Simulation of precise orbit determination of lunar orbiters [PDF]
Abstract 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 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

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.

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 GRACE
Advances in Space Research, 2003Abstract The twin, co-orbiting GRACE (Gravity Recovery and Climate Experiment) satellites were launched in March 2002. The primary objective of the GRACE mission is to determine the Earth's gravity field and its temporal variations with unprecedented accuracy. To satisfy this objective as well as other applications (e.g.

Experiment for Precise Orbit Determination on InnoCube
2023Computing platforms, such as FPGAs and SoCs, are delivering high performance systems in a form factor suitable for small satellites. By offering system-on-modules, technology entry has been drastically lowered. A first step to achieve these higher processing capabilities in orbit is envisioned in the EPISODE payload of the 3U InnoCube satellite, set to

Precise Orbit Determination of the MESSENGER Spacecraft
Journal of Guidance, Control, and DynamicsThe NASA MESSENGER mission explored Mercury for more than four years to investigate the properties of the planet. To safely operate in the harsh conditions around Mercury, the spacecraft was in a highly eccentric orbit with a low periapsis altitude. The radiation environment had a strong impact on the spacecraft orbit evolution because of the proximity

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 ...
