Abstract: A remote station and method for rendering a ground plane over video feed are provided. The remote station comprises a processor, a communication interface for communicating with an unmanned vehicle (UV), and a non-transitory memory device storing a communications module. The communications module comprises machine-readable instructions that, when executed by the processor, causes the processor to render a ground plane over video feed. The method comprises receiving a video feed from a camera on a UV, receiving from the UV telemetry information of the camera, receiving from the camera a zoom factor of the camera, calculating a horizon of the camera at a UV controller of the UV, and rendering the horizon as an overlay image on the video feed at a display of the UV controller.

Abstract: A network node 102 capable of detecting how many parties have collided during attempts to transmit on a bus 108. If more than one party has been detected to collide, the node 102 selects a backoff window from a larger randomized group of possible backoff windows than if the node had collided with only one other party. In this way, delays due to multiple parties colliding are minimized.

Abstract: A network having a number of terminals connected by a hub includes managing data transmission collisions by distinguishing among the terminals following a transmission. In the preferred embodiment, the terminals are arranged in a star configuration and the hub is an Ethernet hub that forwards a data packet from a terminal to all of the remaining terminals. A data packet is stored in memory while it is transmitted to all of the other terminals in the collision domain. If a collision is detected in forwarding the data packet, the transmission is completed to the collision-free terminals, thereby isolating subsequent forwarding of the data packet to the one or more collision-inducing terminals. When a no-carrier condition is sensed, the data packet is retransmitted to the one or more collision-inducing terminals.
