  • NEO Project Group

    Near Earth Objects are a substantial hazard to our civilization, but also an opportunity for further space development. The NEO group focuses on everything from detection and mitigation to resource utilization. Check out our page for more information and learn how to get involved!

  • SLP Project Group

    The Space Law and Policy Group incorporates all aspects of those two broad fields of study. It develops the term ‘space law’ as all types of space-related international and national regulations and laws, whereas it interprets the term ‘space policy’ as all kinds of objectives and action plans of the international space community.

What is GNSS?


GNSS stands for Global Navigation Satellite Systems. Currently the United States operates only fully operational GNSS - Global Positioning System (GPS), with a constellation of at least 24 navigation satellites operational at all times. The Russian GLONASS system follows closely in operation, while the Chinese and Europeans are currently developing their own systems, Beidou/Compass and Galileo, respectively. Other countries, such as India and Japan, have regional augmentation systems to support greater positioning, navigation, and timing of the GPS systems in their relative regions. With the increasing number of GNSS systems and ever increasing use of GNSS applications, there is a strong need to have all systems work together for interoperability and compatibility to ensure the safety of users.
