Beidou system interference signal check
BeiDou Navigation Satellite System is developed rapidly these years, however it still faces some problems now. One of the problem is signal interference, just like the similar like the GPS. One of GNSS station of BeiDou System found that their signal will be interfered at certain time everyday, so they invited Transcom Instruments to do Trouble Shooting for them. Trasncom Instruments set a simple test in the field, SpecMini was used as Spectrum Analyzer to do the interference location, A6 was used for recording IQ data, which will be used for further analytic. After sampling and inteference location, the interference source was found: One BTS belongs to one operator in China.
Teaching Application
A6 is compatiable and easy to use, it is wildly used in universities for teaching task. Students can learn about signal demodulation and analysis on A6.
