It depends on how accurately the bird can measure the round-trip time: 1 us = ca 500' 10 us = ca 1 mile 100us = ca 10 miles 1 ms = ca 100 miles
The arcs are loci of constant round trip time, projected on the globe. -John =============== > My question was on what would be the expected accuracy of the circle's > radius. > > Antonio I8IOV > >>----Messaggio originale---- >>Da: [email protected] >>Data: 20/03/2014 1.21 >> >>They only got one ping from INMARSAT at 64E above the Indian Ocean. >>There was no other ping to triangulate the position. >> >>One ping projects a circle on the Earth.
