TL;DR: In this article, the entire field of satellite geodesy (status spring/\break summer 2002) is covered, including reference systems, time, signal propagation, and satellite orbits.
Abstract: Completely revised and updated edition. The book covers the entire field of satellite geodesy (status spring/\break summer 2002). Basic chapters on reference systems, time, signal propagation, and satellite orbits are updated. All currently important observation methods are included and also all newly launched satellites of interest to geodesy. Particular emphasis is given to the current status of the Global Positioning System (GPS), which covers now about one third of the book. A new chapter on Differential GPS and active GPS reference networks is included. The GPS modernization plans, GLONASS, the forthcoming European system GALILEO, modern developments in GPS data analysis, error modelling, precise real time methods and ambiguity resolution are dealt with in detail. New satellite laser ranging missions, new altimetry missions (e.g. TOPEX/Poseidon, ERS-1/2, GFO, JASON), and new and forthcoming gravity field missions (CHAMP, GRACE, GOCE) are also considered. The book serves as a textbook for advanced undergraduate and graduate students, as well as a reference for professionals and scientists in the field of engineering and geosciences such as geodesy, surveying, geo-information, navigation, geophysics and oceanography.

TL;DR: In this paper, a brief history of navigation is given, highlighting the needs that led ultimately to the development of 3D satellite based navigation, and the use of bandwidth compression to overcome the SNR problem is discussed.
Abstract: A brief history of navigation is given, highlighting the needs that led ultimately to the development of 3-D satellite based navigation. The evolution of Navstar, commonly known as GPS (Global Positioning System), is traced from its initial conception in 1960. The use of bandwidth compression to overcome the SNR problem is discussed. An explanation of how the GPS works is provided. Civilian as well as military applications are examined. >

TL;DR: The offset carrier modulations and their characteristics are described, showing that they provide many advantages for Modernization.
Abstract: An integral aspect of GPS Modernization is transmission
of a new military signal in the current frequency bands
around L1 and L2 in addition to the currently used P(Y)
code and C/A code signals. There are considerable
advantages to a new military signal whose spectrum is
distinct from those of the current signals. This paper
describes the offset carrier modulations and their
characteristics, showing that they provide many
advantages for Modernization. The parametric families of
linear and binary offset carrier modulations are defined.
Various modulation properties are presented and compared
for representative binary offset carrier modulation designs
relevant to GPS Modernization.
