Understanding Satellite Navigation, 2nd edition explains the basic principles of satellite navigation technology with the bare minimum of mathematics and without complex equations. It helps you to conceptualize the underlying theory from first principles, building up your knowledge gradually using practical demonstrations and worked examples. A full range of MATLAB simulations is used to visualize concepts and solve problems, allowing you to see what happens to signals and systems with different configurations. Implementation and applications are discussed, along with some special topics such as Space Weather, Kalman Filter and Ionosphere.

New content in this edition:

• Compatibility and Interoperability of the systems (considering the current trend of combining all the individual systems for enhanced performance)
• Impairments like Jamming and Spoofing (considering the integrity requirements of GNSS as the systems are now used in various critical applications)
• Space Service Volume Applications (considering its utility towards futuristic usages)
• Space weather effect on GNSS (considering its effective influence in macro and mesoscale variation)

• How a satellite navigation system works
• How different independent systems can be combined to increase accuracy
• How to use MATLAB for simulation, helping to visualize concepts
• Current trends and implementation approaches for the technology, including the related impairments and ways to mitigate them
• The most recent services and applications of GNSS like PPP, Lunar PNT etc.
• How interplanetary space conditions affect the system
