four-element anti-jamming navigation device with requencies supported  B1/L1/E1 

This is a four-element anti-jamming navigation device supporting the B1, L1, and E1 frequency bands. It is capable of mitigating various types of interference—including wideband, narrowband, pulse, and frequency-hopping signals—and can suppress interference originating from one to three directions. Featuring a low-cost, compact, and lightweight design, the device meets high-precision navigation requirements in complex environments and is widely used in fields such as UAV navigation, electronic warfare, autonomous driving, and high-precision surveying and mapping.
