Number of stations:
325 stations distributed in the regions of the Kingdom of Saudi Arabia.
It is divided into two types:
The maximum distance between stations = 146 km.
The minimum distance between stations = 25 km.
Average distance between stations = 77 km.
The goal of the network:
- Construction and maintenance of the geodetic reference frame for the Kingdom of Saudi Arabia, KSAREF.
- Real-time service to improve position accuracy to centimeter and decimeter level.
- Provide raw observations and data after performing calculations and processing on the network stations.
- This network serves scientific and research centers interested in the study of Earth sciences.
- Reducing cost, effort and time when surveying, and positioning using GNSS.
- Satellite positioning data:
- RINEX positioning data:
The KSA-CORS provides easy access for users to RINEX format GPS data to perform desktop processing of their GPS data in order to obtain more accurate results. Currently, we provide users participating in the network the means of obtaining data in the formats RINEX 2.11, RINEX 2.10 and RINEX 3.02 from Through the network's website (https://ksacors.gcs.gov.sa).
- GPS data in Trimble Format:
The KSA-CORS provides easy access for users to Trimble Format GPS data in order to perform desktop processing of their GPS data in order to obtain more accurate results. Currently, we provide users participating in the network with means of obtaining data in T02, T01 and DAT formats through a site Network (https://ksacors.gcs.gov.sa)
- Provide virtual RINEX files:
Virtual RINEX files are a common product for satellite positioning applications. It is also very useful when the baseline length between the reference station and the unknown location is large. Users participating in the network can create a virtual reference station by choosing a location and the special processing engine will The network creates a virtual station for that site and creates a virtual file in RINEX format that can be used as a reference station in the processing process. The default RINEX file can be defined as a file that includes positioning data for an imaginary reference station not actually used (default) whose location was chosen by the user. To get a default RINEX file, you can enter Cartesian coordinates or geographical coordinates. You can also choose the location directly from the map of the site of interest.
Currently, we offer network subscribers the means to obtain virtual RINEX files through the network's website (https://ksacors.gcs.gov.sa)
- KSACORS Site Logs
The site records for the network stations include historical information for each station regarding changes made to the devices used in each station (receiver / antenna), it also includes an approximate location of the station and data on the owner, the method of construction, and others. The Network Administration also notes that the coordinates / locations included in the site records and the GPS files in RINEX format are approximate, not accurate, coordinates.
