Interference signals from privacy protection devices (PPDs) degrade global navigation satellite system (GNSS) performance and must be mitigated. This article presents practical results with the multi-parameter adaptive notch filter (MPANF) against a commercial-off-the-shelf (COTS) PPD. Additionally, the wavelet-based multi-parameter adaptive notch...
The precise location of forestry machines is of fundamental importance for sustainable, soil-conserving and equally efficient and safe timber utilization. However, with global navigation satellite system (GNSS) receivers available to date, reliable positioning in the sub-meter range and in real time in forest stands is not possible, as the environm...
An apparatus for obtaining a weighting matrix, the weighting matrix to be used to obtain one or more updated parameters affecting a time of response of a tracking loop; wherein the apparatus is configured to receive from a plurality of tracking loops respective loop dynamic estimates and/or loop noise estimates, weight each of the received loop dyn...
A receiver comprises an analog beamforming and nullsteering network connected to one or more antennas from receiving RF signals and configured to preprocess the RF signals in order to mitigate interferences within the RF signals; and a digital stage connected to the analog beamforming and nullsteering network and configured to further process the p...
Dear Readers,
I am pleased to announce the publication of the third edition (63(135)) of the Scientific Journals of the Maritime University of Szczecin in 2020. This edition contains the findings and opinions of the authors within thirteen articles, which are grouped into six fields: Civil Engineering and Transport, Environmental Engineer-ing, Mini...
Die Steuerung von Lichtsignalanlagen (LSA) hat einen wichtigen Einfluss auf die Qualität, die Sicherheit und die Umweltverträglichkeit des Verkehrsablaufs in städtischen Straßennetzen. Zu diesem Zweck kommen verschiedene Steuerungsansätze [1], [2] und Systeme zur Anwendung, die z.B. auch die Bevorrechtigung der Sondereinsatzfahrzeuge (SEF) von Poli...
This paper presents the GOOSE GNSS open receiver platform. The platform is based on a multi-frequency multi-constellation GNSS receiver which can be deployed either as a fixed PC receiver or as an embedded portable one. The main feature of this platform is to provide to GNSS software developers the possibility to have a deeper control on receiver h...
With the increase of navigation systems and their signals, advanced receiver architectures became the research focus. In current GNSS receivers, in general hardware based signal processing is utilized. At one hand this provides high performance and low power consumption but on the other hand limits the flexibility of the receiver. Since the flexibi...
For the typical user of positioning and navigation applications, a precise GNSS receiver is a black box which delivers not well specified raw measurements with very reduced configuration possibilities. However, the processing of precise positions from such measurements needs a deeper insight about the way how these measurements were obtained (filte...
This integrated circuit supports simultaneous reception and processing of the GPS L1/L5, Galileo E1/E5a, and GLONASS G1 signals with 40 tracking channels. The dual-band analog RF front-end is integrated on the same mixed-signal chip as the baseband hardware, including an embedded processor to close the tracking loops: overall, a compact, low-power,...
This paper describes the system architecture and implementation results of a robust and flexible dual-frequency 2×2 array processing GNSS receiver platform. A digital front-end FPGA pre-processes the incoming raw ADC data and implements interference mitigation methods in time and frequency domain. An optional second FPGA card can be used to realize...
This paper presents the overall architecture, the implementation, test setup, and first measurements results of a fully integrated multi-constellation two-frequency single-chip GNSS receiver. The ASIC supports the simultaneous reception and processing of the GPS L1/L5, Galileo E1/E5a and GLONASS G1 signals with 40 versatile tracking channels. The d...
In this paper, the implementation of a multi-constellation, multi-frequency automotive GNSS receiver is discussed. The main objective of this paper is threefold. First, to identify, in the context of automotive applications, the most promising GNSS signal combination and analyze its benefits and limitations. Second, to propose a receiver architectu...
The automotive sector requires ever higher availability, accuracy and reliability from the position solution. The demands of novel and innovative driver assistance systems can not be completely fulfilled, at an acceptable price, by current GNSS receivers. There is a need for a cost effective receiver so that driving assistance systems can be realis...
Several new requirements and challenges are introduced with the transition of traditional navigation applications towards location-based services (LBSs). This paper introduces the HIGAPS receiver concept. Aim of the HIGAPS project is to develop the concept for a combined Galileo/GPS receiver that is specially tailored for LBSs, E-911, and other con...
