CODE (Center for Orbit Determination in Europe) acts as one of the analysis centers International GNSS Service (IGS). One most important products are final series providing -- among others satellite orbits, clock corrections and station coordinates. Currently it includes GPS, GLONASS, Galileo satellites. The solution shall provide user community a direct access to IGS20 reference frame (the IGS-specific realization ITRF2020).Regarding this purpose, extension other systems, particular BDS...
To meet the demanding requirements in terms of accuracy and availability, GPS has introduced signals on L5 that are compatible to Galileo E5a signals. The signal was designed mitigate multipath poor performance harsh environments such as indoor, forests, areas affected by jamming. As L2 will become obsolete future, action must be taken take advantage modern type which is currently broadcast 19 out satellites. This particularly important for some future LEO satellites (e.g. EPS-SG) rely...
Abstract Maneuverability is essential for low Earth orbit (LEO) satellites to fulfill various operational objectives. However, the precise determination (POD) process might deteriorate due imperfect satellite orbital dynamics modeling. This article develops a generic POD strategy with maneuver handling LEO equipped high-performance spaceborne Global Navigation Satellite System (GNSS) receivers. Given time span of an executed maneuver, set constant thrust accelerations in body-fixed reference...
Commonly, Global Positioning System (GPS)-based precise orbit determination (POD) of a low Earth orbiting (LEO) satellite is conducted by introducing fixed GPS orbits and clock corrections that were derived in previous independent network solution using ground-based receivers only. There have been number studies showing the integration LEO observations can be advantageous global solutions, particularly when it comes to estimating geodetic parameters, such as Earth's center-of-mass. has an...
Abstract Inter-Satellite Links (ISLs) are intended to improve precision of orbit determination and satellite clock estimation. The ISLs provide a precise pseudorange measurements between satellites in specific constellation. study is preparatory assessment exploitation seven connectivity schemes the terms for three types constellations—Galileo-like with 24 on orbital planes, GPS-like six GPS real positions. first part focused detailed analysis various ISL schemes, considering geometry...
the US Naval Observatory together with Space Research Centre in Warsaw initiated Earth Orientation Parameters Combination of Prediction Pilot Project, which was accepted by IERS Directing Board.The goal this project is to determine feasibility combining (EOP) predictions on an operational basis.The ensemble EOPs are more accurate than results from individual predictions.The pole coordinate data different prediction contributors and computed U.S. studied statistical properties polar motion...

The models developed so far to account for the Non-Gravitational Perturbations (NGP) acting on satellites of Global Navigation Satellite Systems (GNSS) constitute present limit further improvements in Precise Orbit Determination (POD) these satellites. These are mainly based estimate empirical parameters (with goal absorb unknowns quantities) or use box-wing models. This unsatisfactory modeling has a negative impact both GNSS data over relatively short arcs, i.e. within classical navigation...
Abstract The Department of Planetary Geodesy the Space Research Centre PAS has been conducting research on a broad spectrum problems within field global dynamics Earth. In this report we describe investigations selected subjects concerning polar motion (modeling and geophysical interpretation Chandler wobble, hydrological excitation seasonal signals, search for optimal prediction methods), tectonic activity in region Książ Geodynamic Laboratory SRC, finally new joint Polish-Italian project...
Within the IGS, it was agreed that Precise Point Positioning (PPP) based on satellite orbit and clock corrections of IGS analysis centers allow a direct access to realization International Terrestrial Reference Frame (ITRF). This convention is considered convenient for all PPP users should not be changed in future. On other hand, groups determining GNSS orbits do prefer an origin frame related Earth instantaneous center mass since this reference gravitational force model. With background,...
Routine and occasional/emergency orbital maneuvers are essential for many satellites to maintain their optimal trajectory achieve a wide range of operational objectives in continuous way. However, incorrectly modelled highly dynamic changes the orbit during can significantly reduce accuracy precise determination (POD) an extent that is unacceptable scientific requirements. The aim this study investigate strategies maneuver handling Low Earth Orbiting (LEO) based on observations from on-board...
