swipos-INFRA

swipos-INFRA enables the real-time integration of local monitoring networks into the homogeneous AGNES coordinate frame. The joint evaluation of the locally recorded measurement data and the measurements of the AGNES stations allows to verify the stability of local reference stations as well as to determine the displacements of object points.

swipos-INFRA is used for monitoring of slides, glaciers or the built environment. On the left you see the AGNES station Oberalp, on the right a visualization of visible GNSS satellites.
Using swipos-INFRA to embed AGNES stations in real-time calculations

Coverage

swipos-INFRA is available throughout Switzerland. For any given location, the average distance to the nearest AGNES station is approximately 30 km.

Equipment

To use swipos-INFRA, an internet connection is required for obtaining the AGNES data streams from the so-called NTRIP caster. Furthermore, a real-time capable geodetic evaluation software is required for the calculation of the network solution. Corresponding software packages are offered by almost all GNSS receiver manufacturers.

Alternatively, the data streams can be read in using a so-called NTRIP client and saved locally in RINEX format. These files can then be processed together with the data of the receivers on the object points in post-processing.

  • The achievable measurement accuracy depends on the hardware and software used, the measurement duration and the distance to the AGNES station used.
  • The measurement accuracy can vary in time, location and due to atmospheric influences.
