Thermal rediation and the Pioneer anomaly |
|
Abstract |
The disturbance acceleration resulting from thermal recoil forces for the Pioneer 11 spacecraft is presented. An analytical test case including the main power sources (RTGs) and the main reflective surface (high gain antenna) is formulated and processed. The results show that for a precise computation of the effect the reflecting and absorbing surface geometries have to be modeled in detail and that the effect of thermal recoil forces cannot be neglected on the level of the Pioneer anomaly (PA). The limitations of the method are discussed and the need for new improved modeling techniques for a complete assessment of the problem is underlined. |
