Only Serial Data Input (No Video Interface)

モード: Point To MultiPoint (1To10)

The GCS (Master) Connect Full-Duplex To 10 無人航空機 (Clients)

The UAV fly simultaneously next to each other. as SWARM.

動作電圧: 12-36ワシントンDCで
Maximum acceleration: 4g
Airspeed: <1000 km/h
Without any GNSS , Wifi, BT

Requirment Number: 200~250unit

With STAR architecture, we don’t need mesh.

We want to control 10 Uav by one GCS, Every UAV has 2xRS232, in Ground side, we have 20xRS232, Point to MultiPoint only.
