Dataset on national CORS networks

Two national CORS networks have been established in Slovenia, i.e.:

- the SIGNAL Network (the abbreviation means: SlovenIa-Geodesy-NAvigation-Location) and

- the Zero-Order Combined Geodetic Network.

The SIGNAL Network provides data and services for the positioning in the national coordinate and height reference systems (CRS, HRS). The Zero-Order Combined Geodetic Network enables quality control of the SIGNAL Network data and services as well as the realization of the national spatial reference system (SRS) and monitoring of its quality in long term.

The data provided by the national CORS networks contain GNSS observations at the permanent GNSS stations and their corrections generated by processing the data from the whole network. These data are needed for the positioning in the national CRS/HRS by applying:

- kinematic GNSS positioning in real time (RTK) or

- static or fast static GNSS positioning with processing of the collected observations in the office (post-processing).

The data for the real-time positioning are available in the RTCM format via web connection (NTRIP protocol) or via dial-up acces (GSM) as:

- RTK services for the positioning based on phase observations ( few cm accuracy) and

- DGPS services for the positioning based on code observations (few dm accuracy).

The GNSS observations collected for the post-processing are available in RINEX (Receiver Independent Exchange) format as:

- RINEX files for the CORS network stations or

- virtual RINEX files for the selected location.

RINEX data can be accessed via the RINEX Portal of the Service for the GNSS. They can be ordered for a set of CORS network stations or selected locations of GNSS surveys, for the required time span and interval of registration of the GNSS signals.

Statement

The accuracy of the obtained coordinate points depends on the quality of the GNSS receiver, as well as on the measurement method:

* a few decimeters up to one meter is achieved within the DGPS method using a single-frequency receiver

* a few centimeters are achieved within the RTK or kinematic method using the dual frequency (geodetic) receiver

* the accuracy of 1 cm is achieved within the static or fast static method using the dual frequency (geodetic) receiver.

The database is managed in the national ETRS coordinate system D96/TM.

Data are achived from 16 GNSS stations + shared GNSS stations from the neighboring countries ( network processing of data station continuously cover entire territory within the perimeter formed by external stations).
