A101 Smart Antenna

The A101 GNSS Smart Antenna from Hemisphere GNSS has reached End of Life (EOL). Hemisphere GNSS recommends the A222 GNSS Smart Antenna as a suitable replacement.



The Hemisphere GPS A101 Smart Antenna is an antenna and a receiver housed in a rugged enclosure. It is capable of tracking GPS L1 signals and is well suited for a wide range of applications, including applications used in marine, agricultural and GIS mapping.

The A101 offers fast start-up and reacquisition times, as well as accuracy of up to 60 cm. Furthermore, its has a high output rate of up to 20 times per second, making it ideal for applications that require reliable steering signals and visual guidance.

Hemisphere GPS COAST technology allows the A101 smart antenna to make sure of previous differential correction data at times of signal interference or blockage. With the COAST technology, it is capable of maintaining sub-meter positioning for 40 minutes, even when no differential signals are available.
