Geocaching was originally similar to the 160-year-old game letterboxing, which uses clues and references to landmarks embedded in stories. Geocaching was conceived shortly after the removal of Selective Availability from the Global Positioning System. Up until this point Military GPS receivers were accurate down to 2 metres while non military GPS units had a build in error factor of around 100 metres. From the date when U.S President Bill Clinton had SA switched off anyone with a GPS could navigate to within 2 metres of a Waypoint.
There is nothing to find at the given Coordinates. Find the answers to the following questions pertaining to Geocaching to locate where the cache is hidden.
S 41° 1A.BCD E 174°4E.FGH
- A = Numerical Value of the month ‘Selective Availability’ was turned off
- B = ( Decrypt )
- C = The 4th digit of the coordinates of the original cache placement
- D = Sum of the digits of the year S A was turned off and the first Geocache was placed.
- E = The number of official Geocaching Container Types ( Statistics may help here)
- F = Geocaching was Original known as GPS S…………. H……… Number of letters in both words
- G = The numerical number of the month GC1KRRB was published
- H = New Zealand’s oldest active Geocache (in Wainuiomata). Last digit of the GC code
Sum Check: A+B+C+D+E+F+G+H = 38
