“…The satellite and SEC CPU software (SECCS, The version number is 2.05) data flow of the turntable control is illustrated in Figure 2b. The SECCS receives the satellite attitude in a broadcast message and the solar vector in an orbit message sent by satellite through the 1553B (Military Standard 1553 bus, a standard for communications that was developed by the United States Department of Defense) [31][32][33][34]. Using these data and the mechanical installation matrix, the azimuth and pitch angles of the sunlight at the GMCS are calculated by the SECCS immediately.…”

At present, solar remote sensing instruments face problems regarding the short detection time for solar activity and the need to preheat the electronics before detection. The accurate orbit prediction function ensures that the maximum error of the payload electronics system preheating time is less than 8 s, enabling the electronics to obtain stable and reliable solar remote sensing data, and allowing the prediction function to adapt to the changes in preheating time and the limit position of turntable rotation. To achieve the complete detection of solar activity by a payload in orbit, a turntable with two directions of rotation was accurately controlled to achieve rapid capture and track the Sun’s activity, and the delay time for tracking the Sun successfully was less than 8 s to ensure that the payload made full use of the solar detection time for full detection. The turntable’s tracking error was less than 0.002°, allowing the payload to obtain high-precision solar remote sensing data in orbit. The above methods enable the payload to realize the complete, stable, and high-precision detection of solar activity in orbit for wavelengths ranging approximately from 165 nm to 2400 nm.
