This paper presents the design of a satellite navigation receiver architecture tailored for
future Lunar exploration missions, demonstrating the feasibility of using Global Navigation …

The extreme weakness of a global navigation satellite system (GNSS) signal makes it
vulnerable to a wide variety of interfering signals, falling within the GNSS frequency bands …

This paper describes and demonstrates an assisted GPS technique, termed “Collective
Detection,” for combining satellite correlograms to enable rapid acquisition and direct …

This work addresses the signal acquisition problem using an array of antennas in the
general framework of Global Navigation Satellite Systems (GNSS) receivers. We propose a …

The new signals employed by modern global navigation satellite system (GNSS) will be
characterized by a data/pilot structure and by the presence of secondary codes. These …

In this paper, a new, noncoherent architecture for global navigation satellite system tracking
loops is proposed and analyzed. A noncoherent phase discriminator, able to extend the …

The GPS L1 signal is being augmented by L1C and the European GNSS Galileo is under
development. The GPS L1C and Galileo L1 signals use a common design and in particular …
