Broadcast ephemerides for LEO augmentation satellites based on nonsingular elements
GPS Solutions, 2021 Low earth orbit (LEO) satellite constellations have the potential to augment global navigation satellite system services. Among the ongoing tasks of LEO-based navigation, providing broadcast ephemerides that satisfy the accuracy requirement for positioning, navigation, and timing is one of the most critical prerequisites.

An improved method for real-time PPP timing and time transfer with broadcast ephemerides
Measurement Science and Technology, 2022 Abstract Due to the problem of network communication, it is difficult to ensure the reliability of real-time precise point positioning (PPP) timing/time transfer with real-time precise products. With the continued reduction in the signal-in-space range error, the performance and feasibility of GPS and Galileo PPP ...

Precise On-Board Navigation of LEO Satellites with GNSS Broadcast Ephemerides
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2020 The availability of orbit information with high precision and low latency is a key requirement for many Earthobservation missions, predominantly in the field of radio occultation. Traditionally, precise orbit determination solutions of low-Earth orbit (LEO) satellites are done offline on the ground after dwonloading GNSS measurements and required ...

GPS positioning with broadcast and precise ephemerides
SICE '95. Proceedings of the 34th SICE Annual Conference. International Session Papers, 2002 The precise ephemeris and space vehicle clock corrections computed routinely by the International GPS Service for Geodynamics (IGS) under the International Association of Geodesy (IAG) is accurate to less than submeter. Since the precise orbit/clock is free from selective availability (SA) errors, accurate point positioning and orbit determination can ...
