“…Nowadays, pure GPS had been replaced by the GNSS, currently based on several satellite constellations such as the American GPS, the Chinese BeiDou Navigation System, the Russian Global Navigation Satellite System (GLONASS), the Japanese Quasi-Zenith Satellite System (QZSS) and the European Galileo. Using the Real-time extended (RTX) technology, the Root Mean Square Error (RMSE) achieves a 2.9 cm accuracy [16].…”

The idea of cooperation has been introduced to selfdriving cars about a decade ago with the aim to reduce the occlusion caused by other users or the scene. More recently, the research efforts turned toward cooperative infrastructure bringing a new kind of the point of view as well as more processing power. This paper lies in this new field providing a survey that addresses the cooperative environment. We provide an overview of the architectures available to create such a system as well as the challenges introduced by the cooperation. Later, we review the main blocks involved in the perception: localization, object detection & tracking, map generation. Each block is reviewed under the prism of cooperation. We also provide a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis of the cooperative perception as well as a list of related scenarios alongside experimentations. Finally, we list some related datasets before concluding our paper, underlining the perspectives for further works.

“…The first study that included the relationship of PPP with GPS and initiated its development was conducted by Zumberge et al (1997). Afterwards, Yigit and Gurlek (2017) investigated the usability of PPP to detect the dynamic displacement response of a vertically vibrating structure, Ochałek et al (2018) assessed the accuracy of Trimble RTX with a Spectra Precision SP60 model GNSS receiver. Ilci (2020) tested the positioning performance and convergence time of Trimble-RTX technology, which is a real-time PPP service, evaluated the accuracy performance of the online GNSS post-processing service.…”

Today, new global positioning algorithms, techniques and technologies are emerging thanks to services such as International Global Navigation Satellite Systems (GNSS) Service (IGS) that offer orbit and clock correction data of satellite systems to all GNSS users. These solutions are developed in order to eliminate the disadvantages of current positioning techniques such as requiring more than one GNSS receiver and not exceeding a certain distance between the reference station and the rover. One of these innovative technology products is Trimble CenterPoint RTX Post-Processing (Trimble-RTX) technology. In this study, the point positioning performance of the Trimble-RTX service was investigated. The 31-day RINEX data obtained from 2 IGS stations are used in 4 different satellite combinations (GPS (G), GPS+GLONASS (G+R), GPS+GALILEO (G+E), GPS+GLONASS+GALILEO (G+R+E)) processed with Trimble-RTX. By comparing the obtained coordinates with the coordinates of the stations published by IGS, the accuracy and precision of the coordinates were evaluated for each satellite combination. As a result of the evaluation, it was seen that there were generally no significant differences between the results obtained from 4 different satellite combinations at the stations.

The main motivation of this study is to assess the accuracy performance of the real-time global GNSS PPP positioning service, i.e. Trimble CenterPoint RTX, and online PPP post-processing service, i.e. CSRS-PPP, in Çorum Province of Turkey. Within this scope, a geodetic point was established and GNSS data were logged in static mode at a measurement interval of 1 Hz. At the same time, the real-time coordinates of each measurement epoch were determined with the Trimble CenterPoint RTX positioning service using L-band geostationary satellite delivery. The collected GNSS data were also sent to the CSRS-PPP service and the coordinates of each measurement epoch were calculated. According to comparison of the coordinates obtained from CenterPoint RTX to the known coordinates, it was concluded that the 3D real-time positioning achieved at centimeter-level of accuracy within convergence time of a few minutes. On the other hand, CSRS-PPP also provided centimeter-level accurate positioning with post-processing mode. The overall results show that, the attainable accuracy with both approaches provided the requirements of the many scientific and practical surveying applications.
