The Pioneer anomaly in covariant theory of gravitation.

The difference of equations of motion in the covariant theory of gravitation and in the general theory of relativity is used to explain the Pioneer anomaly. Calculation shows that the velocities of a spacecraft in both theories at equal distances can differ by several centimetres per second. This leads also to a possible explanation of the flyby anomaly and comet disturbances, which are not taken into account by the general theory of relativity. [ABSTRACT FROM AUTHOR]

Les differences entre les équations de mouvement dans la théorie covariante de la gravitation et dans la théorie générale de la gravitation sont utilisées pour expliquer 'l'anomalie Pioneer'. Le calcul montre que les vélocités des sondes spatiales dans les deux theories aux distances différentes peuvent se différencier à plusieurs cm/s. Cela amène à l'explication possible de l'anomalie 'flyby' et aux perturbations de la comète qui ne sont pas pris en compte dans la théorie générale de la relativité. [ABSTRACT FROM AUTHOR]
