Tesat第二代LCT的粗瞄準(zhǔn)機(jī)構(gòu) (CPA)（實(shí)際上是一個(gè)配備相干接收器和發(fā)射器硬件的望遠(yuǎn)鏡）需要一種新型圓光柵。雷尼紹與Tesat合作開發(fā)了太空級(jí)光柵，該產(chǎn)品的許多核心技術(shù)均來自雷尼紹成熟可靠的TONiC?光柵系列產(chǎn)品。它可以承受-40°C至+80°C的工作溫度、太陽/宇宙射線的沖擊，以及火箭發(fā)射所要求的高機(jī)械載荷?？馆椛浼訌?qiáng)技術(shù)結(jié)合雷尼紹可靠的光學(xué)檢測原理，使得該光柵可在地球同步軌道 (GEO) 環(huán)境下提供長達(dá)15年的服務(wù)。
雷尼紹和Tesat合作開發(fā)的*的太空級(jí)光柵安裝在CPA的兩個(gè)回轉(zhuǎn)軸上，并將集成到包括哨兵系列衛(wèi)星 (Sentinels)、歐洲數(shù)據(jù)中繼衛(wèi)星EDRS-A和EDRS-C在內(nèi)的許多未來空間站的LCT上。該光柵系統(tǒng)包括一個(gè)柱面上刻有刻度的不銹鋼圓環(huán)和一個(gè)特別改裝的讀數(shù)頭。INTRAC?參考零位直接嵌入增量通道，其排列形式使任意兩個(gè)參考零位之間的距離都各不相同。這意味著只需稍稍旋轉(zhuǎn)光柵便可確定位置。該太空級(jí)光柵的另一個(gè)優(yōu)勢(shì)是圓環(huán)與靜態(tài)讀數(shù)頭之間沒有接觸，因此不會(huì)產(chǎn)生摩擦，從而避免滯后誤差以及潛在的磨損，并且也不需要潤滑。該系統(tǒng)的分辨率小于0.5 μrad，短距離誤差<0.5 μrad ，且長距離誤差<5 μrad。
