Implementation of a signal generator to countermeasure the navigation signal interference

This paper presents the implementation scheme and test result of GNSS signal generator on the hardware platform to countermeasure the GNSS signal interference. The signal generator can be helpful for mitigating the GNSS signal interference. It can be proven firstly the function of GPS signal then prove the function by using hardware platform level. To generate the GNSS signal, Doppler frequency, code and carrier phase can be getting from RINEX(Receiver Independent Exchange Format) data which is saved in previously other material. If GPS interference signal can be happened at particular Pseudo Random Number(PRN) of satellites, it can generate the corresponding GPS signal by using signal generator which is implemented on the Hardware platform. This paper presents the conceptual design result and preliminary functional test of GNSS signal generator by using software receiver to test the function of navigation solution.
