1. A computer-implemented method for providing a visualization of sightline obstructions, the method comprising: identifying, by one or more computing devices, an approximate position of a receiver antenna; providing, by the one or more computing devices, a rendering of a physical environment surrounding the receiver antenna for display within a user interface, wherein the user interface is provided on a display; accessing, by the one or more computing devices, satellite positional data describing a position of a satellite; determining, by the one or more computing devices, a sightline between the approximate position of the receiver antenna and the position of the satellite; and presenting, by the one or more computing devices, the sightline within the user interface in association with the rendering, wherein the sightline between the receiver antenna and the satellite superimposes the rendering of the physical environment.
