Phase Comparison RNAV

Phase comparison looks at how far apart different waves having the same frequency are “apart” in their phase. A good way of thinking about this is different times zones; while France and England use the same clocks (and they both take 12 hours for the hour hand to do one revolution) they are one hour “apart”. This comparison would not be possible if the days were different lengths – for example on Mars and Earth.

Note that amplitude makes no difference – you can still compare clocks on Earth even if they are different sizes.
