| Popis: | In the near future, the upcoming Navigation through Indian Constellation (NavIC) system will be used for navigation services in India. All services provided by the NavIC receiver must be reliable and resistant to threats. Therefore, the real-time NavIC signal is examined under intentional software defined radio based chirp-jamming by different methods. Since the NavIC signal is available for all the time, jamming scenario has been analysed through power spectral density by calculating the spectral energy distribution per unit time. Furthermore, the received signal is examined through the auto-correlation function and the signal strength monitored at receiver. The dynamic jamming scenario is used for survey and lead to the main observations. For example, the satellites IRNSS-1E, 1F and 1G are more susceptible to interference in such scenario and if the dynamic receiver is closer to interference source, the jammer becomes a serious threat which can block the NavIC signal. |
