Session 2: Site Surveys
Friday - October 24
Session 3: Analysis and SINEX
| chair: P. Sarti, co-chair: D. Angermann | ||
| 09:00 - 11:00 | The session aims are the following This session will focus on the procedures used for estimating the eccentricity vectors between different co-located space geodesy techniques using terrestrial data. The problems that relate to the definition of immaterialized Reference Points using terrestrial observations will be addressed: the different softwares used for data processing along with the geometrical constraints that have been applied within the softwares will be discussed. The tight connection between the estimation model and the surveying procedure will be highlighted. The generation of SINEX files from terrestrial data will be discussed: it is the final step of an efficient and complete local survey. | |

Session 4: Reporting
| chair: A. Nothnagel, co-chair: B. Richter | |
| 11:30 - 12:30 | The first part of Session 4 is concerned with the survey reporting document, the report content, the level of detail, the organization and the format. Alex Nothnagel, John Dawson, Michel Valerie, and Wolfgang Schlueter will present examples of survey reports already produced. A strawman report template for the standard report will be presented for discussion. In this part of Session 4, we will try to come to closure on a standardized report content and structure. If we cannot come to closure, we will identify the issues of disagreement and a path toward resolution. Presentations of Example of survey reports J.
