GNSS, or Global Navigational Satellite System, is a global term that encompasses the different positioning constellations used for precision location. GPS, GLONASS, BEIDOU and Galileo are all GNSS systems. If precision location equipment is referred to as GNSS, it means the equipment is capable of using a positioning signal from more than one of the previously mentioned constellations.

Bench Mark offers the complete range of Hemisphere GNSS precision products. Hemisphere produces heading antennas, precision GNSS antennas and precision GNSS receivers for all applications. From navigation to surveying, Hemisphere has a precision GNSS product.

GPS or GNSS positioning systems are typically accurate to within a meter. Using a satellite based correction, such as WAAS (available in North America), can increase your precision to 30-50 cm. Post-Processing of your GNSS observation or a real-time kinematic system can achieve accuracy of 1-2 cm. The best accuracy achievable with a stand-alone receiver in real-time is using L-Band Corrections. Hemisphere offers a cutting-edge L-Band solution called Atlas. 10 cm accuracy is possible with Atlas L-Band corrections.

What makes Hemisphere GNSS GPS systems the best in the USA

We have what you need

Hemisphere RTK GPS and GNSS receivers in America have a variety of performance advantages over consumer-grade GPS receivers. Consumer-grade GPS receivers are used in non-precision applications such as basic navigation, asset tracking, fleet management, mobile phones, and other applications that require less accuracy. Hemisphere GPS GNSS receivers, on the other hand, are used in precision applications that require reliable positioning in the most demanding applications. For more than 20 years, Hemisphere has manufactured professional-level GPS receivers for a variety of industries including surveying, precision agriculture, marine navigation, machine control, and aerial guidance.
