• Supports SBAS, QZSS, QLL

Triple Wireless Technologies Inside

Three commonly-used wireless technologies can be integrated into the GRX2 receiver.

• Digital UHF Modem (receiver/transmitter): for RTK base and rover
• GSM/HSPA Modem: for network RTK, and MAGNET Relay
• Bluetooth® Modem: for controller and other PC

Maximum Versatility in RTK Applications

Utilizing full wireless connectivity and voice navigation system, the GRX2 facilitates the use of both RTK and network RTK technologies.

• Built-in GSM/HSPA modem makes the GRX2 an ideal  rover receiver for network RTK positioning.
• Can be used for both private RTK base and RTK rover using an internal digital UHF modem without any extra device.
• MAGNET Relay Ready - Cellular to Cellular base/rover RTK.
• Voice messages notify the users when RTK is fixed or lost, or other  problems occur.

Other Hardware Features

• 22 status LED displays are exceptionally viewable even under bright sunlight.
• Data storage in popular SD/SDHC cards.
• IP67 dust/water protection.
• One detachable battery powers the receiver for up to 6 hours in RTK usage  with UHF radio communication.
