The method does not depend on strict local parameters and precise instruments, while the observational principle is relatively simple. An experimental observation was carried out with a simple telescope with large field of view at Xinglong station of NAOC at the end of 2007. The atmospheric refraction from the zenith distance of 44.8 degree to 87.5 degree is gotten by the differential method, which proves the feasibility of the method tentatively.
该方法不依赖于严格的地方参数和复杂精密的观测仪器,并且观测原理相对简单。2007年底,利用一台简易的大视场望远镜在兴隆观测站进行了试验观测,根据较差方法实测得到真天顶距44.8°至87.5°的大气折射值,初步证明了大气折射较差测量方法的可行性。
