In 2018 we celebrated 25 years of development of radar altimetry, and the progress
achieved by this methodology in the fields of global and coastal oceanography, hydrology …

The need for precise orbit determination (POD) has grown significantly due to the increased
amount of space-based activities taking place at an accelerating pace. Accurate POD …

Since the early 1990s, high-precision multi-mission satellite altimetry has provided a 25-year-
long sea level record from which global mean sea level rise and superimposed interannual …

Abstract The International Laser Ranging Service (ILRS) was established by the
International Association of Geodesy (IAG) in 1998 to support programs in geodesy …

A new set of pelagic tide determinations is constructed from seafloor pressure
measurements obtained at 151 sites in the deep ocean. To maximize precision of estimated …

Abstract Comparison of satellite altimetry against a high‐quality network of tide gauges
suggests that sea‐surface heights from the TOPEX altimeter may be biased by±5 mm, in an …

One approach to reconstructing historical sea level from the relatively sparse tide-gauge
network is to employ Empirical Orthogonal Functions (EOFs) as interpolatory spatial basis …

One of the major uncertainty sources affecting Global Positioning System (GPS) satellite
orbits is the direct solar radiation pressure. In this paper a new model for the solar radiation …

The horizontal transport of water in Earth's surface layer, including sea level change,
deglaciation, and surface runoff, is a manifestation of many geophysical processes. These …

DORIS is one of the four space-geodetic techniques participating in the Global Geodetic
Observing System (GGOS), particularly to maintain and disseminate the Terrestrial …
