ABSTRACT
To achieve a high level of accuracy from an integrated GPS/INS system, the
carrier-phase observations have to be used to update the integration filter’s
states. It is a prerequisite that the integer ambiguity must be resolved before
using carrier-phase measurements. However, the occurrence of an
undetected cycle slip will significantly degrade the filter’s performance. In
this paper, an algorithm that can effectively detect and identify cycle slips
will be presented. The algorithm uses additional information provided by
the INS, and applies a statistical technique known as the cumulative-sum
(CUSUM) test. Cycle slip decision values can be computed from the INS
predicted position due to the fact that its short-term accuracy is very high.
The CUSUM test is then very sensitive to abrupt changes of mean values,
making it ideal for the detection of cycle slips. Kinematic experiments were
carried out in order to test the effectiveness of the proposed algorithm. The
results indicate that cycle slips can be effectively detected and then
instantaneously corrected using the proposed algorithm. Hence, the
accuracy and performance
