“…Up to now, its GPS and Galileo signals generation capabilities and performances have been experienced and demonstrated, as in [3] and [4]. The simulator, which has a generation capacity of 16 different signals in the same time on the entire L band, has already been successfully tested with GPS L1 C/A, L1C, L5 and Galileo E1 and E5 receivers.…”

Evil Waveforms (EWF) threaten the integrity of GNSSs. Experienced once on GPS signals, such threats could also affect new GNSS signals, such as Galileo ones. NAVYS is a highly flexible GNSS constellation simulator capable of generating any existing navigation signal modulation. Moreover, it has been recently upgraded to be able to distort signals with ICAO EWF models, whatever the simulated constellation and/or modulation. The present paper hence demonstrates the effects of EWFs on Galileo signals, and compares it to the effects of the same anomalies on GPS signals. The distorted signals generated by NAVYS are first observed using classical signal measurement devices such as oscilloscopes and spectrum analyzers, and then with TAS own GNSS Environment Monitoring Station, GEMS.

With the multiplication of GNSS and the increasing complexity of the new GNSS applications, such as LocationBased Services applications, it will be essential in the coming years to have access to receivers test benches providing a series of test procedures being reproducible and standardized, enabling localization performance assessment. GNSS receiver test benches have to fulfill a twofold need: first, to provide a standardized methodology to enable comparison, in various controlled conditions, of different products that seem to have similar performance specifications on paper. And secondly, to provide a platform to test the functions of receivers in conditions closed to the real targeted environment.

“…On the other hand, the combined use of GNSSs could provide sufficient signals and therefore provide uninterrupted positioning service in the same environment. Moreover, more visible satellites from multiple GNSSs offer better satellite geometry for the positioning than single GNSS [ 8 ]. However, the different GNSS architectures may cause problems during system integration [ 9 , 10 ], so before integrating BDS with GPS, the differences between these systems must be studied.…”

The Chinese BeiDou navigation satellite system (BDS) aims to provide global positioning service by 2020. The combined use of BDS and Global Positioning System (GPS) is proposed to provide navigation service with more stringent requirements. Actual satellite data, signals and measurements were collected for more than one month to analyze the positioning service qualities from both BDS and GPS. In addition to the conversions of coordinate and timing system, five data quality analysis (DQA) methods, three signal quality analysis (SQA) methods, and four measurement quality analysis (MQA) methods are proposed in this paper to improve the integrated positioning performance of BDS and GPS. As shown in the experiment results, issues related to BDS and GPS are resolved by the above proposed quality analysis methods. Thus, the anomalies in satellite data, signals and measurements can be detected by following the suggested resolutions to enhance the positioning performance of the combined use of BDS and GPS in the Asia Pacific region.
