The ZKManet2441 is a ground terminal engineered for long-range video data communication. It comes equipped with an integrated GPS tracking module and a wireless communication module. The airborne GPS module transmits GPS/BD coordinate data to the wireless communication module via a serial port, facilitating seamless transmission. The ground terminal determines the pointing angle by comparing its own latitude and longitude with those of the airborne unit. This alignment ensures that the ground panel antenna consistently points towards the airborne module, optimizing wireless reception and greatly enhancing range. It features a 1T2R dual-antenna system, which includes a high-gain directional antenna for both transmitting and receiving signals, along with an omnidirectional antenna for improved reception, allowing for more efficient signal transmission.
