AVIATION ANTENNA
KT-140FA anti-jamming GNSS receiver(2024)
KT-140FA integrated anti-jamming antenna satellite receiving unit can receive GPS-L1 at the same time1+BDS-B1perhaps BDS-B1+GLONASS-L1Satellite navigation signal can realize single system and joint positioning navigation; can realize GPS-L1+BDS-B1perhaps BDS-B1Anti-interference function of the signal of the + GLONASS. The anti-interference antenna integrates anti-interference RF chip, medium frequency filter, four-channel ADC, anti-interference digital processing chip, DAC, upconversion mixer, radio frequency converter, RF selection switch and switch, MCU and other components, supporting GPS-L1+BDS-B1perhaps BDS-B1+GLONASS-L1Frequency point four-array element broadband anti-interference function.
The main functions of the anti-interference antenna are as follows:
A) BDS-B1,GPS-L1And GLONASS-L1Satellite signal;
B) Up to three incoming GPS-L1 can be inhibited1+BDS-B1perhaps BDS-B1+GLONASS-L1Frequency band harmonic, sweep, pulse, white noise, frequency modulation, amplitude modulation, phase modulation and other broadband, narrowband and other types of interference;
C) Can receive external input control instructions, with controlled direct through function;
D) Direct power access function;
