The tracking performance of a global navigation satellite system (GNSS) receiver is altered by signal distortions of different kinds, ranging from transmitter and receiver imperfections to various forms of channel impairments. Accurate modeling of th

This paper presents the performance analysis of signals from the Galileo satellites in the E1 and E5a frequency bands and GPS L5 signals as measured by DLR’s experimental ground-based augmentation system. The results show that the raw noise and mul

Tracking Error Modeling in Presence of Satellite Imperfections

Autor: Matteo Sgammini, Felix Antreich, Christoph Enneking, Mariano Vergara, Yuji Zhu, Steffen Thoelert

Publikováno v: Navigation. 63:3-13

Modeling both nominal distortions and signal anomalies (i.e. Evil waveforms, ICAO threat models) is crucial for an accurate user error budget for SBAS and GBAS (multi- frequency, multi-constellation). Such analysis of particu- lar interest for the on

Two-dimensionally spread multicarrier CDMA ranging signals with PAPR lower than 3dB

Autor: Gonzalo Seco-Granados, Mariano Vergara, Felix Antreich

Publikováno v: ICL-GNSS

In this work we propose a methodology to design two-dimensional spreading codes for a multicarrier CDMA (code division multiple access) system with minimal multiple access interference (MAI) and minimal peak-to-average-power-ratio (PAPR). In particul

Spreading Code Design for a MC-CDMA Based GNSS Pilot Signal

Autor: Michael Meurer, Mariano Vergara, Felix Antreich, Gonzalo Seco-Granados

Multicarrier CDMA (MC-CDMA) can represent an alternative to classical DS-CDMA for the design of GNSS ranging signals. A first requirement MC-CDMA signals must fulfill is that their generation on a satellite payload be feasible. It is well known, inde
