Precise Orbit Determination of GPS Satellites for Real Time Applications [PDF]

Journal of Astronomy and Space Sciences, 2001
The accuracy of GPS applications is heavily dependent on the satellite ephemeris and earth orientation parameter. Specially applications like as the real time monitoring of troposphere and ionosphere require real time or predicted ephemeris and earth ...

Positioning Technology Without Ground Control Points for Spaceborne Synthetic Aperture Radar Images Using Rational Polynomial Coefficient Model Considering Atmospheric Delay

Applied Sciences
This study addresses the issue of atmospheric delay correction for the rational polynomial coefficient (RPC) model associated with spaceborne synthetic aperture radar (SAR) imagery under conditions lacking ephemeris data, proposing a novel approach to ...

A 16-parameter GEO Broadcast Ephemeris [PDF]

Journal of Geodesy and Geoinformation Science, 2018
Currently, the broadcast ephemerides used in GEOs are same as those of the MEOs and IGSOs in the BeiDou navigation constellation. However, a trade-off strategy, i.e.

ARMA Prediction of SBAS Ephemeris and Clock Corrections for Low Earth Orbiting Satellites

International Journal of Aerospace Engineering, 2015
For low earth orbit (LEO) satellite GPS receivers, space-based augmentation system (SBAS) ephemeris/clock corrections can be applied to improve positioning accuracy in real time.

The K2 and TESS Synergy. III. Search and Rescue of the Lost Ephemeris for K2's First Planet

The Astronomical Journal
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 ± 0.1 R _⊕ , 9.7 ± 1.2 M _⊕ ) orbiting a relatively bright ( K _S = 8.03) K-dwarf star on a 9.1 day period. Unfortunately, due
