This book provides a sound theoretical basis for the the different gravity field recovery methods and the numerics of satellite-to-satellite tracking data. It represents lectures given at the ‘Wilhelm and Else Heraeus Autumn School’ in Bad Honnef, Germany, October 4-9, 2015. The emphasis of the school was on providing a sound theoretical basis for the different gravity field recovery methods and the numerics of data analysis. The approaches covered here are the variational equations (classical approach), the acceleration approach and the energy balance approach, all of which are used for global gravity field recovery on the basis of satellite observations. The theory of parameter estimation in satellite gravimetry and concepts for orbit determination are also included. The book guides readers through a broad range of topics in satellite gravimetry, supplemented by the necessary theoretical background and numerical examples. While it provides a comprehensive overview for those readers who are already familiar with satellite gravity data processing, it also offers an essential reference guide for graduate and undergraduate students interested in this field.
This paper treats the RMS-errors associated with the position and velocity of a satellite or spacecraft when tracked by all types of present day tracking systems. These errors are based on uncertainties in measurements made with the systems as well as those associated with their location. The present paper (Part I) is principally a theoretical treatment which establishes the mathematical models necessary to solve for the errors in satellite position and velocity. It is presumed throughout the paper that these errors are to be determined for discrete points in the satellite's orbit. This approach enables one to calculate the error propagation during short time intervals (order of seconds). This is of particular interest for instance for evaluation of a guidance system during a short burning phase. A least square solution of non-simultaneous observations would diverge (matrices involved become ill-conditioned). This condition imposes a constraint on the method of solution which is, that either one tracking system can measure both position and/or velocity, or that several tracking systems observe the satellite simultaneously to produce the equivalent effect. Both these alternatives are considered in Part I.

This project was concerned with three related questions of an optimal design of a climate observing system: 1. The spatial sampling characteristics required from an ARGO system. 2. The degree to which surface observations from ARGO can be used to calibrate and test satellite remote sensing observations of sea surface salinity (SSS) as it is anticipated now. 3. The more general design of an climate observing system as it is required in the near future for CLIVAR in the Atlantic. An important question in implementing an observing system is that of the sampling density required to observe climate-related variations in the ocean. For that purpose this project was concerned with the sampling requirements for the ARGO float system, but investigated also other elements of a climate observing system. As part of this project we studied the horizontal and vertical sampling characteristics of a global ARGO system which is required to make it fully complementary to altimeter data with the goal to capture climate related variations on large spatial scales (less thanAttachment: 1000 km). We addressed this question in the framework of a numerical model study in the North Atlantic with an 1/6 horizontal resolution. The advantage of a numerical design study is the knowledge of the full model state. Sampled by a synthetic float array, model results will therefore allow to test and improve existing deployment strategies with the goal to make the system as optimal and cost-efficient as possible.
