This is a live map from the <a href="/">galmon.eu</a> project. This map can plot if a fix is possible ('Coverage') or if the positioning, horizontal or vertical precision will be bad (<a href="https://en.wikipedia.org/wiki/Dilution_of_precision_(navigation)">PDOP, HDOP, VDOP</a>). Red blocks indicate a problem even in perfect viewing conditions. Orange means a problem if there are obstructions below 10 degrees above of the horizon, yellow for less than 20 degrees ('urban canyon').

<b>These <a href="https://github.com/ahupowerdns/galmon/blob/master/coverage.cc">calculations are very provisional</a> and might be wrong!</b>
