美國海軍研究實驗室航天器工程部的空間機器人學研究所最近獲取了固定的基於花崗岩的 75,000 lb 重力抵銷表唯一平板 (GOT)。

精確度磨刀了對在內 +/-0.0018 在其表面,重力抵銷表間的英寸容差 (顯示)

相當數量的航空乘在地球上的航天器要求 『浮動』這個對象為了仿造存在於在全方位複製品的空間的物理的經典力學。 憑無磨擦,準確,大表面,研究員可能改善複製品慣性的作用對在空間的綜合對象。

當前,特別地被設計的預先配置的耦合裝置和聯接結構啟用達到獲取或控制在軌道的航天器。 基於在地球上的幾種航天器配置,研究員需要首先展示錯誤的最小的費率以價格合理和高效率的方法。 這將導致高效獲取和為服務 『沒有任何常規聯結結構的自由飛行』軌道的航天器。

這个 20x15 ft, 1.5 ft 厚實的單件花崗岩是在 +/- 0.0018在其表面間的艙內甲板內并且以精確度花崗岩為特色。 並且,它遵照所有聯邦 『AAA』說明。 NRL 研究員將使用這個精確度獲得準確地模擬對象的無磨擦的行動在空間的和推測衛星在軌道的為服務和入塢機制動力。 此結構是重要的由於生長生成費用。 新的軌道的航天器包括可以通過更新或修理已經存在於環地軌道的資產補償。

450 立方英尺, 37.5 T 獲得的平板從 Raymond 花崗岩獵物,克洛維,加利福尼亞被提取了。 認為這個世界的最大,唯一平板,精確度與允差上限的花崗岩表,工程師能模擬全方位衛星航天器服務有高結構上的靈活性的到唯一,史無前例的準確度。
