The SGCB series is both for everyone and Scouts working on their GeoCaching Badge (leaders see OSM for activity info). There are 6 caches and whether you start at Crossways or from Burbush car-park, they are best done in an anti-clockwise direction to save more than a little back-tracking. It’s about a 3.5 mile walk round the series from one of the parking areas. The views from Dur Hill Down on a clear day go for miles.
“This cache is on Forestry Commission land and has been placed in accordance with the GAGB – Forestry Commission Agreement. As part of this Agreement, it is not permitted to seek the cache during the hours of darkness”.
Geocaching uses GPS technology which uses satellites. Satellite technology has been crucial for 2 aspects of using GPS location finding.
Firstly, highly accurate digital mapping was required, something far better than any maps we’d had before, and these digital images were taken from satellites.
Secondly, transmitting satellites are required to work out your location. 30 US satellites orbit the earth to allow us to pinpoint our location via GPS. More recently 26 EU satellites make up the Galileo navigation system which is even more accurate than GPS. Many phones are already compatible and use it.
Our devices receive signals from a number of satellites which allow them to work out where we are. But how many are needed for an accurate fix? Clue - its not the number most people think!
