For driverless vehicles, current GNSS meter-level positioning accuracy still serves for lane-level detection. But hazardous misleading information poses a serious, disruptive and critical safety concern.
By Inside GNSSAn innovative positioning engine based on a safety-oriented paradigm uses a dual-frequency GNSS receiver, automotive cameras, accurate maps, low-cost inertial sensors and vehicle odometry. The real-time integrity layer bounds the error of each estimated value with a confidence level for safe navigation.
By Inside GNSSThis 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.

By Peter GutierrezTo 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.
By Inside GNSSVery 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.
By Alan CameronThe Defense Department urged spectrum regulators this week to reject a proposal by Virginia-based Ligado Networks to build a wireless terrestrial communication system that could, it said, interfere with GPS.
