Abstract

A beacon system includes emitter devices, driver circuitry configured for controlling the emitter devices, and at least one processor programmed to receive and process one or more inputs and control the driver circuitry to actuate the emitter devices. In an example embodiment, the emitter devices include visible light sources that are oriented to provide omni-directional visibility for the beacon system. In an example embodiment, components of the beacon system including the emitter devices, driver circuitry and at least one processor are configured such that in a space environment heat generated by the beacon system is dissipated sufficiently well to prevent the beacon system from overheating.
