The paper presents suggestions on how to carry out receiver autonomous integrity monitoring with global navigation satellite systems’ user equipment in jamming environment by employing 3 alternative methods with the use of indirect measuring techniques during pre-processing and subsequent comparison with threshold values that correspond in a one-to-one manner to user position error, i.e. the ratio of the received signal energy to radio interference power spectral density estimate (the first method), the received signal and its pattern cross-correlation coefficient (the second method), and difference between observable and extrapolated pseudorange estimation (the third method).
