The ZKManet2441 is a ground terminal specifically engineered for long-distance video data transmission. It features 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 computes the pointing angle by comparing its own latitude and longitude with those of the airborne module. This alignment ensures that your ground panel antenna remains consistently oriented towards the airborne module, optimizing wireless reception and significantly extending the operational range. It utilizes a 1T2R dual-antenna system, incorporating a high-gain directional antenna for both sending and receiving signals, alongside an omnidirectional antenna for enhanced signal reception, thereby improving overall transmission effectiveness.
