Under the same conditions, ETALK protocol can significantly reduce the bit error rate of weak signals and the communication distance can be increased by 20 percent.

The compact, rugged eRadio is particularly well suited for heavy-duty outdoor use. It is designed for easy mobile use with an organic light-emitting diode display screen for demanding field conditions. The IP67 full metal cover provides dust and water resistance that keeps surveyors working with confidence and efficiency.

Real-time kinematic (RTK) integration usually uses separate antennas, which can lead to reduced efficiency because of electro-magnetic interference (EMI).

Also, conventional antenna installation can result in unstable machine performance because of the problems of system compatibility between different antennas.

Harxon has overcome those difficulties with its integrated X-Survey antenna, a 4-in-1 OEM antenna for both navigation and communication in surveying applications.

It provides standard Wi-Fi, Bluetooth and 4G, plus multiple constellation signal reception for GNSS positioning.

The high-gain and wide-beamwidth GNSS antenna features a multi-point feeding technology, ensuring a high phase-center stability and positioning accuracy. Moreover, the array-arranged 4G antennas enables more stable signals and longer communication distance at 360-degree direction, increasing the overall machine efficiency over conventional antennas.

The X-Survey antenna provides high isolation among each antenna to prevent self-interference, improving RTK system compatibility. RF coaxial connectors are designed for plug-and-use, keeping high efficiency and lowering the impact of EMI.

The antenna low-noise amplifier (LNA) features excellent out-of-band rejection performance, which can also suppress the EMI, providing reliable GNSS signals.

The unique structure design simplifies RTK integration, and minimizes the overall machine dimension. Harxon aims to bring system integrators high-efficiency performance of navigation and communication in surveying and precision agriculture applications.
