“…The precision of the HASDM model was evaluated by Bowman and Storz (2002), and they showed that the precision at altitudes between 200 and 800 km can be reduced to only 6-8%, which is much better than the results in our study and Doornbos et al (2008). This is mainly attributed to the fact that the HASDM makes use of the SSN radar tracking observations as input, and re-estimates the parameters of the Jacchia model using the DCA (Dynamic Calibration Atmosphere) method during the precise orbit determination process.…”

“…The solar radiation and geomagnetic indices generated by the SOLAR2000 model were also used because of their superior accuracies. The results showed that the Bowman method can reduce the density model error to 6-8% at the altitude of 200-800 km, and the drag-induced orbit prediction error by using this model can be decreased by 40% (Bowman and Storz, 2002;Storz et al, 2005).…”

“…Daily temperature corrections to the US Air Force High Accuracy Satellite Drag Model's (HASDM) Bowman and Storz, 2002) modified Jacchia 1970 atmospheric model have been obtained on 28 satellites during the period . Approximately 225,000 daily temperature values were obtained using a special energy dissipation rate (EDR) method (Bowman et al, 2004a), where radar and optical observations are fit with special orbit perturbations.…”

“…Thus, in contrast with the accelerometer methods described above, this category uses sparse measurements having lower accuracy, but on a larger set of satellites. Much work in this area has been performed by the U.S. Air Force in support of its High Accuracy Satellite Drag Model (HASDM), [11][12][13][14][15][16] which uses tracking measurements to estimate a correction to the Jacchia 70 empirical density model. Corrections to the exospheric and inflection point temperatures in the vertical temperature profile are represented as two separate spherical harmonic expansions, varying in the literature from second degree and order 13 up to a 4×0 expansion.…”
