Eligibility:
For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.
Aim
The aim of this course is to provide a fundamental understanding of the principles of satellite-based positioning systems and specific knowledge about existing and planned Global Navigation Satellite Systems (GNSS) and their applications.
Goal
At the end of the course the students shall have reached a thorough understanding of the principles of Global Navigation Satellite Systems (GNSS). The students shall understand the mathematical and physical models included in scientific GNSS data analysis. The students shall be able to do observations using GNSS equipment and the corresponding data analysis.
Content
This course will introduce the student to the fundamentals of GNSS and give an overview of a wide range of different GNSS applications.
The basic principles of satellite-based positioning will be studied. We will introduce the reference coordinate and time system, satellite orbital motion, signal propagation, and the GNSS signal structure. The mathematical models for pseudo-range and carrier phase-based modes of positioning for both absolute and relative positioning implementations will be developed. The principles will be illustrated using toolkits for GNSS data analysis
Especially, we focus on the principles of positioning using existing GNSS (i.e. GPS, GLONASS, and Galileo).
We will make a systematic study of factors limiting the accuracy. Especially atmospheric, satellite orbital and other random and non-random error are discussed. Methods to mitigate these individual sources of error will be presented. The use of different observational modes are described and motivated. The concepts of space-based and terrestrial augmentation systems (e.g. EGNOS and WAAS) will be thoroughly addressed. The augmentation systems are used to improve the accuracy and reliability of GNSS. We will define the word integrity which is associated with the quality control of GNSS.
The students will be able to learn a GNSS software package developed for scientific applications with accuracy requirements for relative positioning on the order of a few millimetre.
An extensive part of the course is dedicated to the wide range of GNSS applications existing today and prospects for the future. In addition to the traditional applications found in navigation and positioning, GNSS data contributes to weather forecasting, space weather monitoring, and geophysical investigations. Furthermore, GNSS is today fundamental for synchronization and distribution of time and frequency in e.g. communication networks.
