Precise orbit determination for the orbital phase of BepiColombo
The BepiColombo spacecraft, designed by ESA and JAXA, is expected to begin its scientific phase in orbit around Mercury in early 2027. Among the scientific investigations is the Mercury Orbiter Radio-science Experiment (MORE), which will exploit a multi-frequency microwave tracking system with an advanced Ka-band transponder to achieve its objectives ...

FedSat Orbit Determination: Results From Daily GPS Flight Code Observations
, 2003 The Australian Federation Satellite, FedSat, was successfully launched into a 780-km low-earth orbit on 14 December 2002. Since then, the onboard Blackjack GPS receiver has operated on a duty cycle basis, providing effective data sets at an average of 10

Satellite on-board solutions for precise orbit determination on Earth and Moon orbit.
Precise Orbit Determination, which is the problem of finding the satellite ephemeris by estimating the satellite position and velocity based on Earth observations data, has always been one of the most important aspects of satellite navigation. Satellite positioning is used daily by smartphones to provide several features and also by military personnel.

Precise orbit determination for the GOCE satellite using GPS
Advances in Space Research, 2007Abstract Apart from the gradiometer as the core instrument, the first ESA Earth Explorer Core Mission GOCE (Gravity field and steady-state Ocean Circulation Explorer) will carry a 12-channel GPS receiver dedicated for precise orbit determination (POD) of the satellite.

Precise Orbit Determination for NavIC Satellites
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021Precise Orbit Determination (POD) is an important process for navigation applications like Precise Point Positioning (PPP) and Real Time Kinematics (RTK). Earlier researchers have carried out extensive research for GNSS constellations placed in Medium Earth Orbits (MEO) having dynamic behaviour different from Geo-Synchronous Orbits (GSO) satellites. In
