Geocache Description:

Vad är det för grunka? What is this thingy?

(Scroll down for English)

Manicken som står där på bergshällen och ser ut som nån slags raket är i själva verket en fast positionerad GPS-mottagare som tillhör det nationella nätverket SWEPOS. Med långtidsmätningar kan man mäta på millimeternivå för att t.ex se jordskorpans rörelser och för byggarbeten.
Just denna station är en av Sveriges 36 klass A-stationer. Gemensamt för dessa är att de är fastgjora i berggrunden för maximal precision och att de är rustade för maximal tillförlitlighet. Det finns även klass B-stationer, som inte har samma krav.

The strange widget on the bare rock that looks like a rocket is in fact a fixed GPS receiver and is part of the national network SWEPOS. By measuring over time a position can be determined with an accuracy down to millimeters. This is useful for example to monitor the movement of the earths surface, and for construction work.
This particular station is one of 36 class A stations in Sweden. These have in common that they are bolted into the bedrock for maximum precision. They are also installed with maximum reliability in mind. There are also class B stations that don't have as strict requirements.
