Lecture: GNSS Threats: Receiver Level Defenses
GNSS signal reception is vulnerable to several forms of interference which can be either intentional or unintentional in nature. The power of strong RF interference can overwhelm the much weaker GNSS signals, significantly degrading the performance of a GNSS receiver. In this lecture, different approaches to mitigate the impact of RF interference and jamming at the receiver level are discussed. The problem of interference detection and mitigation is introduced and several approaches, such as notch filtering and pulse blanking, are discussed. Interference detection and mitigation are explained in terms of detection and estimation theory and general concepts for the design of detection and mitigation techniques are provided. Practical examples are used to clarify theoretical concepts.

 

Lab on GNSS Signal Processing

The goal of this lab is to provide the students with hands-on experience of the various signal processing stages of a GNSS receiver. The experiments conducted during the lab will complement the notions introduced during the lectures and will allow the students to directly experiment on real GNSS data. 
The lab is divided in three parts that will analyze acquisition, tracking and measurement generation. The students will be provided with a short data set containing baseband GPS L1 C/A and Galileo E1 signals. Signal acquisition and tracking will be performed on the provided dataset. Some basic Matlab scripts for acquiring and tracking GPS L1 C/A signals will be also provided.

The correlators provided by the tracking loops will be used to extract the Time Of Week (TOW) that, combined with other tracking loop outputs, will be used to generate pseudorange measurements. Doppler and carrier phase measurements will also be discussed.

The lab is divided into exercises that require the modification of the basic acquisition and tracking scripts and the addition of new functionalities.

The radiofrequency link plays a significant role in the performance of communication and navigation systems. Information is conveyed thanks to the use of carrier modulation often combined with channel coding. Several RF carriers can share the same radio resource thanks to multiple access techniques. The lecture introduces the various concepts and waveforms relevant for satellite links, in particular with navigation systems. The main parameters and factors conditioning the link performance are discussed.

- Space Communications/Positioning with Communication Systems.
The lecture gives a broad introduction to satellite communications: system architecture depending on application, type of orbits of interest, evolution in terms of technology and services, etc. This overview supports the description of communication satellite based augmentation systems (SBAS) to augment the performances of GNSS. Integrated Satcom/Satnav applications examples and principles of positioning using various communication systems technologies (WiFi, UWB, etc conclude the presentation.

Lectures:

 

- Satellite-based Augmentation System (SBAS) and Receiver Autonomous Integrity Monitoring (RAIM, ARAIM)
 

Safety-of-Life (SoL) related applications (e.g. Aviation, Maritime, Rail) have dedicated requirements that demand specific solutions. Space-Based-Augmentation-Systems (SBAS) and Receiver Autonomous Integrity Monitoring (RAIM) have been developed in order to exploit GNSS signals and services for SoL applications without requiring at the location where the operation shall be conducted local ground installations. This lecture introduces relevant SoL performance metrics and requirements for aviation and maritime users, followed by an outline of the SBAS and RAIM principles, their existing implementations and achieved performance levels. In addition also the future evolution of SBAS towards Dual Frequency Multi Constellation (DFMC) SBAS is presented together with its expected benefits for users. Exploiting the existing interoperability of GNSS signals can enable Advanced RAIM (ARAIM) solutions in the future. These are currently engineered at international level for the provision of horizontal (H-ARAIM) and vertical (V-ARAIM) capabilities. The principles and advantages of ARAIM are discussed in this lecture together with possible implementation solutions.

 

- GNSS Space Service Volume and Deep Space Navigation

The vast majority of GNSS users are located at the surface of the earth or close to it and GNSS systems are primarily designed to serve these users. However, GNSS signal emissions also extend beyond the earth and are exploited also for positioning and operating satellites up to Geostationary Orbit and even beyond. This lecture describes the benefits of GNSS signals for space users and their specific user and application needs. Particular attention is paid to the interoperable GNSS Space Service Volume (SSV) which can significantly enhance the GNSS signal availability for satellites at altitudes above 8000 km. Concepts allowing for Deep Space Navigation are outlined in this lecture.

Lectures:
- GNSS Effects for Aviation

This lecture describes the use of Global Navigation Satellite Systems (GNSS) to support air navigation.  Particular attention will be paid to challenges that can affect the availability and safety of GNSS based navigation.  The currently operating systems that augment the Global Positioning System (GPS) will be described.  These are Aircraft Based Augmentation Systems (ABAS), Ground Based Augmentation Systems (GBAS), and Satellite Based Augmentation Systems (SBAS).  They support differing flight operations and different regions of operations.  Each method is described in detail and how it overcomes the challenges to provide suitable guidance.


- Cyber Security for Civil Navigation
The effects of radio frequency interference (RFI) is one of the largest challenges facing satellite navigation. RFI can overwhelm the desired signals and lead to a loss of navigation.  Even more concerning, is the possibility that undesired signals can be interpreted as the intended signals, leading to corrupted positioning that may go undetected by the user.  This latter spoofing threat may be inadvertent or part of a deliberate attack. The navigation community is working on several powerful technologies to overcome these dangers. These solutions include internal receiver validity checks, advanced receiver autonomous integrity monitoring (ARAIM),  antenna based detection, and comparison to other sensors (such as accelerometers).  ARAIM combats spoofing, because it is difficult to simultaneously replace all of the received signals with counterfeit signals.  However, all of these approaches have limitation. The lecture will describe the threats as well as the trade-offs between the various proposed solutions.
