Abstract： With the growing significance of space weather forecasting, multi-layer magnetic and helioseismic telescopes are emerging as a key area of research. However, owing to the diverse operational processes and sophisticated hardware configurations of these devices, there is an urgent need for efficient autonomous observation capabilities. An autonomous Master Control System (MCS) can ensure efficient performance, data consistency, and stability, and the prototype presented here adopts a microservices architecture, breaking down the hardware into multiple subsystems and converting their functions into individual services. A central decision-making system leads the operations, supported by three auxiliary systems and three device control systems. Through inter-subsystem service calls, it achieves rapid imaging and spectroscopic monitoring. To verify system stability and observation efficiency, the system was tested on the Solar Full-disk Multi-layer Magnetograph. Experimental results verify this system can operate automatically for 4 consecutive months, acquire photospheric vector magnetic and Doppler velocity fields within a 15-minute interval, and measure chromospheric longitudinal magnetic and Doppler velocity fields in under 180 s. This ensures consistent and stable solar monitoring and serves as a practical methodological benchmark for the development of similar devices.

Abstract： The Solar Upper Transition Region Imager (SUTRI) onboard the Space Advanced Technology demonstration satellite (SATech-01), which was launched to a sun-synchronous orbit at a height of 500 km in July 2022, aims to test the on-orbit performance of our newly developed Sc-Si multi-layer reflecting mirror and the 2kx2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of 3 nm. SUTRI employs a Ritchey-Chretien optical system with an aperture of 18 cm. The on-orbit observations show that SUTRI images have a field of view of 41.6'x41.6' and a moderate spatial resolution of 8" without an image stabilization system. The normal cadence of SUTRI images is 30 s and the solar observation time is about 16 hours each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period. Approximately 15 GB data is acquired each day and made available online after processing. SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of 0.5 MK in the solar atmosphere, which has rarely been sampled by existing solar imagers. SUTRI observations will establish connections between structures in the lower solar atmosphere and corona, and advance our understanding of various types of solar activity such as flares, filament eruptions, coronal jets and coronal mass ejections.
