The ZKManet2401 is a ground terminal specifically crafted for long-range video data transmission. It incorporates an integrated GPS tracking module along with a wireless communication module. The airborne GPS module transmits GPS/BD coordinate data to the wireless communication module via a serial port, enabling seamless transmission. The ground terminal determines the pointing angle by comparing its own latitude and longitude with those of the airborne module. This alignment ensures that the ground panel antenna consistently points towards the airborne module, optimizing wireless reception and significantly enhancing the operational range. It features a 1T2R dual-antenna system, utilizing a high-gain directional antenna for both transmitting and receiving, as well as an omnidirectional antenna for improved signal reception, thereby enhancing overall transmission efficiency.
