synchronization source for the measurement device. The GPS receiver, available as an accessory, is
used as outdoor antenna to process data from multiple GPS satellites simultaneously.

Choosing a mounting location
For a correct operation the GPS receiver requires data from at least 3 satellites at the same time.
Therefore position the receiver so that the clearest possible view of the sky and horizon in all direction is
obtained. This can be on the roof of a building, at best without reception being restricted by other
buildings or obstacles. Avoid mounting the receiver next to large areas of conductible material, as this
may cause poor signal reception. It should be also not closer than 1 meter away from any other antenna.
If lightning protection is required, this must be
provided by the user himself.
