Evaluation of BDS-2 real-time orbit and clock corrections from four IGS analysis centers

The real-time ionospheric data streams are continuously being provided by a number of International GNSS service analysis centers such as Centre National d’Etudes Spatiales (CNES), Chinese Academy of Sciences (CAS), Universitat Politècnica de Catalunya (UPC), and Wuhan University, however, the performance evaluation of these Real-Time Global Ionosphere Map (RT-GIM) products is essential. We assess the quality and consistency of these RT-GIM products from the declining phase of solar cycle 24 (year 2017) to the maximum of solar cycle 25 (year 2024) by comparing with Final GIMs provided by Center for Orbit Determination in Europe (CODE) and Jason-3 altimetry satellite. The results suggest that during the low solar activity periods (2017–2022), all the RT-GIMs perform almost similar. However, the performance of the CNES and CAS RT-GIMs strongly deteriorates as the solar cycle proceeds towards the maximum (2022–2024) with annual RMS values remains between 9 and 7.5 TECU. The external validation vs Jason-3 during this maximum period suggested that the accuracy of the UPC RTGIMs is nearly identical to the final CODE GIMs at typically 4–10 TECU in standard deviation over oceans, while performance degradations are recorded for rest of the RTGIMs exhibiting high standard deviations. Results suggest that the high RMS errors in GIMs from CNES and CAS might be related to the geomagnetic inclination misalignments followed by the map projections as both maps form single peak along geomagnetic equator during high solar activities. In addition, under the presence of a severe G4-class geomagnetic storm, CNES RT-GIMs undergoes severe accuracy degradation across all continents recording a − 20 to − 40 TECU bias offset. Meanwhile, UPC RT-GIM remain the most consistent and stable performer (both, globally and over oceans) that provides accurate global ionospheric information which is promising for their applications in real-time precise GNSS positioning.

Between 1984 and 1986, 888 final-year medical students from The Universities of Sydney, Western Australia and Newcastle took part in trial examinations that comprised multiple-choice questions, modified essay questions and a patient management problem. Differences in student performance among the schools were small. In 1984 and 1985, Newcastle students performed less well than did Sydney students on multiple-choice questions that were prepared by The University of Sydney, but there was no difference between the schools in 1986. Sydney students performed better than did Newcastle students on the multiple-choice question paper that was prepared by The University of New South Wales in 1984, but in the last two years no differences have been detected between the schools in performance on this paper. The performance on modified essay questions in 1984 suggested that Newcastle students were stronger in behavioural sciences and weaker in pathological sciences than were Sydney students. Sydney students performed less well than did Newcastle students in the patient management problem in 1985, particularly in the area of the use of clinical investigations. On the one occasion of testing that involved students from The University of Western Australia (in 1985), these students performed best of the three schools in the patient management problem, and roughly equally with students from Sydney and Newcastle in the multiple-choice question papers. Differences among the schools usually amounted to less than 10% and might have been accounted for by differences in familiarity with test instruments. We conclude that medical students are likely to graduate from The University of Sydney, Western Australia and Newcastle with similar levels of knowledge of internal medicine. Possible differences in problem-solving ability require further study, particularly in the clinical setting.

This thesis explores the intersections of ubiquitous technologies, embedded democracies,
\nand bright green futures and how that is resolved in a user interface design for a citizen centric
\nmobile phone application.
\nMy main question of enquiry is: How can I connect citizens to their local environment through
\nhuman interface design on a mobile platform? The Politics of Nature by Bruno Latour
\nproposes;
\n‘An end to the old dichotomy between nature and society... of a collective, a
\ncommunity incorporating humans and non humans and building on the
\nexperiences of the sciences as they are actually practiced.’ (Latour, 2004, p.
\n186-206).
\nDesign research throughout this thesis explores the intersections of urban health, human
\ninterface design, captology, mobile and sensor technology and citizen science while proposing
\nan interactive mobile application for local and national governments to engage with an
\nincreasingly urban and technological savvy agora.
\nThe aim of the accompanying mobile application prototype titled Tune In, Share Out (TISO),
\ngives access to air and water quality information coupled with a mobile air quality sensor
\ndevice which enables urban citizens to directly participate in the concept of the quantified self
\n(Fawkes, 2010) by monitoring their pollution paths, while sharing this information through their
\nrespective social networks within a mobile mapping platform.
\nConcurrently this project contributes air quality information to aid citizens, scientists and city
\nplanners to make more informed and sustainable decisions within their local environment and
\nagora.
\nBenefits of this application include citizen and environmental interaction and awareness, the
\nability for local government and citizens to enhance their tacit and embodied knowledge of
\nrespective groups and individual’s, enabling greater understanding of each others perspective,
\nwhile offering a channel of participation to an otherwise silent segment of society.

