  • 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 ...
  • Spectroscopic Investigation of Nebular Gas (SING): a dedicated NUV spectrograph to study extended objects 
    Bharat Chandra; Nair, B. G; Suresh, Ambily; Prabha, C. S; Mathew, J; Nirmal, K; Sarpotdar, Mayuresh; Mohan, R; Safonova, M; Sriram, S; Murthy, J (SPIE--The International Society for Optical Engineering, 2019-01)
    SING is a near ultraviolet (NUV) spectrograph with a size close to 6U CubeSat form-factor. The spectrograph operates in the wavelength range from 1800 Å to 3000 Å, with a spectral resolution of 2 Å at the central wavelength. ...
  • An ultraviolet imager to study bright UV sources 
    Mathew, J; Prakash, A; Mayuresh, Sarpotdar; Sreejith, A. G; Safonova, M; Murthy, J (SPIE-The International Society for Optical Engineering, 2016-07)
    We have designed and developed a compact ultraviolet imaging payload to y on a range of possible platforms such as high altitude balloon experiments, cubesats, space missions, etc. The primary science goals are to study ...
  • Wavelength calibration of a tunable spatial heterodyne spectrometer 
    Nirmal, K; Sridharan, R; Sriram, S; Ambily, S; Mathew, J; Mayuresh, Sarpotdar; Murthy, J; Binukumar, G; Safonova, M (SPIE-The International Society for Optical Engineering, 2018-07-06)
    Spatial Heterodyne Spectroscopy (SHS) is a relatively novel interferometric technique similar to Fourier transform spectroscopy and shares design similarities with a Michelson Interferometer. An Imaging detector is used ...
  • Wide-field ultraviolet imager for astronomical transient studies 
    Mathew, J; Ambily, S; Prakash, A; Mayuresh, Sarpotdar; Nirmal, K; Sreejith, A. G; Safonova, M; Murthy, J; Brosch, N (Springer, 2018-04)
    Though the ultraviolet (UV) domain plays a vital role in the studies of astronomical transient events, the UV time-domain sky remains largely unexplored. We have designed a wide-field UV imager that can be flown on a range ...
