Station Selection Criteria
Considerations:
1. Length of time series.
2. Quality of monument, assessed in a quantitative manner.
3. Number of jumps in time series, related to equipment changes.
4. Type of antenna being used (phase center corrections required)
5. Quality of station support and ability to influence owners of site
to maintain geodetic standards.
The committee felt that:
1. Detailed information was needed for every site, including photos
and descriptions of the monument and its location (e.g. bedrock).
2. Site operators should be invited to become a reference frame
site, but that no promise of inclusion would be made.
3. UNAVCO should maintain an online database on sites.
4. Initially, sites would need a minimum of 2.5 years with no
equipment changes to be included as a reference site.
5. Sites should be removed from the reference frame
if they no longer keep up to PBO standards.
