多频带GNSS接收机可跟踪所有可能存在的卫星系统发射的所有信号,意味着接收机可“看到”尽可能多的卫星,在挑战性条件下表现稳健,比如机械、建筑物、岩石或植被周围。
GNSS vs GPS So what is the difference between a GPS and a GNSS receiver? A simple GPS receiver only makes use of one global navigation satellite system, while multi-constellation GNSS receivers get information from many such systems at the same time. This allows them to "see" much more...
