“…For box-wing-type SRP models (Rodríguez-Solano, 2014a) the satellite is described by a small number of surfaces, while Ziebart (2004) established a more complex handling of SRP by finite element representation of the satellite and by ray-tracing techniques.…”

The Empirical CODE Orbit Model (ECOM) of the Center for Orbit Determination in Europe (CODE), which was developed in the early 1990s, is widely used in the International GNSS Service (IGS) community. For a rather long time, spurious spectral lines are known to exist in geophysical parameters, in particular in the Earth Rotation Parameters (ERPs) and in the estimated geocenter coordinates, which could recently be attributed to the ECOM. These effects grew creepingly with the increasing influence of the GLONASS system in recent years in the CODE analysis, which is based on a rigorous combination of GPS and GLONASS since May 2003.In a first step we show that the problems associated with the ECOM are to the largest extent caused by the GLONASS, which was reaching full deployment by the end of 2011. GPS-only, GLONASS-only, and combined GPS/GLONASS solutions using the observations in the years 2009-2011 of a global network of 92 combined GPS/GLONASS receivers were analyzed for this purpose.In a second step we review direct solar radiation pressure (SRP) models for GNSS satellites. We demonstrate that only even-order short-period harmonic perturbations acting along the direction Sun-satellite occur for GPS and GLONASS satellites, and only odd-order perturbations acting along the direction perpendicular to both, the vector Sun-satellite and the spacecraft's solar panel axis.Based on this insight we assess in the third step the performance of four candidate orbit models for the future ECOM. The geocenter coordinates, the ERP differences w. r. t. the IERS 08 C04 series of ERPs, the misclosures for the midnight epochs of the daily orbital arcs, and scale parameters of Helmert transformations for station coordinates serve as quality criteria. The old and updated ECOM are validated in addition with satellite laser ranging (SLR) observations and by comparing the orbits to those of the IGS and other analysis centers.Based on all tests we present a new extended ECOM which substantially reduces the spurious signals in the geocenter coordinate z (by about a factor of 2-6), reduces the orbit misclosures at the day boundaries by about 10%, slightly improves the consistency of the estimated ERPs with those of the IERS 08 C04 Earth rotation series, and substantially reduces the systematics in the SLR validation of the GNSS orbits.

“…ANGARA is able to calculate both radiation pressure and aerodynamic force coefficients using the same tools for building the satellite geometry. Similar techniques and software implementations are described in Ziebart [2004] and Ziebart et al [2005] for radiation pressure effects and in Fuller and Tolson [2009] for aerodynamics. The modeled accelerations can then be calculated by evaluating the same analytical equations as for the simple panel models.…”

“…The main improvement of ECOM2 over ECOM1 is the introduction of even (2/rev) and (4/rev) periodic terms in the direction of direct solar radiation (Sun-Earth direction or D-axis of the ECOM decomposition). Like other modern SRP models, such as the ones introduced by Ziebart (2004), Ikari et al (2013), Rodriguez-Solano et al (2014), Springer et al (2014), , or , ECOM2 is able to take into account the variation of the direct solar radiation pressure within an orbit revolution caused by the variation of the illuminated cross-section of a rotating, elongated satellite body. The ECOM1, in contrast, assumes that the force in the direction of direct solar radiation (D-axis of the ECOM decomposition) is constant within an orbit arc, which would be true for spherical satellite bodies and is a good approximation for cubic satellite bodies.…”

This article describes the processing strategy and the validation results of CODE's MGEX (COM) orbit and satellite clock solution including the satellite systems GPS, GLONASS, Galileo, BeiDou, and QZSS. The validation with orbit misclosures and SLR residuals shows that the orbits of the new systems Galileo, BeiDou, and QZSS are affected by modelling deficiencies with impact on the orbit scale (e.g., antenna calibration, Earth albedo, transmitter antenna thrust). Another weakness is the attitude and solar radiation pressure (SRP) modelling of satellites moving in the orbit normal mode-which is not yet correctly considered in the COM solution. Due to these issues we consider the current state COM solution as preliminary. We, however, use the long time series of COM products for identifying the challenges and for the assessment of model improvements. The latter is demonstrated on the example of the solar radiation pressure (SRP) model, which has been replaced by a more generalized model. The SLR validation shows that the new SRP model significantly improves the orbit determination of Galileo and QZSS satellites at times when the satellite's attitude is maintained by yaw-steering. The impact of this orbit improvement is also visible in the estimated satellite clocks-demonstrating the potential use of the new
