像其他光学天体测量技术一样，摄影天顶管（PZT）在过去的地球自转观测中发挥了关键作用，它也有可能通过利用自动观测与自补偿的管倾斜被应用到其他几个观测。本文提出了在后SELENE使命中，利用PZT等精度为1毫弧秒（1 mas）的小型望远镜，从月球表面直接观测月球自转，研究月球自转动力学的原位月球定向测量（In-situ Lunar Orientation Measurement，简称月球定向测量）方案。我们的第二个应用是通过结合PZT测量的垂直偏差和全球定位系统（GPS）或全球导航卫星系统（GNSS）测量的位置来获得地球上的局部重力场。为此目的所要求的准确度并不像标准那样严格。我们已经研制了一个用于月球探测的望远镜的面包板模型（BBM），并进行了一些实验，以了解在类似于月球环境的高真空、大温度变化和灰尘条件下驱动机构的性能。我们还表明，可以通过使用精度优于1质量的简单模型来校正均匀温度变化对光学系统的影响。该模型有可能达到1 mas的精度，根据实验和模拟的结果。
Like other optical astrometric techniques, the Photographic Zenith Tube (PZT) has played a key role in the past observations of the Earth rotation, and it also has a potential to be applied to several other observations by taking advantage of automatic observations with self compensation of tilt of the tube. We here proposeIn-situLunar Orientation Measurement (ILOM) to study lunar rotational dynamics by direct observations of the lunar rotation from the lunar surface by using a small telescope like PZT with an accuracy of 1 milli-seconds of arc (1 mas) in the post-SELENE mission. Our second application is to obtain local gravity field on the Earth by combining deflection of the vertical measured by PZT and the position measured by Global Positioning System (GPS) or Global Navigation Satellite System (GNSS). The accuracy required for this purpose is not as strict as ILOM. We have already developed a Bread Board Model (BBM) of the telescope for ILOM and made some experiments in order to know the performance of the driving mechanism under a similar condition to the lunar environment showing high vacuum, large temperature change and dusty condition. We have also shown that it is possible to correct the effects of uniform temperature change upon the optical system by using a simple model with an accuracy of better than 1 mas. This model has the potential to attain the accuracy of 1 mas, based on the results of the experiments and the simulations.
