ABSTRACT
Radio astronomy has a wide electromagnetic spectrum. It is based on antennas, electronics, and software. The radio data obtained from distant objects like stars, galaxies, pulsars are useful for studying the Universe. Many of the radio emissions, especially from the Sun have been studies over decades for understanding the ionosphere and its effects on radio communication.
In this study, we will build and operate an affordable, low frequency radio telescope, consisting mainly of a Satellite Antenna dish of 68cm parabolic dish reflector and a Low Noise Block (LNB) which is the radio receiver. The LNB receives the radio signal from the satellites reflected by the dish and amplifies it. The Arduino Uno is a microcontroller board. Finally we will configure the radio skypipe to receive digital signals from the Arduino microcontroller. The telescope is used to analyze signals from the satellite belts. With the set-up one will be able to measure the brightness, temperature and flux of the Satellites and calculate the beam width of the antenna.
The low cost radio telescope will be calibrated with the geostationary Satellites and power per unit voltage was calculated. Then for the temperature calculation, power density will be calculated given aperture efficiency followed by the flux calculation.
