| Zusammenfassung |
| The EUMETSAT/ESA Metop/EPS GRAS radio occultation mission stands out for its
operational nature. From the beginning, EUMETSAT has decided to rely on an operational
system for provision of the auxiliary GPS products that are needed in the occultation
processing. This system is the GRAS Ground Support Network (GSN), operated in the
Navigation Facility of ESOC in Darmstadt, which was first presented at EGU in
2008.
The GRAS GSN is driven primarily by timeliness, availability and accuracy
requirements. The performance of the GSN, measured on a monthly basis, has not only
consistently met these requirements since the start of its operations, but has also been
improved through several system enhancements.
Currently, an additional service is being delivered on an experimental basis, consisting of
a near-real time Navigation Bit Stream product, which will allow the processing of open-loop
data, further increasing the scientific return of the GRAS instrument, or any other radio
occultation mission using this data.
This paper will present the GRAS GSN in its current configuration, and demonstrate its
excellent performance in terms of accuracy, availability and timeliness. The application
of the bit stream data will be shown. Some future evolution perspectives of the
GRAS GSN will also be addressed. It will be demonstrated that the GRAS GSN has
the potential of serving also other present and future radio occultation missions. |
