The Guidance Control Section adopts GPS/BD geomagnetic and single-channel control technology to measure the rocket's flight trajectory. When the real-time flight path deviates from the theoretical trajectory, it continuously sends commands to the actuator to adjust the flight attitude by altering aerodynamic movement. This process controls the flight trajectory and corrects the predicted impact point, and it continues until the rocket reaches the target area.
GCS can be mounted on unguided rockets via the original fuze interface. Parameters can be configured via wireless transmission. It supports both proximity and impact detonation. By adding guidance correction capability, it significantly improves the hit accuracy of unguided rockets.

The GCS mainly consists of a wireless configuration module, fin control system, GPS/BD antenna, thermal battery, integrated controller, and safety & arming mechanism. Its composition is shown in the following figure:
To minimize equipment modifications, upgrading an unguided rocket is possible simply by connecting the GCS to the original fuze interface. The corresponding diagram is presented below.
The main additional step introduced in rocket operation is the extraction of GNSS data.* *Note: If GNSS data extraction is successfully completed, the GNSS information can be loaded into the GCS via a handheld configuration device, which shortens the GCS initialization time. Otherwise, the startup time will increase, and hit accuracy cannot be guaranteed. Based on current meteorological conditions, parameter calculations are performed—including basic trajectory data, control parameters, etc. These parameters are then configured wirelessly.
