The posted coordinates of this cache DO NOT indicate it's true
location. To determine where this cache is you will need to
think like a GPS receiver by measuring the distance from several
"satellites" and then computing the location of GZ. You will
employ
trilateration
techniques through mathematics, geometry or plain old fashioned
guesswork. Here's a picture that may help you get
started:
But if I were you, I would break out my compass and a map of the
city. So let's get to work!
I have provided the waypoints of four geostationary satellites,
three of which are required to locate your position in 2D.
The fourth will help you determine if any errors have crept into
your calculations or map work. The distance from GZ to each
satellite can be calculated using the indicated information visible
at the listed coordinates.
The final cache is hidden in typical inner city nano
fashion. There are no swaps and no pencil so bring your
preferred writing implement with you. No prize for FTF - just
the glory of beating everyone else to what I am hoping is a
reasonably challenging cache!
