Real-time high-precision joint orbit determination of GPS and LEO using SRIF

Measurement Science and Technology
Low Earth Orbit (LEO) satellites have the advantages of high flight velocity and minimal influence from external environmental factors on onboard observation. Integrating LEO satellite observations with ground observations can improve the accuracy and convergence performance of GPS and LEO real-time orbit determination, which can simultaneously meet ...

Space GNSS Receiver Performance Results With Precise Real-Time On-board Orbit Determination (P2OD) in LEO Missions

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019
The paper presents a low-cost Space GNSS receiver for Cubesats promoted by European Space Agency, with the aim of providing real-time precise on-board orbit determination (P2OD). The activity is oriented to a Low-Earth Orbit in-orbit demonstration of the concept in 2020-2021. The GNSS Receiver is based on Deimos’ FPGA-based dual frequency GPS / Galileo

Real-time LEO satellite precise orbit and clock determination for augmenting GNSS: Strategies and Challenges

To realize the various benefits brought by Low Earth Orbit (LEO) satellites in single-receiver high-precision GNSS-based Positioning Navigation and Timing (PNT) services, LEO satellite orbits and clocks need to be processed and delivered to users in real-time with precision of a few centimeters.
