In order to ensure the continuous tracking observation of the satellite and quality of the satellite signal,
the space above the station should be as wide as possible, with no obstacles above the 15° elevation
angle. To reduce the interference of various electromagnetic waves on the GNSS satellite signal, there
should be no strong electromagnetic interference within a range of about 200m around the station, such
as TV towers, microwave stations, and high-voltage transmission lines. To avoid or reduce the
occurrence of multipath effects, the station should be away from terrain and features with strong
reflectors, such as high-rise buildings, water, etc.
