Global Navigation Satellite Systems Engineering, Policy, and Design
This summer, French railway company SNCF performed successful tests of an autonomous train, using Galileo-enabled receivers. The vehicle ran a distance of four kilometers with the help of remote control. SNCF intends to develop its own prototypes of autonomous freight and passenger trains by 2023.

To gauge the present state of mind of the GNSS and PNT community, the state of play in application development, and the state of the art in positioning, navigation and timing technology, we asked four international experts for their perspectives. Here are the questions posed to them.

Very occasionally, history repeats itself, in oddly nuanced ways. I stand today at such a juncture. Nineteen years ago Glen Gibbons, the founder of this magazine, hired me as his lieutenant for another satnav publication—for which he was also the founding editor.

The complex and mission-critical needs of the autonomous vehicle market demand innovation at higher levels in several different sensors and in sensor integration. A new photonic chip technology offers promise in providing high-volume, low-cost manufacture of high-end, tactical-grade performance fiber-optic gyros (FOGs)for inertial navigation in GNSS-obstructed environments.
