Another Geocache at a Trig Point and an ideal spot for a little "science" along with the normal geocaching activities.
Have you ever wondered about the accuracy of your GPS and why the co-ordinates for a cache never seem exactly right?
This cache has been set up not only to find, but also to help in a scientific study into the deviation of GPS position measurements. You will need small fingers or something like a pencil to extract the cache from it's hidy hole. There is a small pull-in at the side of the road about 10 metres from the cache but at times the road is quite busy. Other parking, only about 200 metres from the cache, is on the Warwick Technology Park at N52 16.257, W001 33.756 but is only available outside normal working hours due to lack of parking for employees at the park
Please take the time to log the co-ordinates of the cache and note the number of satellites you are receiving and also altitude if possible. These details can then be recorded via the web site at "Geodrift.com"
A visit to the web site will also explian how & why measurements can vary by several metres. Earlier problems with entering data in feet are supposed to have been rectified but it's probably better to convert your readings to metres before entering them on the website. The "Station" number required is the same as the ID Number for this cache - ie GC156KX. If you don't want to log your data onto the site just leave sufficient info in your visit log, including make & model of your GPS'r and we'll enter it for you.
We had 12 satellites with an accuracy of 5.9 feet and altitude of 63 metres averaged over 450 readings from our Garmin eTrex HC.
