An optimal design of GNSS interference localisation wireless security network based on time-difference of arrivals for the Arlanda international airport

Abstract: Today, most of the aircrafts are navigated by global navigation satellite systems (GNSSs). Landing is a dangerous phase of a flight especially when an airport runway is not clearly seen from the aircrafts. In such cases, GNSSs are useful for a safe landing under the circumstances that healthy signals, free of any interference, reach to GNSSs receiver antennas mounted on the aircrafts. This shows the importance of establishing GNSS interference localisation security networks around airports. Designing a good co… Show more

“…When the VCM is selected for optimisation, its direct mathematical relation with the coordinates of the MSs is needed. To derive it, let us expand the VCM by the Taylor series for a node and four MSs of M, N, O and P (see [ 35 , 36 , 40 , 41 , 42 , 43 ]): where is the estimated VCM of the node of the initial design, and are the coordinate updates to the initial locations of the MSs, and and are, respectively, the partial derivatives of the VCM with respect to the coordinates of the i th MS, with the following expressions (see [ 35 , 36 ]): where the elements of and , are partial derivatives of A or the second-order partial derivatives of the observables. Note that the first-order derivative is taken with respect to the transmitter coordinates and the second-order one with respect to x i and y i -coordinates of the i th MSs.…”
