  • Antennas for High-Precision GNSS Applications
    Antennas for High-Precision GNSS Applications Roshni Prasad Associate Engineer – RF & Connectivity Abracon, LLC Antennas for High-Precision GNSS Applications | Abracon LLC Abstract: The increasing interest in high-precision GNSS/GPS services has led to the development of novel antenna solutions to service various end-customer applications in markets such as agriculture, recreation, surveying & mapping, and timing. Multi-band receivers and antennas are required to derive a higher-precision rate on positioning. However, using dedicated antennas for widely separated multi- band support may introduce several challenges in the design, including increased occupancy in board space and coupling. This application note reviews how these challenges are addressed by employing a single multi-band antenna. The discussion primarily focuses on Abracon’s internal and external antenna solutions that can cover multiple GPS and/or GNSS bands as a single entity for precision positioning applications.

Introduction to GNSS What is GNSS? Why is GNSS needed? What are the available constellations? Global Navigation Satellite System (GNSS) is a satellite-based navigation and positioning system that offers a prediction of coordinates in space, with respect to velocity and time, to assist in the navigation and positioning of receiver systems. The service is supported by various global constellations, including GPS (U.S.), GLONASS (Russia), Galileo (Europe), and regional constellations such as BeiDou (China), QZSS (Japan) and IRNSS (India).

In-land deployed systems - Are the most common, based on ground stations emitting radiofrequency signals received by on-board equipments to calculate flight position. B. Satellite navigation systems – First stablished by U.S. in 1959 called TRANSIT (by the time Russia developed TSIKADA); in 1967 was open to civil navigation; 1973 GPS was developed by U.S., then GLONASS, then GALILEO. C. Inertial navigation systems – Autonomous navigation systems based on inertial forces, providing constant information on the position of the flight and parameters of speed and direction (e.g. when flying above the ocean and there are no ground segments to provide support). Requirements for performance of Navigation Systems: According to the International Civil Aviation Organization (ICAO) there are four main requirements: • The accuracy means the level of concordance between the estimated position of an aircraft and its real position. • The availability is the portion of time during which the system complies with the performance requirements under certain conditions. • The integrity is the function of a system that warns the users in an opportune way when the system should not be used.

Currently, it is one of two fully operational Global Navigation Satellite Systems (GNSS), and two more are in the implementation stage. The new European Galileo and Chinese BeiDou Navigation Satellite System (BDS) already provide usable signals, and both GPS and GLONASS are currently undergoing significant modernization, which adds more capacity, more signals, better accuracy, and interoperability, etc. Meanwhile, there has been significant technological development in GNSS equipment (in some cases, even at low-cost), which is now able to collect measurements at much higher rates (up to 100 Hz), thus presenting new possibilities. On the one hand, the new developments in GNSS offer a broad range of new applications for solid and fluid Earth investigations, in both post-processing and real-time; on the other, this results in new problems and challenges in data processing that increase the need for GNSS research.

  • Applications of the Beidou Navigation Satellite System (December 2018)
    © China Satellite Navigation Office 2018 Applications of the BeiDou Navigation Satellite System (December 2018) China Satellite Navigation Office © China Satellite Navigation Office 2018 © China Satellite Navigation Office 2018 Preface The BeiDou Navigation Satellite System (hereinafter referred to as the BDS) has been independently constructed and operated by China with an eye to the needs of the country’s national security and economic and social development. As a space infrastructure of national significance, the BDS provides all-time, all-weather and high-accuracy positioning, navigation and timing services to global users. In the late 20th century, China started to explore a path to develop a navigation satellite system suitable for its national conditions, and gradually formulated a three-step strategy of development: to complete the construction of the BDS-1 and provide services to the whole country by the end of 2000; to complete the BDS-2 construction and provide services to the Asia-Pacific region by the end of 2012; and to complete the BDS-3 construction and reach world-class standards around 2020. China has started its third step of construction, putting in place the basic system of BDS-3 at the end of 2018 and providing navigation services the world over. “BDS is developed by China, and dedicated to the world”. To benefit the world with reliable services from China, the BDS follows the basic principles of “independence, openness, compatibility and gradualness”. The BDS is one of the four key GNSS suppliers recognized by the United Nations International Committee on Global Navigation Satellite Systems (ICG), and a major achievement of China in the past four decades since the country’s reform and opening up.

Composed of students and young professionals, Youth for GNSS aims to recognize and promote the ways in which Global Navigation Satellite Systems (GNSS) and Satellite Based Augmentation Systems (SBAS) can benefit society. With the future and health of our planet and its citizens a primary concern, YGNSS aims to secure and optimize how GNSS -based applications and technology will benefit society by promoting compatibility and interoperability of GNSS through a network of systems. In addition to the development and improvement of technology, applications, education, and outreach in regions where GNSS is already established, it is the goal of YGNSS to analyze and promote the importance and impact of GNSS technology in areas with less developed infrastructure, such as in developing countries and in the Arctic. In this paper, drivers of change in the Arctic are discussed based on the impact of GNSS as tools for scientific applications and for strengthening and promoting interoperability of navigation, positioning, and timing systems.
