Global Navigation Satellite Systems Engineering, Policy, and Design
One of the more popular sessions in recent years at the annual ION GNSS+ technical meeting is the panel discussion on a variety of satellite-based navigation systems, and it appears as if Chinese officials will have plenty of updates on its BeiDou navigation and positioning system to share.

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.

The deck of a tall ship rolled heavily beneath me as a freshening wind whistled through the rigging. A sextant in one hand and a stop watch in the other, I carefully listened. “Tock, Tock, Tock, Tock… the time is now fourteen hours, fifty-eight minutes, Coordinated Universal Time… Dong.” I clicked the stop watch in preparation for checking and winding the ship’s chronometers and measuring the height of the sun at local apparent noon.
