Interference are among the most penalizing error sources in global
positioning system
(GPS) navigation. So far, many effort has been devoted to developing GPS receivers more robust to the radiofrequency environment. Contrary to previous approaches, this paper does not aim at improving the estimation of the GPS pseudoranges between the mobile and the GPS satellites in the presence of interference. As an alternative, we propose to model interference effects as variance jumps affecting the GPS measurements which can be directly detected and compensated at the level of the navigation algorithm. Since the joint detection/estimation of the interference errors and motion parameters is a highly non linear problem, a particle filtering technique is used. An original
particle filter
is developed to improve the detection performance while ensuring a good accuracy of the positioning solution.

...In this paper, we focus on interference which simply result in measurement noise variance jumps [

...As an alternative, particle filtering strategies have been investigated to jointly detect/estimate variance jumps in a timevarying system [

...Table 2 reports the mean detection delay (MDD), the mean square positioning error (MSE), the mean value and the std of the variance jump estimates, denoted {αi}i∈[

...Indeed, the estimates are not only on average closer to the actual values of the {αi}i∈[
