in the specified temperature. More
details please refer to Chapter 7:
Technical Parameters.
To ensure the quality of continuous tracking satellites
and signals, surveying work should be in open air, while there
should no any obstacle in space above 15° altitude angle; in
order to reduce all kinds of electrical interference to the
GNSS satellite signals. Besides, there should not be strong
electrical interference around within about 200m range, such
as the television tower, microwave stations, high voltage
transmission line. Also, in order to avoid or reduce the
occurrence of multi-path effect, stations should be away from
terrain or geographical objects, which will strong effect
electrical signal, such as high-rise buildings, big pool, etc.
