对火卫一和火卫二从1877年到1973年的运动进行了广泛的分析。为这两颗卫星确定了由Struve最先开发的轨道模型参数的新值。新的轨道参数组与威尔金斯和辛克莱找到的类似精度的解决方案相竞争。火卫一的经向长期加速度等于+(0.107±0.011)×10−7deg day−2。忽略其中一组对立面时，加速度的大小几乎不受影响。用极大的不确定度确定了DEIMOS的加速度：+(0.06±0.34)×10−9度−2。轨道参数的值似乎是一致的，因为从每颗卫星的运动推断的火星极点的质量、扁率和坐标在这两种情况下都有相似的值。
An extensive analysis of the motion of Phobos and Deimos from 1877 to 1973 has been fulfilled. The new values of the parameters of the orbital model first developed by Struve have been determined for both satellites. The new sets of the orbital parameters compete with the solutions of similar accuracy found by Wilkins and Sinclair. A secular acceleration in longitude of Phobos is found to be equal to +(0.107±0.011)×10−7deg day−2. The value of the acceleration is little affected when one or another group of oppositions is omitted. The acceleration of Deimos is determined with great uncertainty: +(0.06±0.34)×10−9deg day−2. Values found for the orbital parameters seem to be in good agreement since the mass, oblateness and coordinates of the pole of Mars inferred from the motion of each satellite have similar values in both cases.
