Global Navigation Satellite Systems Engineering, Policy, and Design
The International Astronautical Congress (IAC) consists of a scientific conference program and a space exhibition. Scheduled for October 1-5 in Bremen, a city straddling the Weser River in northwest Germany, it provides an opportunity for about 4,000 space actors from all over the world to come together.

Though the Senate approved next year’s funding for the Department of Defense (DOD) just before its Labor Day break there are still hurdles to overcome before the fiscal year runs out on September 30. For the most part further delay should not greatly impact GPS efforts — as long as stopgap funding is secured to keep DOD’s doors open — but extending the deadline will likely put the GPS IIIF program on hold.

Featuring multi constellation with L-Band and satellite-based augmentation system (SBAS), theF90 GNSS/RTK receiver from Geneq Inc., tracks GPS, GLONASS, Galileo and BeiDou and can maximize the tracking to observe all visible GNSS satellite signals, thereby providing maximum performance for accuracy and real-time measurements. F90 also supports L-Band function and can get centimeter accuracy with just one receiver, according to the company.
