Khan, Durgesh Tripathi Abstract Type : Poster Abstract Category : Instrumentation and Techniques Abstract : Solar Ultraviolet Imaging Telescope (SUIT) is one of the payload on Aditya-L1. SUIT will observe the Sun between 200-400 nm wavelength range and it will provide full disk images of different layers of the solar atmosphere by making use of 11 filters. SUIT has number of operational modes, each mode comprises of different set of filter combinations in particular sequence along with fully configurable exposure parameters like exposure time, binning size and frame size. The on chip program will allow switching between several such sequences based on internal and external triggers received from other payloads. There are also specific sequences for PI driven observation modes and for calibration purpose, which shall be uploaded / selected through ground commands. Some of these sequences and parameter values may have to be defined post launch, after receiving sufficient data. Also the images along with meta-data and health and house keeping related information will be downlinked continuously through separate channels. SUIT will have all the intelligence necessary for autonomous observations (including flare detection and sun tracking), and at same time it will also listen to ground commands and execute them at right time. ISRO certified proven, heritage, space qualified FPGA has been chosen for processing and detector electronics along with the space grade SDRAM and EPROM. Compare to the current generation of FPGAs that are available in the market, this one has limited resources and lack in feature like DSP. In this poster, we present the instruction set based design and architecture of the SUIT processing electronics and describe how in spite of various constraints, it achieves all above mentioned goals. It not only meets the current science objectives but also has provision to handle any post launch unforeseen situation(s). |
