That was then. This is now. When managed by a new ground control system, GPS III satellites will offer triple the accuracy and eight times the anti-jamming capabilities of the satellites currently...
BeiDou Signals, Future Receiver Design Highlighted at Stanford PNT Symposium By James D. Litton and Tom Langenstein James L. Litton The Stanford Center for Position, Navigation and Time conducted...
Autonomous GPS Positioning at High Earth Orbits To initially acquire the GPS signals, a receiver also would have to search quickly through the much larger range of possible Doppler shifts and code...
We appear incompletely before you this month. A funny thing happened on the way to the presses: we discovered that we had more content than pages in which to squeeze it. “All the news that fits to...
Not just supporting players, alternative positioning, navigation and timing (PNT) systems strengthen, augment and — when needed — replace GNSS. We explore how companies are using alternative PNT,...
By John Pottle and Neal Fedora John Pottle Precision matters. While “accuracy” is somewhat one-dimensional, “precision” is multi-faceted. We submit to you that whatever area of GNSS-based...
By Jenna R. Tong, Robert J. Watson, and Cathryn N. Mitchell, University of Bath Using signal-to-noise measurements from a single commercial-grade L1 GPS receiver, it is possible to detect...
