Abstract

Indian Regional Navigation Satellite System (IRNSS) is a first and independent satellite navigation system being developed by the Indian Space Research Organization. IRNSS/NavIC operates in two frequency bands, namely L5 band (1176.45 MHz) and S1 band (2492.02 MHz). Acquired NavIC signal under normal circumstances, the data is collected by assuming that there is no modification in the received code frequency due to the received Doppler frequency. The atmosphere is the medium of travelling to any signal from the satellite to the ground station. Atmosphere consists of different layers like troposphere, ionosphere, stratosphere and so on. When the signal travels in these layers, the signal is refracted and the strength of the signal changes. This paper presents a study of these effects in the IRNSS navigation signals in the Bangalore region and also presented several results dealing by means of the code Doppler effect and ionodelay on acquisition performance.
