Reducing the jitters: How a chip-scale atomic clock can help mitigate broadband interference

Popis výsledku v původním jazyce

Currently installed Local Area Augmentation System (LAAS) ground receivers have experienced a number of disruptions in GPS signal tracking due to radio frequency interference (RFI). The main sources of RFI were coming from the illegal use of jammers (also known as personal privacy devices (PPD) inside vehicles driving by the ground installations. Recently, a number of researchers have studied typical properties of popular PPDs found in the market and have concluded that the effect of PPD interference onthe GPS signal is nearly equivalent to that of a wideband signal jammer, to which the current GPS signal is most vulnerable. For GPS receivers in general, wide tracking loop bandwidths are used to accommodate the change in signal frequencies and phasescaused by user dynamics. Unfortunately, wide bandwidths also allow more noise to enter into the tracking loop, which will be problematic when wideband inference exists. The general approach to mitigate wideband interference is to reduce t
