Precision orbit determination for Topex
Advances in Space Research, 1990The ability of radar altimeters to measure the distance from a satellite to the ocean surface with a precision of the order of 2 cm imposes unique requirements for the orbit determination accuracy. The orbit accuracy requirements will be especially demanding for the joint NASA/CNES Ocean Topography Experiment (Topex/Poseidon).

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

Antenna for precise orbit determination
Acta Astronautica, 2009Abstract The ESA SWARM mission will consist of three satellites that will measure the Earth magnetic field. The system calls for metre accuracy knowledge of the measurement locations. To achieve this a GPS receiver is used. At least four GPS signals are tracked to determine the code and carrier ranges, from which the position can be derived.

Precise Orbit Determination of CubeSats
2022CubeSats are faced with some limitations, mainly due to the limited onboard power and the quality of the onboard sensors. These limitations significantly reduce CubeSats' applicability in space missions requiring high orbital accuracy. This thesis first investigates the limitations in the precise orbit determination of CubeSats and next develops ...

Simulation of precise orbit determination of lunar orbiters
Chinese Astronomy and Astrophysics, 2005Abstract Based on the ongoing Chinese lunar exploration mission, i.e. the “Chang'e 1” project, precise orbit determination of lunar orbiters is analyzed for the actual geographical distribution and observational accuracy of the Chinese united S-band (USB) observation and control network as well as the very long baseline interferometry (VLBI) tracking

Precise orbit determination for lunar satellite
Acta Astronautica, 2002Lunar satellite in the polar orbit is the most popular concept in the recent and future lunar exploration missions for finding the water and other objectives. The motion and perturbed solution of lunar satellite are distinctly different from that of the earth satellite because the central body of the satellite, the Moon, is not the same as the Earth ...
