The African Geodetic Reference Frame (AFREF) was conceived as a unified geodetic reference frame for Africa to be the fundamental basis for the national and regional three-dimensional reference networks fully consistent and homogeneous with the International Terrestrial Reference Frame (ITRF). To achieve this, Continuously Operating Reference Operating Stations (CORS) or Global Navigation Satellite System (GNSS) base stations requires to be established.

RCMN is such a base station hosted by RCMRD, Nairobi. It is Leica 1200 GG receiver and is being managed by spider CORS software. The station is also International GNSS services registered. For more information check AFREF website and AFREF data center for CORS stations in Africa and data holding.

RCMRD also publishes quarterly AFREF newsletter on status and the implementation and other GNSS news and related technologies. Click here for AFREF newsletters and other AFREF documents.

RCMN participates in IGS Real Time Pilot Project (RTPP), (RTCM messages 3.0;1004(1),1006(15),1008(15),1012(1))are available using NTRIP on the IGS caster. A username and password are not required to access the stream; however a password is required to access the IGS NTRIP caster and is available via online registration at IGS caster.

RTK & DGPS Streaming RTK observables (RTCM Messages 3.1X ver .3.1) are available using NTRIP at IP address 197.248.78.24:2101. A username and password is required to access our stream which you can acquire through RTK Registration. Please signup and fill in your credential for registration. RTK surveys can now be carried within 30km radius from RCMN with RCMN as the base.

Continuously Operating Reference Station (CORS) 

A Continuously Operating Reference Station (CORS) network is a network of RTK base stations that broadcast corrections, usually over an Internet connection. The CORS network is a multi-purpose, multi-agency cooperative endeavor, combining the efforts of hundreds of government, academic, and private organizations. Most applications of Global Positioning System (GPS) technology in surveying, mapping, and related disciplines have accuracy requirements that necessitate the use of a relative positioning technique. Many organizations are establishing GPS continuously operating reference stations (CORS) in support of these activities. CORS facilities collect and record, in an automated manner, the GPS data at a known location that are required for relative positioning.  Some of the CORS station available in our region are accessible on this link https://cors.rcmrd.org/
