GOP's Trop-NET system for near real-time troposphere monitoring

GPS meteorology, i.e. routine near real-time ground-based GPS troposphere monitoring, has been well established in Europe during past decades. New challenges, however, occur such as improving temporal and spacial resolutions, monitoring assymetry with use of data from multi-GNSS satellites, more fast estimation and others. Since 1999, GOP has played a key role in establishing of GNSS-meteorology in Europe as well as in developing and introducing precise global GNSS products and advanced tropospheric products. Natuarlly, the origin of the Trop-NET system for NRT tropospheric production based on Bernese GNSS software (BSW) thus comes from the GOP developments of routine GNSS data processing and related servicesin support of scientific applications:

The Trop-NET package consists of the source code on top of the BSW Bernese Processing Engine, several independent modules and specific processing strategy. These should sopport: a) faciliting an establishment of new analysis centre, b) improving the tropospheric NRT product coverage in Europe (GNSS4SWEC) or worldwide (EGVAP), c) improving the homogeneity of NRT tropospheric estimates (commonly agreed strategy, synchronized updates etc) and, finally d) giving a possibility to share future developments of various modules.
