Title: REAL-TIME ARAIM USING GPS, GLONASS, AND GALILEO

Show moreSince the inception of GPS, satellite navigation has been a widely used means of navigation for both military and civilian users on the ground and in the air. GPS is capable of providing highly accurate positioning and timing information to users around the globe. However, for certain applications, providing high-accuracy position estimates is not sufficient. Because satellites are susceptible to faults, the safety, or integrity, of the position estimates is also of concern, especially in civilian aviation where safety is critical. As such, receiver autonomous integrity monitoring (RAIM) can be used in order to detect and potentially exclude these faults and guarantee the safety of the position estimate. RAIM has been capable of supporting horizontal aircraft navigation using GPS for decades and has proven to be a useful tool. Now, as more global navigation satellite systems (GNSS) become available, the potential for advanced RAIM (ARAIM) to support vertical guidance for aircraft using multiple constellations has become an area of great interest. In this work, the ARAIM methodology is discussed, and the procedure is outlined, including protection level calculation, fault detection, and exclusion. The procedure is then implemented in a real-time ARAIM prototype. While GPS and Galileo aim to provide worldwide coverage for vertical guidance by 2020 when Galileo is fully operational, ARAIM performance can be examined at present using the current full-strength GPS and GLONASS constellations. This prototype performs position estimation and ARAIM using measurements from the current GPS, GLONASS, and partial Galileo constellations. ARAIM results in a variety of different GNSS scenarios are examined. Furthermore, this work investigates two methods of improving the computational efficiency of the ARAIM algorithm: satellite selection and fault mode grouping.

Title: CHARACTERIZING GPS PHASE LOCK LOOP PERFORMANCE IN WIDEBAND INTERFERENCE USING THE DISCRIMINATOR OUTPUT DISTRIBUTION

Show moreThe use of the Global Positioning System (GPS) has accelerated in recent years. In its inception, GPS was used exclusively by the military for navigation. Today, with the emergence of extremely capable electronics and microprocessors, GPS has been integrated into many aspects of life. It is currently widely used by both the military and various civilian industries for applications that require navigation as well as precise timing. Some applications of GPS include ground vehicle and aircraft navigation, banking, power transmission, and agriculture. As a result, disruptions in GPS availability have the potential to disrupt many services and industries around the globe, and even threaten the safety of life. Reliable operation can be interrupted by radio frequency interference (RFI), which can come from natural and manufactured sources. This work describes new techniques to evaluate the performance of GPS receivers that may be subjected to RFI events. The example application motivating this work is Ground Based Augmentation System (GBAS) reference station receivers subjected to broadband interference, for example, from nearby use of personal privacy devices (PPDs). PPDs most commonly emit broadband interference, and GBAS ground based reference receivers have expe- rienced tracking discontinuities as a result [Pul12]. These events can cause navigation service interruptions to aircraft on nal approach. To ensure continuity of the nav- igation service, GBAS reference stations must be able to track GPS signals in the presence of wideband interference. The objective of this work is to develop the PLL analysis tools required to design PLLs capable of tracking through RFI events, while reducing the need for time-consuming simulations and experimental validation. Instead, simulation and experimental validation can be reserved for PLL designs which are much more likely to be successful. The techniques described in this work are valid for any GPS application in which the receiver cannot tolerate cycle slips in the phase-lock loop (PLL). The methodology is directly applicable to ground-based reference receivers for differential GPS systems, as well as other ground-based receivers that require high continuity of service. It is also relevant to moving receivers, if the additional dynamic stresses on the PLL are also taken into account. The PLL discriminator output (DO) distribution is used to characterize GPS PLL tracking performance, in contrast to the phase jitter metric widely used in prior work and literature. Both the DO variance and the bias on the mean of the DO distribution are shown to be superior to the jitter metric in predicting phase-lock. And, it is shown that the bias in the DO mean is the most effective measure of cycle slip probability. Studying the discriminator output distribution also provides a means of comparing different techniques to extend PLL averaging time beyond the length of a navigation data bit, without time-consuming direct simulation and experimental validation. Experimental results are presented to validate the theoretical analysis and simulations. The observed tracking results are consistent with the theoretically predicted system performance. The DO bias is superior to the variance metric in its ability to predict loss of phase-lock.

Show moreThe Scintillation Auroral GPS Array (SAGA), comprising six kilometer-spaced receivers located in Poker Flat, Alaska, has been deployed for four years to study high latitude scintillation effects on L1 and L2C frequency Global Positioning System (GPS) signals. These scintillations disrupt the GPS signals received on the earth, affecting navigation services. Scintillation is associated with the variations in plasma densities known as irregularities, present in the ionosphere. Research on scintillation has been done from the past using different instruments and techniques, and for multiple purposes. One important prior effort is automated detection of the scintillation of L1 frequency GPS signals. Other successful research includes estimating the drift velocity of irregularities, anisotropy, height and thickness of the scattering layer. It is important to check before studying the properties of irregularities whether the sensors can detect the scintillations happening in the E or F region. In other words, it is essential to check that the sensors are sensitive not only to F region scintillations but also to the E region scintillations. The purpose of this work is to identify the ionospheric region, E or F, which is responsible for the scintillation on the L1 and L2C GPS signals. The scintillations of these GPS signals are further classified based on the type of scintillation i.e., phase scintillation and amplitude scintillation. The scintillation events are categorized as amplitude, phase, or both on L1 or L2C frequency occurring in the E or F region. Using the automated scintillation detection routine, a complete list of phase and amplitude scintillations on all days for both the frequencies L1/L2C in the years 2014 and 2015 is created. The highly scintillating days for 2014 and 2015 are sorted and the irregularities layer associated with these scintillation events are identified. The Poker Flat Incoherent Scatter Radar (PFISR) and All Sky Camera images are used to develop the process of identifying the ionospheric region. The electron density from PFISR is assumed to be an essential parameter to determine the E/F layer irregularities. The All Sky Camera provides the red auroral brightness and the green auroral brightness, where red aurora implies F region and the green aurora implies E region. A summary of a subset of the scintillation events occurring on the highly scintillating days in 2014 and 2015 is provided through this work. It is found that phase scintillation is occurring more predominantly in the high latitudes than the amplitude scintillation. A number of these are attributed to E and F region irregularities. In future, the scintillation events obtained from this work will be used to study the E and F layers irregularities and properties in detail.
