所有GNSS乐队的干扰
如果未能GNSS接收机跟踪卫星,this may be because RTK solutions are getting stuck in 'Float' or taking longer to converge to 'Fixed'. Interference may be occurring on one or more of your GNSS bands. In addition to harmonics of signals like local TV or radio stations, there are now also USD10 GNSS jammers on the market that interfere with these signals too! JAVAD's TRIUMPH-VS shows interference by analysing signals before RF and after digital sections and quantifies how much interference is present.
The GNSS spectrum analyzer feature of TRIUMPH-VS does much more than a generic USD30,000 spectrum analyzer.
TRIUMPH-VS not only scans the GNSS bands and shows the shape and frequencies of the interferences, but it also quantifies the magnitude of the interferences in two distinct and complementary ways: a) by analyzing the analog signal and determining the 'Interference Magnitude' and b) by analyzing the S/N (Signal-to-Noise ratio) of all satellites' signals after they are digitized and processed (after code and carrier correlations) and determining the 'Satellites S/N loss' due to interferences.
通过分析在数字化之前,通过分析我们可以应用于GNSS信号的增益量来确定“干扰幅度”。存在的干扰越多,我们可以放大信号越少,以避免饱和度。我们可以通过将实际放大幅度与我们的标称放大幅度进行比较来确定“干扰幅度”(不存在干扰时)。
通过将每个卫星的实际测量的S / N与其在该仰角处的标称S / N的标称S / N的标称S / N进行比较,然后对所有卫星信号进行平均来确定'卫星S / N损耗'。
胜利不仅分析和显示干扰,它还具有消除带内干扰的带内的干扰抑制选项。
