Satellite Communication for Long-Range Drone Connectivity

One-station dual-satellite communication system for unmanned aerial vehicles (UAVs) using two satellites in the same orbit to improve UAV satellite connectivity. It allows UAVs to simultaneously use a traditional wide-beam satellite system and a multi-spot beam high-throughput satellite system. This provides real-time transmission of UAV commands, telemetry, and mission data. The wide-beam satellite ensures reliability while the high-throughput satellite provides higher bandwidth. It allows dynamic resource allocation based on requirements, like critical commands using wide-beam and large data using high-throughput.

Communication system for drones that allows long-range, low-cost, and lightweight communication for cargo drones operating at high altitudes and long distances. The system uses low-orbit satellites for relaying instead of high-orbit satellites. The drone communicates directly with a gateway on the ground, which relays data to low-orbit satellites. The drone also communicates with the satellites directly. This allows using an omnidirectional antenna and reduced power since the satellites are closer. The satellites have wider bandwidth due to Doppler shift. It reduces drone equipment size, cost, and weight compared to high-orbit satellites. The ground station and satellites can provide telemetry and remote control, while images are only downloaded during landing.
