Vector Delay Lock Loops

GNSS receivers determine their position and clock bias by measuring the arrival times of satellite signals. Delay lock loops (DLLs) are used in traditional receivers to measure the arrival times of the signals.

GPS Civil Funding

The Federal Aviation Administration (FAA) has told those awaiting their slice of the GPS civil program budget that the funds are on the way.

The money, which is supposed to support that portion of the GPS program springing from the needs of civilian users, has been held up for months. In fact, as of late August — with less than 40 days left to go in the fiscal year — the money had not been transferred to either the military’s GPS Directorate or the National Coordination Office (NCO) for Space-Based Positioning, Navigation, and Timing (PNT).

Improving GNSS Attitude Determination

This article describes an integration of a single-frequency GNSS, two-antenna heading system with low-cost inertial and magnetic field sensors in order to improve the availability and reliability of pure GNSS attitude determination. This method calculates a redundant attitude solution in an error-state Kalman filter using different sensor setups. As a result, the process of carrier phase ambiguity resolution accelerates.

Spoofs, Proofs & Jamming

TABLE 1. Spoofer antenna requirements for various hardened GPS signal types

“Here is Edward Bear, coming downstairs now, bump, bump, bump, on the back of his head, behind Christopher Robin. It is, as far as he knows, the only way of coming downstairs, but sometimes he feels that there really is another way, if only he could stop bumping for a moment and think of it. And then he feels that perhaps there isn’t.”
– A.A. Milne, Winnie-the-Pooh

Is our faith in the integrity and infallibility of the Global Positioning System misplaced or, perhaps, insufficiently grounded?
