“…The EKF may not reach the CRLB even in the case of a good initialization. Initial values are chosen from a parametric approach similar to the approach described in (Mušicki & Koch, 2008): the first measurement is used for initialization. It defines a hyperbola as possible emitter locations from which several points are taken.…”

“…The additional AOA measurement can solve the ambiguities appearing in processing TDOA measurements only. Another possibility considers two sensors measuring the FDOA between two frequencies of arrival (Mušicki et al, 2010;Mušicki & Koch, 2008). These measurements can be taken by the same sensors as the TDOA measurements.…”

“…They use the difference in received frequency between two signals from a single transmitter propagated through two different satellites. FDOA is the result of differences in the satellites' oscillator frequency offset and drift, and different Doppler shifts caused by satellite motion [11,14].  Ephemeris Error Compensation (EEC) Algorithms:…”

Global Navigation Satellite System (GNSS) technology is growing fast in our society and new applications are being introduced at an unprecedented pace. The GNSS products provide worldwide and real-time services using precise timing information, positioning and synchronization technologies. Within years, GNSS applications are becoming more accurate and their precision opens doors to a wide range of applications. Nevertheless, these applications are susceptible to disruption in the operation of GNSS receivers when malfunctions, failures or interference occur. This paper's objective is to make an overall analysis of GNSS failure impact on society and therefore make a review of GNSS spectrum protection strategies. In the first three sections of this analysis, we survey GNSS applications, their importance and their criticality. While questioning the criticality of GNSS applications, we evaluate their impact on main critical infrastructures and particularly the risks of critical dependencies in case of failure or interference. In the last two sections, we investigate GNSS spectrum interference in relation to its effects on crucial infrastructures. We review the principal Radio Frequency Interference (RFI) sources leading to GNSS and satellite communications (SATCOM) spectrum issues. Alongside, we study various ways to mitigate RFI. This process is essential to further develop and standardize mitigation techniques and to ensure GNSS spectrum immunity against RFI.

“…Many modern techniques used in passive localization now rely on time and frequency based measurements on different platforms. For example, many techniques are based on the calculation of T/FDOA (time/frequency difference of arrival) [1][2][3][4][5], and scan-based localization techniques use the dates of interception of the main lobe of a rotating emitter [6]. Since the measurements depend on the time on two or more remote platforms, several clocks are needed.…”

Abstract:In Electronic Warfare, and more specifically in the domain of passive localization, accurate time synchronization between platforms is decisive, especially on systems relying on TDOA (time difference of arrival) and FDOA (frequency difference of arrival). This paper investigates this issue by presenting an analysis in terms of final localization performance of an experimental passive localization system based on off-the-shelf components. This system is detailed, as well as the methodology used to carry out the acquisition of real data. This experiment has been realized with two different kinds of clock. The results are analyzed by calculating the Allan deviation and time deviation. The choice of these metrics is explained and their properties are discussed in the scope of an airborne bi-platform passive localization context. Conclusions are drawn regarding the overall localization performance of the system.
