Разработан зенитный телескоп для наблюдения градиента силы тяжести и вращения луны, а также создана опытная модель для наземных экспериментов. Для опытной модели были разработаны, в частности, штатив с системой контроля углового положения, устойчивый ртутный горизонт, методика получения показателей вибрационных воздействий. В августе–сентябре 2014 года были проведены лабораторные эксперименты и натурные наблюдения с целью испытания системы телескопа и программного обеспечения в целом. Полученные результаты сопоставлены с результатами экспериментов, направленных на повышение точности нахождения центров изображений звезд с помощью простой оптической системы. Кроме того, было изучено влияние вибраций ртутного зеркала на положение центроида на приборе с зарядовой связью (ПЗС). Результаты экспериментов показали, что эффекты вибрации практически одинаковы для звезд в одном и том же поле зрения и могут быть скорректированы путем вычитания среднего значения; вибрации ртутного зеркала вызывают погрешности в определении центроида до 0,2"; при этом существует сильная корреляция между среднеквадратическим отклонением положения центроида и отношением «сигнал–шум» для изображений звезд. Существует возможность достичь погрешности 0,01" при достаточно высоком показателе отношения «сигнал–шум» и при условии коррекции вибрационных воздействий.

A PZT type telescope for observations of gravity gradient and lunar rotation was developed, and a Bread Board Model (BBM) for ground experiments was completed. Some developments were made for the BBM such as a tripod with attitude control system, a stable mercury pool and a method for collecting the effects of vibrations. Laboratory experiments and field observations were performed from August to September of 2014, in order to check the entire system of the telescope and the software, and the results were compared to the centroid experiments which pursue the best accuracy of determination of the center of star images with a simple optical system. It was also investigated how the vibrations of mercury surface affect the centroid position on Charge Coupled Device (CCD). The results of the experiments showed that the effects of vibrations are almost common to stars in the same view, and they can be corrected by removing mean variation of the stars; and that the vibration of mercury surface can cause errors in centroid as large as 0.2 arcsec; and that there is a strong correlation between the Standard Deviation (SD) of variation of the centroid position and signal to noise ratio (SNR) of star images. It is likely that the accuracy of one (1) milli arcsecond is possible if SNR is high enough and the effects of vibrations are corrected.
