Ready for Galileo (Factory optional)

• A20 also support Galileo and Compass satellites When Galileo and Compass are ready, FOIF will be too.

Voice messages

• A20 receiver of its kind to provide audible status notification in the field.

Super bright OLED display & LED

• OLED has many superior performance advantages over LCD: Super-bright, wide viewing angle, quick response time, energy efficient, operational under -40 to 80 and rugged environment.
• Provides status indicators for satellite tracking, battery life, remaining memory, occupation time and communications.

Ergonomics

• A20 has a comprehensive built-in interface for receiver monitoring. This interface is based on a OLED graphical display and functional keys that enable the user to interact directly with the GNSS receiver. You can set or check GNSS receiver status easily, such as language, volume, GPRS, radio, or elevation mask, etc.

Convenient rover setup

• Quick and easy setup requires only a pole, data collector with bracket and the A20 receiver no cables necessary, easy-to-use.
• Interoperability with main vendor's reference station using UHF.

Easy "one Button" base setup

• Press the power button, and begin transmitting RTK base corrections and collecting raw data in seconds.
• No cables, external data link or data collector required.

Seamless Virtual Reference Station support

• Compatible with Virtual Reference Station, FKP and Master Auxiliary reference networks Supports GSM dial-up connections and NTRIP GPRS connections, also support CDMA.
• Allows stand-alone RTK rover positioning - no base required.

All-in-one Flexibility

• A20 series offers all-in-one communication capabilities. It is the most flexible GNSS surveying system available, offering multiple operating modes, configurations and communication modules(internal& external UHF,GSM/GPRS/EDGE/CDMA) and protocols.
• Features such as OLED display with backlit LED lights, SD-card, high capacity Li-ION battery and Bluetooth wireless technology. USB and Ethernet also could be supported (Factory optional). External power supply 6~18V DC are available.
• Battery can be charged onboard.
