Galileo Masterclass Brazil (GMB) 2022

 

The GMB 2022 is a comprehensive 7 day course on global navigation satellite systems (GNSS) signal and data processing for undergraduate and graduate students as well as professionals from industry and authorities. The course will focus on the European GNSS (EGNSS), Galileo and the European Geostationary Navigation Overlay Service (EGNOS). It contains 14 lectures starting from GNSS signals and basic signal processing up to advanced data processing and positioning techniques. Additionally, 6 laboratory sessions are offered to apply and train the material of the lectures and to get hands on GNSS signal and data processing techniques. Furthermore, expert invited talks will introduce advanced features of the Galileo system and EGNOS and specific topics related to clocks, orbits, and ionosphere effects, as well as an overview on the European Space Programs including Galileo, EGNOS, and Copernicus. Besides lectures and laboratory sessions a technical visit to the Eusebio site of the National Institute of Space Science (INPE) will be offered.

The main course language is English, with a few lectures offered in Portuguese.

The lecturers and invited experts of the GMB 2022 are all international experts in their specific fields with long-term experience in GNSS signal and data processing as well as system engineering.

The GMB 2022 will take place from 29/08/2022 till 06/09/2022 at the Federal University of Ceará (UFC) in Fortaleza, Brazil. It will be organized as a hybrid event and it will be free of charge with possibilities to participate on site or online.

The GMB 2022 is organized by the Galileo Information Center (GIC) in Brazil.

 

Topics and Learning Content

 

1. INTRODUCTION TO GNSS

(GPS, Galileo, GLONASS, BeiDou) GNSS concept. Historical review. GNSS segments and signals. Similarities and differences between GNSS Precisions / accuracies that can be expected.

 

2. GNSS SIGNALS
Multiple access, spread spectrum ranging , modulations, chip pulse shapes, signal multiplexing, GNSS signal design criteria, propagation aspects.

 

3. GNSS SIGNAL PROCESSING

Signal acquisition, carrier and code tracking, tracking loop design, GNSS receiver design, performance of tracking loops.

 

4. OBSERVABLE GNSS AND ITS COMBINATIONS
Review of the GNSS code and carrier phase measurements. First analysis of the content of the GNSS measures by combinations of observables. Detection of jumps and discontinuities of the carrier-phase measurements (i.e. cycle-slips). Smoothing the code pseudorange with the carrier-phase (Hatch filter). Analysis of the multipath of the code.

 

5. OVERVIEW GNSS POSITIONING TECHNIQUES
A first review of the different positioning techniques by means of satellite signals. Standalone positioning with code pseudorange (i.e. Standard Positioning Service) and differential positioning with smoothed code (DGNSS). Precise positioning with code and carrier phase, Real Time Kinematics (RTK) and Precise Point Positioning (PPP). Commercial services.

 

6. COORDINATES AND TIME REFERENCE SYSTEMS
Reference systems and frames. Transformation between celestial and terrestrial systems. Ellipsoidal coordinates, datums and transformations between systems of coordinates. Different types of time: Solar, Sidereal and atomic. Galileo System Time and comparative with GPS Time and UTC. Atomic clocks in the Galileo satellites: types and characteristics.

7. SATELLITE ORBITS AND CLOCKS
Elliptical orbits and Keplerian elements. Perturbed orbit and osculatrix elements. Calculation of satellites coordinates and clock drifts, characterising their associated errors. Computation algorithms from the broadcast navigation message and from the precise files (SP3 and CLK) from IGS. Calculation of satellite coordinates starting from the Almanac.

 

8. PSEUDORANGE MODELING
Terms to consider: geometric distance, relativistic effects, ionospheric delays (including study of the NeQuickG and comparison with ionospheric models used in other GNSS constellations (e.g. Klobuchar model) and from the International GNSS Service (IGS), tropospheric delays, instrumental delays, multipath, antenna phase centre corrections (from ANTEX files). Qualitative and numerical analysis of the pseudorange modelling.

 

9. NAVIGATION EQUATIONS AND ITS RESOLUTION
Understating the system of equations used for determining the coordinates and time from code pseudorange measurements (Standard Point Positioning). Resolution by least squares. Conceptual view of the Kalman filter.

 

10. HIGH ACCURACY NAVIGATION
Specifically, Precise Point Positioning (PPP). Modelling needs of the observables, both code and phase. Resolution of the carrier-phase ambiguity: floating versus fixing ambiguities. State of the art: PPP Ambiguity Resolution and the use of the ionosphere to accelerate the convergence of the navigation filter (Fast-PPP).

 

11. AUGMENTATION SYSTEMS (GBAS and SBAS)
Introduction to Augmentation Systems, the Integrity concept. Introduction to the Ground Based Augmentation Systems (GBAS). Introduction to the Satellite Based Augmentation Systems (SBAS) and with the focus on the European Geostationary Navigation Overlay Service (EGNOS).
