overhead observation station shall be open, without flaky
barriers above 15° elevating angle; in order to diminish the
interference of electromagnetic wave to GNSS satellite signals,
the observation station shall be free form strong
electromagnetic wave within the range of 200m, such as
television tower, microware station and high-voltage
transmission line; in order to avoid or reduce multipath effect,
the observation station shall be far away from the terrain and
ground features with strong reflection against electromagnetic
wave signal, such as high-rise buildings, waters, etc.
