A222 GNSS Smart Antenna
key features
All-In-One GNSS Receiver Solution
• Atlas® L-band corrections
• Exclusive Atlas Basic option available when other differential signals are not practical
• Scalable accuracy within a single
product for different use cases
• Environment-proven enclosure for the most aggressive user scenarios
• Compact, low-profile design with fixed or magnetic mounting options make it ideal for portable and dynamic applications
The A222 GNSS Smart Antenna offers an affordable, portable solution with
professional-level accuracy for agricultural, marine, GIS, mapping, and other
Focus on the job at hand with fast start-up and reacquisition times, 60 cm
accuracy, and an easy-to-see LED status indicator for power, GNSS, and
DGNSS. The durable enclosure houses both antenna and receiver. It can be
powered through various sources, making the A222 smart antenna ideal for a
variety of applications. Dual-Serial, CAN, and pulse output options make this
DGNSS receiver compatible with almost any interface.
A222 is supported by Hemisphere’s easy-to-use Atlas Portal (www.atlasgnss.
com), which empowers you to update firmware and enable functionality,
including Atlas subscriptions for accuracies from meter to sub-decimeter levels.
