This reference and handbook describes theory algorithms and applications of the Global
Positioning System (GPS Glonass Galileo Compass). It is primarily based on source-code
descriptions of the KSGsoft program developed at the GFZ in Potsdam. The theory and algorithms
are extended and verified for a new development of a multi-functional GPS Galileo software.
Besides the concepts such as the unified GPS data processing method the diagonalisation
algorithm the adaptive Kalman filter the general ambiguity search criteria and the algebraic
solution of variation equation reported in the first edition the equivalence theorem of the
GPS algorithms the independent parameterisation method and the alternative solar radiation
model reported in the second edition the modernisation of the GNSS system the new development
of the theory and algorithms and research in broad applications are supplemented in this new
edition. Mathematically rigorous the book begins with the introduction the basics of
coordinate and time systems and satellite orbits as well as GPS observables and deals with
topics such as physical influences observation equations and their parameterisation
adjustment and filtering ambiguity resolution software development and data processing and
the determination of perturbed orbits.
