APEX-M9301 Ground Station Data Link

The APEX-M9301 is a ground station data link with an integrated automatic tracking antenna, built to hold a long-range link with airborne radios. Operating at 1200~1300MHz (70~6000MHz customizable) with 2T2R channels and 2*25W output power, it delivers up to 150Mbps at 10MHz and up to 250Mbps at 20MHz over a communication distance of 50~100km(Air to ground LOS), 10~20km (Ground to ground LOS).

The ground station supports point to point, point to multipoint and MESH self-organizing networking, with network nodes of not less than 64 and relay hops of not less than 9. Adaptive BPSK/QPSK/16QAM/64QAM modulation, AES128/256 and SM4 encryption, optional frequency hopping at 1000 hops/second and optional intelligent frequency selecting give the link strong anti-interference ability, and the integrated automatic tracking antenna adjusts itself to the position of the drone for fully automatic tracking.

Image transmission and LORA dual link communication keep the GPS data of the airborne module updated in time. The unit is a rugged field device: IP65 protection level, 360*280*100mm, 10.5kg(w/battery), DC 22-26V power supply, <300W power consumption and 3~4hours working time, with a network interface, PTT voice intercom and optional HDMI interface.

Application Scenarios

1) Long-Range UAV Ground Station Link

As the ground end of a drone data link, the APEX-M9301 uses its automatic tracking antenna to follow the drone and hold the link over 50~100km air-to-ground line of sight, carrying image transmission alongside the LORA link so the airborne module's GPS data stays current.

2) Multi-Drone MESH Operations

For operations with several airborne nodes, the APEX-M9301 anchors a MESH self-organizing network of not less than 64 nodes and not less than 9 relay hops, in point to point, point to multipoint or MESH mode.

3) Anti-Interference Field Deployment

For deployment in contested RF environments, the APEX-M9301 combines frequency hopping and intelligent frequency selection with AES128/256 and SM4 encryption, keeping the ground-to-air link up while the tracking antenna follows the drone automatically.
