Technical programme

B2.1. Space-based PNT (Position, Navigation, Timing) Architectures, Applications, and Services

This session is focused on advances in space-based navigation systems, including the existing global systems (Beidou, Galileo, GLONASS, GPS) and regional systems (EGNOS, IRNSS, QZSS, WAAS), as well as proposed and emerging new space-based systems. The session also addresses advances in the services and applications of those systems for position, velocity, and time determination and tracking, and integrity assurance on Earth, Moon, and potentially other bodies of the solar system.

B2.2. Space-based PNT (Position, Navigation, Timing) Sensors and Systems

This session is focused on advances in technology applicable to space-based navigation systems. Technologies include hardware or software necessary for the entire navigation system (spacecraft, monitor and control system, end-user equipment) such as: sensors, star trackers, sensor fusion algorithms, space-born frequency standards, crosslink ranging techniques, etc. Technologies should be applicable to position, velocity, and time determination and tracking, and integrity assurance on Earth, Moon, and potentially other bodies of the solar system.

B2.3. Advance Higher Throughput Communications for GEO and LEO satellites

It also includes spectrum allocations and regulations issues, and impacts of Space Debris and optical pollution to satellite communications for new systems/services, and systems modeling.

B2.6. Cubesat, Internet of Things, and Mobile Direct Communications

This session is focused on small satellite, IoT and mobile communication services that can communicate directly with 3GPP mobile phone terminals including all aspects of space communications, services, architecture and infrastructure: Narrow Band (NB)-IoT, 3GPP IoT terminals; LoRa IoT terminals; Low Power Wide Area (LPWA); Non-Terrestrial Network (NTN); cube-, pico-, nano-, micro-satellites; High Altitude Platform Station (HAPS); in-orbit, on-ground demonstrations and results; present and future scenarios; next generation systems and applications; terrestrial-based systems; small satellites; Earth observation satellites; devices; subsystems and components; laboratory demonstration hardware; site-diversity techniques; modulation formats. Both terrestrial and satellite networks will be available at the same terminal, and coverage is expected to expand significantly.

B2.7. Advances in Space-based Network and Communication Technologies

This session is focused on all aspects of advanced novel technologies for space-based networks and communications and data relay of payload, spacecraft, and Earth station. It covers applications ranging from those used in nanosatellites to those applicable to large, high throughput systems, and integrated applications and services. It includes modulation and coding, propagation, power amplifiers, adaptive transmit technologies, inter-satellite links, antenna (including phased array) design, Q/V/W/E band technologies, onboard processing, digital payload technologies, security, and other technology relevant to satellite communication.

B2.8-GTS.3. Space Communications and Navigation Global Technical Session

This is a hybrid (virtual and in person) session that targets a global audience where developments in a wide range of satellite communication and space-based PNT (position, navigation, timing) topics are presented and discussed. Communication topics include fixed, mobile, broadcasting, and data relay technologies and services. Space-based PNT topics include sensors, systems, architectures, applications, and services. Topics ranging from Earth orbit to interplanetary space can be addressed. Authors are welcome to either present their work in person at the conference or remotely via the IAF's online platform. This session offers authors the unique opportunity to directly engage an audience beyond just the on-site attendees and is co-sponsored by the Space Communications and Navigation Committee and the Workforce Development/Young Professionals Programme Committee.

B2.IP. Interactive Presentations - IAF SPACE COMMUNICATIONS AND NAVIGATION SYMPOSIUM

This session offers a unique opportunity to deliver your key messages in an interactive presentation on any of the subjects of Space Communications and Navigation addressed in the classic Sessions. The presentation will be displayed on a digital screen in a dedicated location and available for view by all Congress attendees for the entire Congress week. In addition, one afternoon is dedicated exclusively for the attendees to view the Interactive Presentations, and the author will be assigned a specific ten-minute slot to personally present the topic and interact with the attendees present. The Interactive Presentation may take advantage of all electronic display capabilities, such as: PowerPoint charts, embedded hot links, pictures, audio and video clips etc. An award will also be presented to the author of the best Interactive Presentation in the B Category at a special ceremony. An Abstract that follows the standard format must be submitted by the deadline for standard IAC abstracts.
