B2. IAF SPACE COMMUNICATIONS AND NAVIGATION SYMPOSIUM

This symposium, organized by the International Astronautical Federation (IAF), examines developments in space-based systems, services, applications, and technologies as they relate to communication and navigation. Communication topics include fixed, broadcast, high-throughput, mobile, optical, and quantum communications. Navigation topics include position, velocity, and time determination and tracking for both relative and inertial reference frames. The symposium addresses geostationary, non-geostationary, and extra-terrestrial systems and constellations. The topics of IoT and M2M as they relate to communication and navigation are also applicable to this symposium.

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) for GNSS and alternative navigation satellite architectures (such as LEO constellations), ground and space-based navigation user equipment, sensor fusion algorithms, frequency and time transfer standards, crosslink ranging, precise orbit & satellite clock error determination, etc. Technologies should be applicable to position, velocity, and time determination and tracking, and integrity assurance on Earth, Moon, and other off-Earth platforms.
