ISWI Newsletter - Vol.3 No.35
31 March 2011

Dear ISWI Participant:

The following note was received by myself from Dr Hans Haubold of the UNOOSA in Vienna, Austria. You can access the attached pdf by clicking the indicated link inside of this email message. This link is alive for only a few weeks. But all "ISWI Newsletters" are archived at the ISWI website (this site) for easy access.

Dear George,

Among the IHY/ISWI instrument arrays, we have GPS-Africa, SCINDA, and CIDR which are doing very important research work with the GPS signal for monitoring solar activity impacts on the ionosphere. Other IHY/ISWI instrument arrays, among them MAGDAS, are utilizing GPS for pnt (positioning, navigation, timing). Having said this we know that Global Navigation Satellite Systems (GNSS) are themselves exposed to adverse impacts of solar activity.

The attached report of the Royal Academy of Engineering (London, UK), titled Global Navigation Space Systems: reliance and vulnerabilities, refers in detail to GNSS and space weather and this report might be of interest to readers of the ISWI Newsletter.

We also note with appreciation that the Committee on Global Navigation Satellite Systems (ICG) co-organizes and co-sponsors the ISWI workshops 2010-2012.

Thank you, Hans
