Prospect for UV observations from the Moon. II. Instrumental Design of an Ultraviolet Imager LUCI
Joice Mathew, Ajin Prakash, Mayuresh Sarpotdar +6
We present a design for a near-ultraviolet (NUV) imaging instrument which may be flown on a range of available platforms, including high-altitude balloons, nanosatellites, or space…
Pointing System for the Balloon-Borne Astronomical Payloads
K. Nirmal, A. G. Sreejith, Joice Mathew +5
We describe the development and implementation of a light-weight, fully autonomous 2-axis pointing and stabilization system designed for balloon-borne astronomical payloads. The sy…
A generic FPGA-based detector readout and real-time image processing board
Mayuresh Sarpotdar, Joice Mathew, Margarita Safonova +1
For space-based astronomical observations, it is important to have a mechanism to capture the digital output from the standard detector for further on-board analysis and storage. W…
Noise modeling and analysis of an IMU-based attitude sensor: improvement of performance by filtering and sensor fusion
K. Nirmal, A. G. Sreejith, Joice Mathew +5
We describe the characterization and removal of noise present in the Inertial Measurement Unit (IMU) MPU-6050. This IMU was initially used in an attitude sensor (AS) developed in-h…
An Ultraviolet imager to study bright UV sources
Joice Mathew, Ajin Prakash, Mayuresh Sarpotdar +3
We have designed and developed a compact ultraviolet imaging payload to fly on a range of possible platforms such as high altitude balloon experiments, cubesats, space missions, et…
Balloon UV Experiments for Astronomical and Atmospheric Observations
A. G. Sreejith, Joice Mathew, Mayuresh Sarpotdar +5
The ultraviolet (UV) window has been largely unexplored through balloons for astronomy. We discuss here the development of a compact near-UV spectrograph with fiber optics input fo…
