SG 2.1.1: Developments in near Earth gravity measurementson moving platforms

Chair: Derek van Westrum (USA)
Vice-Chair: Neda Darbeheshti (Australia)

Terms of Reference

Developments in gravity and gravity gradiometry measurements from (non-satellite) moving platforms continue at a rapid pace. Alongside conventional spring-based systems, sensors now include micro-electromechanical systems (MEMS), inertial measurement units (IMUs), and quantum absolute instruments. In addition to ships and fixed-wing aircraft, mobile platforms now include a wide range of drones (airborne, seaborne, and underwater). Proposals are even underway for optical clock deployments on moving platforms. SG 2.1.1 is focused on tracking all aspects of these developments: sensors, platforms, platform integration, analysis techniques, survey projects, and data applications.

Objectives
  • Communication between the gravity science community and the institutes, research groups, and companies that are developing novel instruments and deployments.
  • Coordination of scientific efforts and best practices regarding the collection and analysis of mobile platform gravity data.
  • Promotion and coordination of mobile gravity datasets for the establishment of regional gravity networks and other applications.
  • Organization of scientific workshops and meetings for the discussion of techniques and methods of mobile gravity measurements.
