CHCNAV AT315 GNSS Antenna – Reliable GNSS Signal Reception for Machine Control

The CHCNAV AT315 is a GNSS antenna designed for the MCNAV machine control system, tasked with receiving precise satellite positioning data for determining machine location. The AT315 works in conjunction with the CHCNAV MC300 GNSS receiver, forming a critical component of the 3D machine control positioning solution.

Reliable GNSS signal reception is essential for accurate machine control. The AT315 provides the MC300 receiver with a high-quality satellite signal, which is utilized in determining the position of the machine and its implements.

Precise GNSS signal reception

The AT315 is specifically designed for the needs of the MCNAV machine control system. The antenna receives GNSS satellite signals, which the MC300 receiver processes into precise positioning data.

When GNSS positioning is combined with the attitude data from the IS300 IMU sensor and the machine's geometric data, the MCNAV system can determine the precise location of the implement in real-time.

Part of a precise positioning chain

The AT315 operates in conjunction with the MC300 GNSS receiver. The antenna receives GNSS signals transmitted by satellites and relays them to the receiver for positioning calculations.

In the MCNAV system, GNSS positioning, together with the IS300 IMU sensor, forms the basis for determining the precise position of the machine and its implement.

This allows the operator to monitor, for example, the position of the bucket relative to the design model and control work with greater precision.

Designed for 3D machine control

The AT315 is part of the CHCNAV TX73 3D machine control solution. In this system, the AT315 GNSS antenna, MC300 receiver, and IS300 IMU sensor form an integrated unit that allows the machine's position and attitude to be determined in real-time.

The solution is particularly suitable for excavators, where precise implement positioning is an important part of efficient and high-quality work.

Durable construction for job site use

The AT315 is designed for the demanding operating conditions of earthmoving machinery. The antenna's IP68 protection helps shield it from dust and water, and the device is designed to operate over a wide temperature range. According to CHCNAV TX73 documentation, the AT315's operating temperature range is -40 °C to +75 °C.

The antenna is compact and suitable for machine installation, allowing it to be integrated as part of the overall machine control system.
