Space Weather is the variation in Sun energy emissions, solar wind, magnetosphere, ionosphere and thermosphere, which can influence the performance and reliability of a variety of space borne and ground-based technological systems. As such Space Weather is recognised as the cause of significant errors experienced by Global Satellite Navigation Systems (GNSS), Satellite Based Augmentation Systems (SBAS) and their users.

GNSS or SBAS signals, propagating from a satellite to the user receiver, pass through the ionosphere where they are subject to the damaging effects of Space Weather. Under these conditions pseudorange errors and signals scintillations at user receiver level are present. The effects are critical at low latitudes where most of the developing countries are located.

The purpose of the proposed workshop is to give theoretical and practical training on the physics of Space Weather and its main effects on the GNSS operations with particular emphasis on the low latitudes ionospheric processes related to Space Weather.

This workshop is the number 10 of the series of activities in the field carried out since 2009 by the ICTP T/ICT4D in partnership with the Institute for Scientific Research (ISR) of Boston College done with the collaboration of the International Committee on GNSS of the UN Office of Outer Space Affairs and The Institute of Navigation both in Trieste and in Africa.
During the first day of the Workshop a review of the impact of these training efforts on the capacity building in the field in Africa and in general in developing countries will be given.

  • Impact of the ICTP T/ICT4D Boston College ISR joint training activities on GNSS science and applications in developing countries. (Speakers from Nigeria, Cote d’Ivoire, Ethiopia, Argentina and Malaysia will describe research and academic achievements in their countries as a result of the joint training activities)
  • Introduction to satellite navigation and positioning (Representatives of national and international institutions dealing with GNSS activities will be invited to illustrate the importance of satellite navigation for the developing countries)
  • GNSS: systems and operations
  • Introduction to Space Weather
  • Continuous and transient transport of energy from the Sun to the Earth 
  • Ionosphere and its response to Space Weather with particular attention to low latitudes
  • Space Weather effects on GNSS operations
  • Computer Laboratory exercises on the use of Space Weather data for GNSS research and applications

The deadline for submitting applications expired on 1 February 2018.
