We present the results of a feasibility study on the application of optical quantum communication links to a global navigation satellite system (GNSS) network with reference to the Galileo architecture. As a particularly relevant case, we derive specifications for an inter-satellite quantum key distribution (QKD) network and evaluate its expected performance in terms of achievable key lengths.

One of the method to have a fast acquisition of GNSS signals is the parallel code-phase search, which uses the fast Fourier transform (FFT) to perform the correlation. A problem with this method is the potential sign transition that can happen between two code periods due to data or secondary code and lead to a loss of sensitivity or to the non-detection of the signal. A known straightforward solution consists in using two code periods instead of one for the correlation. However, in addition to increasing the complexity, this solution is not efficient since half of the points calculated are discarded. This led us to look for a more efficient algorithm. The algorithm proposed in this article transforms the initial correlation into two smaller correlations. When the radix-2 FFT is used, the proposed algorithm is more efficient for half of the possible sampling frequencies. It is shown for example that the theoretical number of operations can be reduced by about 21 %, and that the memory resources for an FPGA implementation can be almost halved.

In this paper, the structure of a tracking loop with Extended Kalman Filter (EKF) is analyzed. Particular emphasis is given to the NCO update rule, which is seldom mentioned or studied in previous literature. Furthermore, the structure of an EKF-based software receiver is proposed including the special modules dedicated to the initialization and maintenance of the tracking loop. The EKF-based tracking architecture has been compared with a traditional one based on an FLL/PLL+DLL architecture, and the benefit of the EKF within the tracking stage has been evaluated in terms of final positioning accuracy. Further tests have been carried out to compare the Position-Velocity-Time (PVT) solution of this receiver with the one provided by two commercial receivers: a mass-market GPS module (Ublox LEA-5T) and a professional one (Septentrio PolaRx2e@). The results show that the accuracy in PVT of the software receiver can be remarkably improved if the tracking is designed with a proper EKF architecture and the performance we can achieve is even better than the one obtained by the mass market receiver, even when a simple one-shot least-squares approach is adopted for the computation of the navigation solution.

This paper presents an impulse-radio UWB experimental platform for ranging and positioning in GNSS-challenged environments. The platform is based on the two-way time-of-arrival principle of operation, which reduces architecture complexity and relaxes the synchronization requirements with respect to time-of-arrival or time-difference-of-arrival solutions. The modular architecture of the platform is described together with the design and features of its main components, namely the 5.6-GHz RF front end and the baseband module for measurement and processing. A set of experimental results obtained using the realized platform in an indoor office environment is presented and discussed. The platform provides a maximum range of about 30 m in line-of-sight conditions with an RMSE of the order of 40 cm.

In this paper, the problem of Received Signal Strength (RSS)-based WLAN positioning is newly formulated as a deconvolution problem and three deconvolution methods (namely Least Squares, Weighted Least Squares and Minimum Mean Square Error) are investigated with several RSS path loss models. The deconvolution approaches are compared with the fingerprinting approach in terms of performance and complexity. The main advantage of the deconvolution-based approaches versus the fingerprinting methods is the significant reduction in the size of the training database that need to be stored at the server side (and transferred to the mobile device) for the WLAN-based positioning. We will show that the deconvolution based estimation can decrease of the order of ten times the size of the training database, while still being able to achieve comparable root mean square errors in the distance estimation.

Interference is the major threat to integrity of navigation systems. In this paper, we provide new approaches to localization and characterization operations of GNSS jamming signals in both cooperative and distributed architectures. As for localization, Differential Received Signal Strength (DRSS) and an Extended Kalman Filter (EKF) are exploited. With respect to characterization, two approaches are envisaged, both based on exploiting the Karhunen-Loève Expansion (KLE). In the first, the nodes estimate and reconstruct the received jamming signal and share this data between themselves or with a Fusion Center (FC), which exploits KLE for data aggregation. In the second approach, signal estimation and reconstruction are performed at the FC, thus decreasing the nodes' complexity. The performance of the localization and characterization algorithms are analyzed in terms of Mean Localization Error (MLE) and Mean Square Error (MSE), respectively. Simulation results show that the proposed algorithms provide good performance.

`Onion-peeling' algorithm is a very common technique used to invert Radio Occultation (RO) data in the ionosphere. Because of the implicit assumption of spherical symmetry for the electron density distribution in the ionosphere, the standard Onion-peeling algorithm could give erroneous concentration values in the retrieved electron density profile. In particular, this happens when strong horizontal ionospheric electron density gradients are present, like for example in the Equatorial Ionization Anomaly (EIA) region during high solar activity periods. In this work, using simulated RO TEC data computed by means of the NeQuick2 and IRI2012 ionospheric electron density models and ideal RO geometries, we tried to formulate and evaluate an asymmetry level indicator for quasi-horizontal radio occultation observations. This asymmetry index is based on the electron density variation that a ray may experience along its propagation path (satellite to satellite link) in a RO event. This index is dependent on the occultation geometry and on the azimuth of the occultation plane. Our qualitative assessment shows a good correlation between our asymmetry index and Onion-peeling retrieval errors; i.e. errors produced by Onion-peeling in the retrieval of NmF2 and VTEC are larger at the geographical locations where our asymmetry index indicates high asymmetry in the ionosphere.

Irregular electron content in the ionosphere affects the propagation of Global Navigation Satellite Systems (GNSS) signals with a phenomenon known as scintillation. Ionospheric scintillations are rapid fluctuations in the amplitude and phase of the signal that can lead a receiver to lose lock. In recent years the number of Ionospheric Scintillation Monitoring Receivers (ISMR) have increased dramatically. This paper presents an initial analysis of the effect that interference may have in the calculation of the widely used amplitude scintillation index S4. Interference is one of the growing threats to the performance of GNSS. Our analysis shows that interference may have particular effects on GNSS receivers that can lead them to output an erroneous measurement of the S4 index.

In this paper a one shot receiver for DVB-T positioning is presented. DVB-T SFN signals can be used as Signals-of-Opportunity in urban environment to assist GNSS in case the GNSS-only positioning shows degraded performance. The normal mechanism of DVB-T positioning involves a tracking stage to refine the coarse delay estimation obtained by the acquisition stage. However due to the high SNR of DVB-T signals, the delay estimation can be refined by some simple interpolation methods with lower complexity and power consumption. Two different interpolation methods, linear interpolation and sinc interpolation, are analysed in the paper. Simulation results show that the one shot receiver proposed in this paper behaves as a tracking-based receiver, but exhibits a lower complexity.
