Remedy 1: Comparison of at least two geodetic software packages

Primary gap remedy type: 
Research
Relevance: 

The proposed remedy will help to better define GRUAN GNSS-IPW uncertainties, starting from the level reached thus far, with data processing and uncertainty estimation.

Measurable outcome of success: 

The first outcome will be making GRUAN GNSS-PW with transparent uncertainty analysis usable for the ‘Virtual Observatory’. It  should also help to make decisions for selecting and extending the ‘Virtual Observatory’ database with verified and usable non-GRUAN GNSS-data available worldwide (potentially processed with different geodetic software sand data processing strategies compared to GFZ). In the future there could be a relatively dense global dataset for GNSS-PW data usable for the ‘Virtual Observatory’.

Expected viability for the outcome of success: 
  • High
Scale of work: 
  • Consortium
  • Programmatic multi-year, multi-institution activity
Time bound to remedy: 
  • Less than 3 years
Indicative cost estimate (investment): 
  • Low cost (< 1 million)
Indicative cost estimate (exploitation): 
  • No
Potential actors: 
  • EU H2020 funding
  • Copernicus funding
