Why the SIM66D GNSS Module with RTK is Essential for Precision Applications
In industries such as agriculture, surveying, and autonomous systems, the demand for highly accurate positioning solutions is growing rapidly. Traditional GNSS modules, while effective for basic navigation, often fall short when precise, real-time positioning is required. This is particularly true in environments where accuracy down to the centimetre is critical, such as in precision farming or robotic navigation.
Enter Real-Time Kinematics (RTK) technology, which enhances GNSS accuracy by leveraging data from reference stations to correct positioning errors in real time. With many legacy GNSS modules unable to meet these demands, the need for advanced, efficient modules like the SIM66D has become clear. The SIM66D offers RTK support, multi-constellation tracking, and low power consumption, making it an ideal solution for modern applications requiring high-precision GNSS positioning.
