我们提出了下一代过境调查，这是在英国建造的原型望远镜在2008/2009年和2010年在加那利群岛的拉帕尔马测试。原型系统的目标有几个方面：确定NGTS类系统中的系统噪声水平;证明我们可以在宽视场的凌日时间尺度上进行（亚）毫米级的测光;表明有可能探测凌日的超级地球和海王星大小的系外行星，并证明拟议的行星调查的技术可行性。我们对系统进行了大约100个晚上的测试，并达到了上述每个目标。在原型设计阶段突出了几个需要改进的关键领域。这些问题随后在最近在智利Cerro Paranal的ESO投入使用的最终NGTS设施中得到解决。
We present the prototype telescope for the Next Generation Transit Survey, which was built in the UK in 2008/2009 and tested on La Palma in the Canary Islands in 2010. The goals for the prototype system were severalfold: to determine the level of systematic noise in an NGTS-like system; demonstrate that we can perform photometry at the (sub) millimagnitude level on transit timescales across a wide-field; show that it is possible to detect transiting super-Earth and Neptune-sized exoplanets and prove the technical feasibility of the proposed planet survey. We tested the system for around 100 nights and met each of the goals above. Several key areas for improvement were highlighted during the prototyping phase. They have been subsequently addressed in the final NGTS facility, which was recently commissioned at ESO Cerro Paranal, Chile.
