Abstract

The scope of this work is to present a new approach for estimating the attitude of GNSS satellites with horizontal offset antennas. Previously, studies have shown that the attitude deviation from nominal models can successfully be measured by Reverse Kinematic Point Positioning (RKPP) approaches. Here, a new approach is studied which uses ionosphere-free observation residuals to estimate the yaw angle of these satellites. This approach is analyzed and applied to a two months set of data generated by observing GPS block IIF satellites. The method is derived and tested against previous works obtained using the RKPP method and the results coincide with findings of previous studies. Features such as the linear drift of yaw maneuvers during eclipse seasons, observed inversion of maneuvers performed under certain low Sun angles, as well as drifting of rotation rates are measured and their values are shown to be consistent with previous findings.
