This book was released on 2019-09-19 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability and performance of global navigation satellite systems (GNSS) signals at high altitude is documented as the GNSS Space Service Volume (SSV). While different definitions of the SSV exist and may continue to exist for the different service providers, within the context of this booklet it is defined as the region of space between 3,000 km and 36,000 km above the Earth's surface, which is the geostationary altitude. For space users located at low altitudes (below 3,000 km), the GNSS signal reception is similar to that for terrestrial users and can be conservatively derived from the results presented for the lower SSV in this booklet.

Book excerpt: The Global Positioning System (GPS) has revolutionized the measurement of position, velocity, and time. It has rapidly evolved into a worldwide utility with more than a billion receiver sets currently in use that provide enormous benefits to humanity: improved safety of life, increased productivity, and wide-spread convenience. Global Navigation Satellite Systems summarizes the joint workshop on Global Navigation Satellite Systems held jointly by the U.S. National Academy of Engineering and the Chinese Academy of Engineering on May 24-25, 2011 at Hongqiao Guest Hotel in Shanghai, China. "We have one world, and only one set of global resources. It is important to work together on satellite navigation. Competing and cooperation is like Yin and Yang. They need to be balanced," stated Dr. Charles M. Vest, President of the National Academy of Engineering, in the workshop's opening remarks. Global Navigation Satellite Systems covers the objectives of the workshop, which explore issues of enhanced interoperability and interchangeability for all civil users aimed to consider collaborative efforts for countering the global threat of inadvertent or illegal interference to GNSS signals, promotes new applications for GNSS, emphasizing productivity, safety, and environmental protection. The workshop featured presentations chosen based on the following criteria: they must have relevant engineering/technical content or usefulness; be of mutual interest; offer the opportunity for enhancing GNSS availability, accuracy, integrity, and/or continuity; and offer the possibility of recommendations for further actions and discussions. Global Navigation Satellite Systems is an essential report for engineers, workshop attendees, policy makers, educators, and relevant government agencies.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the highly anticipated sequel to the previous volume under the same title, dedicated to presenting a diverse range of timely and valuable contributions on the legal and policy related questions evoked by satellite constellations, including emerging mega-constellations. Given the proliferation of activities in the field of satellite constellations, and the critical roles they play in supporting and enabling communication, navigation, disaster monitoring, Earth observation, security and scientific activities, the insights of legal and policy experts from around the world have been gathered in this second volume to help expand the scientific literature in this precious field. Topics range from legal obstacles and opportunities facilitating small satellite enterprise for emerging space actors, international cooperation in the compatibility and interoperability of navigation systems, the designation of satellite constellations as critical space infrastructure, to an analysis of the paradigm shift which has occurred over the last decade to make the proliferation of small satellite constellations possible, and more.

This book was released on 2012-12-06 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers contained in this Volume of Proceedings have been collected from an international Workshop entitled 'Mission Design and Implementation of Satellite Constellations' which was held in Toulouse, France, in November 1997. This Workshop represented the first international gathering of the specialists in this currently very active field of research activity. The initiative to organise a Workshop around this theme was conceived during the Congress of the International Astronautical Federation (IAF) in Beijing, China, in October 1996. On that occasion, the IAF explored concepts and possibilities for the conduct of small specialist Workshops and Symposia of current interest. Topical, interesting, and focused themes in the general field of space technology (both theories and applications) will be selected for these Symposia. They aim at offering a dedicated forum at international level for specialists and experts to exchange their views and experiences on recent and future developments within the selected theme. These specialist Workshops and Symposia supplement the comprehensive annual IAF Congresses which cover all aspects of space technology and draw a correspondingly diverse audience.

The success of previous ISU symposia suggests that the ISU has developed a unique and winning formula for a novel type of symposium. The characteristics of ISU symposia are that they: • Adopt a broad, and interdisciplinary, perspective • Address all aspects of the subject, ranging from policy, business, organisational, and legal issues to technical and scientific topics • Foster a constructive dialogue among very different sectors of the space community, and • Allow ample time for interactive discussions. The present Symposium is no exception. It considers the very timely topic of space-based systems for global positioning and navigation, ranging from the GPS system developed by the US military to the Russian GLONASS system, and on to the future European Galileo system. Other nations are planning regional augmentation systems.