The Global Space-based Inter-Calibration System (GSICS) is a new international program to assure the comparability of satellite measurements taken at different times and locations by different instruments operated by different satellite agencies. Sponsored by the World Meteorological Organization and the Coordination Group for Meteorological Satellites, GSICS will intercalibrate the instruments of the international constellation of operational low-earth-orbiting (LEO) and geostationary earth-orbiting (GEO) environmental satellites and tie these to common reference standards. The intercomparability of the observations will result in more accurate measurements for assimilation in numerical weather prediction models, construction of more reliable climate data records, and progress toward achieving the societal goals of the Global Earth Observation System of Systems. GSICS includes globally coordinated activities for prelaunch instrument characterization, onboard routine calibration, sensor intercomparison of near-simultaneous observations of individual scenes or overlapping time series, vicarious calibration using Earth-based or celestial references, and field campaigns. An initial strategy uses high-accuracy satellite instruments, such as the NASA Moderate Resolution Imaging Spectroradiometer (MODIS) and Atmospheric Infrared Sounder (AIRS) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT)'s Centre National d'Études Spatiales (CNES) Infrared Atmospheric Sounding Interferometer (IASI), as space-based reference standards for intercalibrating the operational satellite sensors. Examples of initial intercalibration results and future plans are presented. Agencies participating in the program include the Centre National d'Études Spatiales, China Meteorological Administration, EUMETSAT, Japan Meteorological Agency, Korea Meteorological Administration, NASA, National Institute of Standards and Technology, and NOAA.

The temporal and spatial evolution of dispersed media is a fundamental problem in a wide range of physicochemical systems, such as emulsions, suspensions and aerosols. These systems are multiphasic and involve compounds of different densities. They are therefore subject to the influence of gravity which determines the sedimentation rate of their dispersed phase. This effect can be dominant and prevent a detailed study of the phenomena occurring between the constituents themselves, such as the coalescence of drops in emulsions, the evaporation of droplets or the flocculation in suspensions. In this context, the Centre National d’Etudes Spatiales (CNES) has recently supported the development of a new instrument to produce populations of droplets, a few micrometers in radius, under controlled conditions with the objective of allowing a detailed study of their properties in microgravity conditions. The principle of this instrument is to generate, by a fast compression/expansion of air, populations of water droplets and to track their evolution by optical scanning tomography in transmission mode within a volume of approximately 2 mm 3 . Parabolic flight experiments have shown the possibility to generate and accurately follow the evolution of populations of several hundred droplets for more than 20 s. The first experimental results show that it is possible to study their evaporation kinetics or their motion when imposing von Karman swirling flows. This work is part of the AEROSOL project of DECLIC-EVO supported by CNES and aims to help the understanding of cloud microphysics which remains a critical open problem in the context of global warming.

In Thailand, the alteration of weather patterns has resulted in an increase in instances of irregular rainfall, contributing to the occurrence of droughts. The decline of water levels in dams, due to the combined effects of climate change and prolonged droughts, has had a significant impact on agricultural productivity. Drought has a profound effect on the terrestrial biosphere and the atmospheric water cycle and can also contribute to air pollution. Researchers have found a strong correlation between air pollution and drought severity. In response to this pressing issue, the Excellence Center of Space Technology and Research (ECSTAR) at King Mongkut’s Institute of Technology Ladkrabang has joined forces with TeroSpace company to launch an initiative aimed at promoting sustainable growth in Chiang Rai, a province in Thailand known for its rich biodiversity. ECSTAR and TeroSpace’s partnership on the sustainable growth initiative in Thailand’s Chiang Rai province focuses on expanding their collaboration to include international organizations such as the Centre National d’Etudes Spatiales (CNES), which will provide access to satellite imagery and climate and weather information to improve decision-making in various areas of development. CNES is a French organization in charge of space-related activities in France. The collaboration between France and Thailand for this project, in the context of the France-Thailand Year of Innovation 2023, will be crucial for the successful initiation and execution of this research project. The project aims to explore the relationship between air pollution and climate change through the deployment of air quality monitoring devices in designated locations, connected to a global data-sharing network. The results of this research will be valuable to policymakers as they consider the interplay between air pollution and climate change and make efforts to address these challenges.

