How does the dual-mode tracking technology of Fully Automatic Sun Tracker improve the accuracy of solar radiation observation?

Fully Automatic Sun Tracker features a built-in GPS positioning module and a four-quadrant solar sensor, supporting automatic switching between light tracking and GPS tracking modes. The tracking accuracy can reach up to 0.1°, enabling accurate observation of total solar radiation, direct radiation, and diffuse radiation from any location globally. It is suitable for meteorological, photovoltaic, and agricultural and forestry research.

Fully Automatic Sun Tracker is a professional device for solar radiation observation, capable of accurately measuring total solar radiation, direct radiation, and diffuse radiation from any location globally. The device has a built-in GPS positioning module that automatically initializes and determines its location upon power-on, automatically calculates the sun's trajectory, and identifies the hemisphere, ensuring normal operation worldwide.

Regarding tracking modes, Fully Automatic Sun Tracker employs a dual-mode operation combining light tracking and GPS tracking. Under clear conditions, the device uses light tracking mode, sensing the sun's position in real time through the four-quadrant solar sensor, achieving a tracking accuracy below 0.1°. When the sky is cloudy or the sun is obscured, the system automatically switches to GPS tracking mode. Relying on built-in algorithms to calculate the sun's azimuth and altitude angles, the tracking accuracy remains within 0.5°. The two modes can switch automatically and work together, achieving all-weather automatic sun tracking.

The Fully Automatic Sun Tracker exhibits outstanding compatibility, compatible with all models of direct radiation and diffuse radiation sensors available on the market. Users can wirelessly set three operating modes—transportation, testing, and operation—via Bluetooth to suit different application scenarios. For different climate regions, the Fully Automatic Sun Tracker offers two models: a standard temperature model (operating temperature -20℃ to 55℃) suitable for southern regions, and a low-temperature model (operating stably in environments from -40℃ to 55℃) suitable for northern regions.

In terms of technical specifications, the Fully Automatic Sun Tracker is driven by a stepper motor, with a horizontal rotation angle of 0–350°, a vertical rotation angle of 0–120°, a maximum angular velocity of 4.5°/s, a payload of 17kg, a torque of 12Nm, an IP66 protection rating, and a DC12V power supply. The overall dimensions are 235mm × 181mm × 310mm, and the weight is 6kg. These parameters ensure stable operation and long-term reliability of the equipment in various outdoor environments.

The Fully Automatic Sun Tracker is widely used in many fields such as photovoltaic environmental monitoring, meteorological radiation observation, and agricultural and forestry scientific research. This equipment solves the problem of inaccurate tracking by traditional direct radiation meters, improving the measurement accuracy of direct radiation and total radiation without improving the radiation sensor, providing reliable data support for related scientific research and engineering activities.
