Choosing An Installation Site For The Station - Husky MP2500 Pocket Manual

Choosing an installation site for the station

Choose a site whose position is accurately known and offering an open
view of the sky in all directions. In fact, the presence of buildings or
vegetation in the vicinity:
- will hinder GPS reception for low elevation angles, and so will
reduce the number of satellites visible from the station
- will bring about multi-path effects likely to impair the system's
accuracy.

Check for the absence of obstacles in the direction of the working area.
Their presence nearby is liable to reduce the coverage of the UHF
radio link (U-LINK).
