Product Information
Description
The Hemisphere GNSS A25 is a high-precision multi-constellation GNSS antenna designed to deliver millimeter-level accuracy for both land and marine applications. It supports current and future GNSS signals, including GPS, GLONASS, BeiDou, and Galileo, making it an ideal choice for surveying, single-frequency RTK positioning and navigation, precision guidance, and machine control.
The A25 delivers excellent performance in challenging environments, such as areas with nearby buildings or dense vegetation, thanks to its superior multipath mitigation, stable phase center, and high signal-to-noise ratio (SNR), even at low satellite elevation angles. Its rugged enclosure features a marine-grade aluminum base specially treated to withstand salt, fog, and water spray, while its durable construction successfully passes 2-meter pole drop testing, ensuring long-term reliability in demanding field conditions.
