	%X Radio interference is one of the major concerns in
using the global positioning system (GPS) for civilian and military
applications. Interference signals are produced not only through
all electronic systems but also illegal jammers. Among different
types of interferences, continuous wave (CW) interference has strong
adverse impacts on the quality of the received signal. In this paper,
we make more detailed analysis for CW interference effects on
GPS signal quality. Based on the C/A code spectrum lines, the
influence of CW interference on the acquisition performance of
GPS receivers is further analysed. This influence is supported by
simulation results using GPS software receiver. As the most important
user parameter of GPS receivers, the mathematical expression of bit
error probability is also derived in the presence of CW interference,
and the expression is consistent with the Monte Carlo simulation
results. The research on CW interference provides some theoretical
gist and new thoughts on monitoring the radio noise environment and
improving the anti-jamming ability of GPS receivers.
