The CGC continues to grow

Public GNSS data availability for the African continent has been a significant issue for sometime. Due to lack of a good communication infrastructure it is difficult to establish, operate and maintain permanent GNSS stations in our continent. (Yes as a person from the Canary Islands I consider myself geographically African as we have the mainland of the continent less than 100 Km away! politically and culturally we are Spanish, but the map is clear!!)

This short note is simply to inform everyone that the non-profit association I started in the Canary Island: “The Canary GNSS Center (CGC)” continues to uncover and publish publicly available GNSS data. We are mainly a mirroring service, centralizing the distributed African GNSS data into a single server to make life easier for everyone out there doing analysis.

At the CGC as a non-profit we face a significant problem of lack of resources, both time and money and severely limited as out members give what they can of their own efforts to the promotion of the association.payday loans Therefore the promotion of more GNSS data availability has been so far centered on:

1) Promoting GNSS as a simple, effective and inexpensive multidisciplinary technique for use across several disciplines

2) Promoting high-quality installations for the benefit of all. GNSS permanent installation can be very valuable for different research fields as long as proven methods are used and international guidelines followed.

3) Uncovering and publishing African GNSS data sources. It has become clear that the CGC cannot easily promote the installation of new GNSS stations so uncovering and making available existing stations is the next best thing!

Working following these ideas the CGC has promoted the wider publication of stations in Benin and Ethiopa (established with the help of the NGS), plus the permanent African stations of Fugro Seastar (with a 60 days data publishing delay), plus the permanent South African stations of Trignet, many of which aim to become IGS stations, and finally the new permanent Canary Island GNSS network promoted by GRAFCAN, which has so far made public 3 new stations in the Canary islands.

These are a few of the examples recently added to the CGC. You can follow the state of the African stations that the CGC is monitoring and storing through the CGC Information System:

Good positioning!!