Precise real-time kinematic (RTK) Global Navigation Satellite System (GNSS) positioning requires fixing integer ambiguities after a short initialization time. Originally, it was assumed that it was only possible at a relatively short distance from a reference station (<10 km), because otherwise the atmospheric effects prevent effective ambiguity fixing. Nowadays, through the use of VRS, MAC, or FKP corrections, the distances to the closest reference station have been increased to around 35 km. However, the baselines resolved in real time are not as far as in the case of static positioning. Further extension of the baseline requires the use of an ionosphere-weighted model with ionospheric delay corrections available in real time. This solution is now possible thanks to the Radio Technical Commission for Maritime (RTCM) stream of SSR corrections from, for example, Centre National d’Études Spatiales (CNES), the first analysis center to provide it in the context of the International GNSS Service. Then, ionospheric delays are treated as pseudo-observations that have a priori values from the CLK RTCM stream. Additionally, satellite orbit and clock errors are properly considered using space-state representation (SSR) real-time radial, along-track, and cross-track corrections. The following paper presents the initial results of such RTK positioning. Measurements were performed in various field conditions reflecting realistic scenarios that could have been experienced by actual RTK users. We have shown that the assumed methodology was suitable for single-epoch RTK positioning with up to 82 km baseline in solar minimum (30 March 2019) mid and high latitude (Olsztyn, Poland) conditions. We also confirmed that it is possible to obtain a rover position at the level of a few centimeters of precision. Finally, the possibility of using other newer experimental IGS RT Global Ionospheric Maps (GIMs), from Chinese Academy of Sciences (CAS) and Universitat Politècnica de Catalunya (UPC) among CNES, is discussed in terms of their recent performance in the ionospheric delay domain.

Testing the weak equivalence principle to a precision of 10−15 requires a quantity of data that give enough confidence on the final result: ideally, the longer the measurement the better the rejection of the statistical noise. The science sessions had a duration of 120 orbits maximum and were regularly repeated and spaced out to accommodate operational constraints but also in order to repeat the experiment in different conditions and to allow time to calibrate the instrument. Several science sessions were performed over the 2.5 years duration of the experiment. This paper aims to describe how the data have been produced on the basis of a mission scenario and a data flow process, driven by a tradeoff between the science objectives and the operational constraints. The mission was led by the Centre National d’Etudes Spatiales (CNES) which provided the satellite, the launch and the ground operations. The ground segment was distributed between CNES and Office National d’Etudes et de Recherches Aérospatiales (ONERA). CNES provided the raw data through the Centre d’Expertise de Compensation de Traînée (CECT: drag-free expertise centre). The science was led by the Observatoire de la Côte d’Azur (OCA) and ONERA was in charge of the data process. The latter also provided the instrument and the Science Mission Centre of MICROSCOPE (CMSM).

In Western Australia the vast majority of government subsidized dental specialist services is provided through the University of Western Australia (UWA). With predicted expanding demand for services and the high cost of providing specialist services it is important that access to specialist care is targeted at need. In this study the waiting lists for oral surgery services at UWA was analyzed to test the hypothesis that demand for oral surgical care is distributed evenly across the eligible population of Western Australia. Data were obtained from de-identified waiting lists for oral surgery at UWA. This data included all patients on the oral surgery waiting list from November 2001 to December 2003. Results indicated significantly less entries on the waiting list for people in remote and very remote postcode regions, and people living in postcode regions associated with a fixed government clinic were significantly more likely to be on the waiting list for oral surgery. The data presented identify that demand for specialist services is not driven through the expected factors of disease burden as indicated by socio-economic status, but by access to general dental services.
