mark.
Built for Versatility
Part of the Garmin marine instrument family, the GPS 24xd HVS is built to withstand the elements. This waterproof (IPX7) sensor can be pole mounted or flush mounted. It also can be attached to the underside of many fiberglass decks for added ease of installation. In addition, it also can be configured to have 1 Hz or 5 Hz update rates to help support specific installation requirements.

Three Decades of Research at Acton Lake
A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.

Source Water Monitoring in Albany, New York: Tracing Water Quality throughout Tributaries
Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute
Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.