Download or read book Small Satellite Missions for Earth Observation written by Rainer Sandau and published by Springer Science & Business Media. This book was released on 2010-01-23 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was compiled from contributions given at the 7th IAA Symposium on Small Satellites for Earth Observation, May 4–8, 2009, Berlin (IAA – International Academy of Astronautics). From the 15 sessions for oral presentations and two poster sessions, 52 contributions were selected which are representative for the new developments and trends in the area of small satellites for Earth observation. They re ect the potentials of a diversity of missions and related technologies. This may be based on national projects or international co-operations, single satellites of constellations, pico-, nano-, micro- or mini-satellites, developed by companies, research institutions or agencies. The main focus is on new missions to monitor our Earth’s resources (Part I), and the environment in which our Earth is emb- ded (Part II). Part III deals with distributed space systems, a unique feature of small satellites and in most cases impractical to do with large satellites. Here we concentrate on constellations of satellites with focus on future missions relying on co-operating satellites. For all the new developments and projects we need well e- cated specialists coming from the universities. Many universities included already the development and implementation of small satellites in their curriculum. The u- versity satellites chapter (Part IV) shows the high quality which is already reached by some of the universities worldwide.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of Global Positioning System (GPS) and upcoming Global Navigation Satellite System (GNSS) signals for Geostationary Orbit (GEO) and Highly Elliptical Orbit (HEO) space missions has special design challenges. Such missions are at an altitude above the altitude of the GNSS constellations. Consequently, the signals reaching an onboard receiver originate from GNSS satellites on the opposite side of Earth. The received signals are 10 to 100 times weaker with limited satellite spatial diversity. GNSS signal reception at GEO and beyond is dependent on accurately modelling the side lobes of the GNSS satellite transmit antenna array. Starting with the GPS Block III satellites, the GPS Interface Control Document (ICD) provides specifications on the gain characteristics of the main lobe of the transmit antenna array. There is no information in the literature that describes the side lobes of the transmit antenna pattern. Pictures of antennas onboard the Galileo Full Operational Capability (FOC) satellites indicates a transmit array of 28 patch antennas. No information can be found in the literature that characterizes the gain pattern for the Galileo FOC transmit antenna array. In this dissertation, GPS Block III and Galileo FOC transmit array main and side lobe gain patterns have been reversed engineered using computational electromagnetics. Using the reverse engineered transmit antenna gain patterns, satellite visibility and accuracy is evaluated onboard a GEO satellite using a combined GPS plus Galileo satellite constellation. Traditional ground-based satellite laser ranging has accuracy in the kilometer class. Leveraging both the main lobe and side lobes of a combined GPS plus Galileo constellation can result in at least two orders of improvement compared to ground-based approaches. Persistent autonomous RMS 3-D positioning accuracies of 9 -- 15 m can be achieved at GEO. Specular multipath resulting from the body structure and solar arrays is the dominant error source onboard Low Earth Orbit (LEO) satellites. In particular, solar panel induced specular reflections onboard the International Space Station (ISS) can cause up to 50m in GPS positioning error. Conventional multipath mitigation strategies are insufficient overcome this problem. In this work, a novel implementation of adaptive digital beamforming and predictive antenna nulling is demonstrated to overcome multipath. Using live sky data, a 4x decrease in positioning errors is achieved using a simple four element antenna array. A combined GPS + Galileo system is chosen to leverage the common L1 signal which will be transmitted by both constellations. Given the rather weak signal reception at GEO and beyond, custom signal acquisition algorithms are required. Such implementation cannot be found in commercial GNSS receivers. A real-time L1 C/A receiver with adaptive digital beamforming has been developed. The receiver has been implemented on the Xilinx Virtex-5QV rad-hard FPGA. To overcome the need for an external coprocessor, a dual core LEON3 processor has also been implemented within the same FPGA. Receiver performance and design methodologies adopted in its implementation are discussed in this thesis.

This book was released on 2003-07-03 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report addresses the transition of research satellites, instruments, and calculations into operational service for accurately observing and predicting the Earth's environment. These transitions, which take place in large part between NASA and NOAA, are important for maintaining the health, safety, and prosperity of the nation, and for achieving the vision of an Earth Information System in which quantitative information about the complete Earth system is readily available to myriad users. Many transitions have been ad hoc, sometimes taking several years or even decades to occur, and others have encountered roadblocksâ€"lack of long-range planning, resources, institutional or cultural differences, for instanceâ€"and never reached fruition. Satellite Observations of Earth's Environment recommends new structures and methods that will allow seamless transitions from research to practice.
