T-ASJ10 GNSS spoofing and jamming security device
GNSS anti-interference security protection solution
The T-ASJ10 GNSS spoofing and jamming security device utilizes advanced anti-spoofing and jamming technology to effectively detect and identify spoofing jamming signals, quickly shutting down abnormal signals and isolating them to eliminate the effects of spoofing and jamming. The T-ASJ10 antenna features a high-gain, wide-pattern beam for more stable wide-angle circular polarization performance. A multi-feedback design ensures a stable phase center and ensures multi-system tracking accuracy. The antenna's LNA exhibits excellent out-of-band rejection, suppressing unwanted electromagnetic interference and providing a stable and reliable GNSS signal. It also effectively mitigates the risk of receiver lock loss in complex electromagnetic environments, such as urban areas and base stations. The device utilizes a redundant power supply for enhanced reliability, a screen that displays extensive system information, and a dual-color LED that intuitively displays various warning messages.
Applicable fields: power transmission, power generation, substation, finance and securities, communications, transportation, national defense, etc.
