Methods, systems, and computer program products are provided for analyzing a Global Navigation Satellite System (GNSS) receiver (120). The method includes receiving electronic diagnostic information from the GNSS receiver (120), the diagnostic information including observations at different times of signal strength of one or more satellites (130) at each point in a visible sky. The method includes building a flat map of the visible sky including a track of the one or more satellites (130). The method includes calculating, for each point in the visible sky of the flat map, an aggregated signal strength of the one or more satellites (130) over a predetermined interval. The method includes generating a heat map over the flat map of the visible sky and displaying a visualization of a flat heat map (700). |
