Precise Orbit Determination [PDF]
, 2017 Precise Orbit Determination (POD) is an integral part for analyzing measurements from space geodetic techniques such as Satellite Laser Ranging (SLR) and Global Navigation Satellite Systems (GNSS) such as the Global Positioning System (GPS). In the last two decades, POD based on GPS data has furthermore been established as one of the standard ...

Precise Orbit Determination of CubeSats [PDF]
, 2022 CubeSats 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 ...

Precise Orbit Determination of GPS-36 Satellite Using Satellite Laser Ranging [PDF]
Journal of Astronomy and Space Sciences, 2002 Satellite laser ranging is a technique for precisely measuring the range between a laser station and a satellite that is equipped with retro-reflectors. SLR technique was first used for Beacon-B satellite in 1964 with the ranging accuracy of meter level.

Precise Orbit Determination for ADEOS-II [PDF]
, 2006 We performed the precise orbit determination of ADEOS-II using single frequency GPS data and reviewed the results. JAXA precise orbit determination system is called “GUTS (Global and high accUracy Trajectory determination system)”. In the 18th ISSFD, we reported that the accuracy of precise orbit determination achieved about 51cm.
