This open access volume contains the proceedings of the 5th Symposium on Terrestrial Gravimetry: Static and Mobile Measurements (TG-SMM2019) held in St. Petersburg, Russia, October 1 – 4, 2019. The symposium was hosted by the State Research Center of the Russian Federation Concern CSRI Elektropribor, JSC and was attended by 75 participants from 15 different countries. 32 oral and 20 poster contributions were presented in four different topical sessions: Terrestrial, shipboard and airborne gravimetry, Absolute gravimetry, Relative gravimetry, gravity networks and applications of gravimetry and Cold atom and superconducting gravimeters, gravitational experiments.

This volume includes a selection of papers presented at the IAG international symposium "Gravity, Geoid and Height Systems 2012" (GGHS2012), which was organized by IAG Commission 2 “Gravity Field” with the assistance of the International Gravity Field Service (IGFS) and GGOS Theme 1 “Unified Global Height System”. The book summarizes the latest results on gravimetry and gravity networks, global gravity field modeling and applications, future gravity field missions. It provides a detailed compilation on advances in precise local and regional high-resolution geoid modeling, the establishment and unification of vertical reference systems, contributions to gravity field and mass transport modeling as well as articles on the gravity field of planetary bodies.

This book series is composed of peer-reviewed proceedings of selected symposia organized by the International Association of Geodesy. It deals primarily with topics related to Geodesy Earth Sciences : terrestrial reference frame, Earth gravity field, Geodynamics and Earth rotation, Positioning and engineering applications.

These proceedings contain 27 papers, which are the peer-reviewed versions of presentations made at the International Association of Geodesy (IAG) symposium “Gravity, Geoid and Height Systems 2016” (GGHS2016). GGHS2016 was the first Joint international symposium organized by IAG Commission 2 “Gravity Field”, the International Gravity Field Service (IGFS) and the GGOS Focus Area “Unified Height System”. It took place in Thessaloniki, Greece, in September 19-23, 2016 at the premises of the Aristotle University of Thessaloniki. The symposium was organized by the Department of Geodesy and Surveying of the Aristotle University of Thessaloniki, which presently hosts the IGFS Central Bureau. The focus of the Symposium was on methods for observing, estimating and interpreting the Earth gravity field as well as its applications. GGHS2016 continued the long and successful history of IAG’s Commission 2 Symposia.

These proceedings contain a selection of peer-reviewed papers presented at the International Symposium on Geodesy for Earthquake and Natural Hazards (GENAH), Matsushima, Japan, 22-26 July, 2014. The scientific sessions focused on monitoring temporal and spatial changes in Earth's lithosphere and atmosphere using geodetic satellite systems, high rate GNSS as well as high resolution imaging (InSAR, Lidar). Researchers in various fields of geodesy discussed the role of geodesy in disaster mitigation and how groups with different techniques can collaborate toward such a goal.

Recognizing the increasing importance of the role of gravity and the geoid, and con sidering the substantial synergistic effects which result from close cooperation, the International Gravity Commission and the International Geoid Commission, both scientific bodies of the International Association of Geodesy, decided to hold a Joint Meeting under the common topic "Gravity and Geoid" in Graz, Austria, from Sept. 11 - 17, 1994. The earth's gravity field is increasingly attracting the attention of the geosciences for many reasons. As a response of the earth's internal mass distribution, it significantly helps us to understand the structure of the earth and its dynamics. On the other hand, the earth's gravity field controls the orbits of satellites and is of paramount im portance for accurate orbit prediction'. For geodesy the geoid, representing the gravity field, serves as a unique height reference surface. It is the link between satellite-derived positions and useful geodetic coordinates of utmost precision. For oceanography, the offset of the dynamic ocean surface from the geoid is the signal which bears important information about ocean circulation patterns.

This volume represents the proceedings of the International Symposium on Gravity, Geoid, and Space Missions (GGSM2004), held in Porto, Portugal, 30 August - 3 September 2004. The symposium encompassed the themes of Commission 2 (Gravity Field) of IAG, as well as interdisciplinary topics related to geoid and gravity field, including integration of heterogeneous data and contributions from satellite and airborne techniques. Special focus was on gravity-dedicated satellite missions like CHAMP, GRACE, and GOCE. Projects addressing topographic and ice field mapping using SAR, LIDAR, and laser altimetry, as well as missions and studies related to planetary geodesy were also covered.
