Welcome to the GNSS Positioning Performance Monitor.

These heatmaps are a depth-based representation of the East and North positional errors. These are tests for the accuracy
of these constellations. The darker the color, the more often we received data corresponding to that point.

Click on the legend icons to remove a constellation from the graphs. Drag over the graph to zoom in.
To zoom out, double-click on the graph. The number next to each legend icon is the value of the data collected.
In this graph the data collected is the accuracy of each constellation, focused on their vertical (or North) position.
