    Mathew, J; Nair, B. G; Safonova, M; Sriram, S; Prakash, A; Mayuresh, Sarpotdar; Ambily, S; Nirmal, K; Sreejith, A. G; Murthy, J; Kamath, P. U; Kathiravan, S; Prasad, B. R; Brosch, Noah; Kappelmann, Norbert; Gadde, Nirmal Suraj; Narayan, Rahul (Springer, 2019-03)
    The Lunar Ultraviolet Cosmic Imager (LUCI) is a near-ultraviolet (NUV) telescope with all-spherical mirrors, designed and built to fly as a scientific payload on a lunar mission with Team Indus—the original Indian entry to ...
  • A Raspberry Pi-based attitude sensor 
    Sreejith, A. G; Mathew, J; Mayuresh, Sarpotdar; Mohan, Rekhesh; Akshata Nayak; Safonova, M; Murthy, J (World Scientific Publishing Co., 2014-11)
    We have developed a lightweight low-cost attitude sensor, based on a Raspberry Pi, built with readily available commercial components. It can be used in experiments where weight and power are constrained, such as in ...
  • A software package for evaluating the performance of a star sensor operation 
    Mayuresh, Sarpotdar; Mathew, J; Sreejith, A. G; Nirmal, K; Ambily, S; Prakash, A; Safonova, M; Murthy, J (Springer, 2017-02)
    We have developed a low-cost off-the-shelf component star sensor (StarSense) for use in minisatellites and CubeSats to determine the attitude of a satellite in orbit. StarSense is an imaging camera with a limiting magnitude ...
