CHCNAV MC300 GNSS Receiver – Precise Positioning for Machine Control

The CHCNAV MC300 is a high-performance GNSS receiver designed for machine control systems, providing accurate and reliable positioning data for 3D machine control of earthmoving equipment. The MC300 operates as part of the CHCNAV MCNAV system, combining precise GNSS positioning with the attitude information of the machine and its implement configuration.

The MC300 enables precise real-time determination of the machine's location and helps the machine control system calculate the tool's position relative to the design model.

Precise GNSS Positioning for Machine Control

The MC300's function is to provide accurate real-time positioning data to the machine control system. RTK technology allows for centimeter-level positioning, which is crucial in precise earthmoving.

In the MCNAV system, the MC300 works in conjunction with the IS300 IMU sensor and a GNSS antenna. With this information, the system can determine the position of the machine and the tool even when the machine is in motion.

Key Benefits

• Accurate GNSS receiver for machine control
• RTK positioning with centimeter-level accuracy
• Real-time positioning data updates
• Designed for the CHCNAV MCNAV machine control system
• Compatible with the IS300 IMU sensor
• Enables precise determination of bucket and tool position
• Suitable for demanding earthmoving applications
• Industrial-grade construction and reliable operation
• IP67 protection rating
• Compact design suitable for machine installation

Precise RTK Positioning

The MC300 utilizes RTK positioning to determine the precise location of the machine. According to the technical specifications of the CHCNAV MCNAV TX73 system, RTK positioning accuracy is 8 mm + 1 ppm RMS horizontally and 15 mm + 1 ppm RMS vertically.

Precise positioning data forms the basis for 3D machine control. When GNSS location is combined with the machine's geometric data and the attitude information from the IS300 IMU sensor, the system can determine, for example, the position of an excavator's bucket relative to the design model.

Part of the MCNAV 3D Machine Control System

The MC300 is designed as part of the CHCNAV MCNAV machine control solution. In the complete system, the receiver works in conjunction with the MCPad300 display, AT315 GNSS antenna, and IS300 IMU sensor.

The cooperation of these components enables real-time monitoring of the machine's position and attitude, as well as precise calculation of the tool's location.

Accuracy for Excavation Work

Thanks to precise GNSS positioning, the MC300 helps the operator work according to the digital design model. The machine control system can show the operator where the bucket is located in relation to the target elevation, designed surface, or slope.

This facilitates, for example, the control of excavation depth and precise finish grading, and reduces the need for continuous separate measurement.

Designed for Demanding Construction Site Use

The MC300 is designed for the demands of machine control and continuous construction site use. The receiver's IP67 protection rating helps protect the device from dust and water in construction site conditions. The receiver's dimensions are 215 × 154 × 58 mm and its weight is 1.11 kg.

CHCNAV states that the MC300 is an industrial-grade receiver designed to withstand the demanding use of machine control.

Suitable for Versatile Machine Control

The MC300 is suitable for, for example:

• 3D machine control for excavators
• GNSS-based machine positioning
• excavation depth control
• foundation excavation
• construction of slopes and grades
