Global Navigation Satellite Systems Engineering, Policy, and Design
Congress is in the midst of a confusing multi-budget-year scramble to fund the government for fiscal year 2018 – which is now nearly half over – while taking into account additional monies made available in a budget deal signed February 9 and keeping an eye on the deficit ballooning from that deal and under the FY19 White House budget submitted February 12.

This free workshop will share information about QZSS and GPS related technologies and the latest developments in the applications of this technology in a range of sectors including agriculture, autonomous driving, advanced route guidance and the maritime sector. The all-day workshop will explore avenues for future cooperation with Australian organizations, both in the private and public sectors and report on trials undertaken in Australia using QZSS applications.

The opening of the New Year at the European Space Agency (ESA) came in the wake of another spectacular launch for Europe’s GNSS program; last December, four Galileo satellites were lifted into space from Kourou, French Guyana, on board the thundering Ariane 5 launcher, by all accounts leaving witnesses awestruck.

A decision by the Department of Defense (DoD) may be what’s holding up action on the Air Force’s $10 billion plan to build 22 new GPS IIIF satellites and could increase the chances of further, perhaps substantial, delays.

All applications of satellite navigation show a strong growth. They can now rely on four global systems (GPS, GLONASS, Galileo and BeiDou) and additional regional systems, sometimes aiming for future global extension (QZSS, NavIC). All these systems and their applications rely on very limited satellite orbit spectrum. This article is providing background and insights on the growing pressure on this limited resource, giving rise to proposals for “sharing” spectrum. How satellite navigation will survive and find the necessary spectrum resources to grow is reviewed in details in the following paragraphs.
