摘　　要：ＣＳＡＯ和ＶＳＮＩＩＦＴＲＩ１９９３年秋正式签订了将陕台ＰＨＡＩ搬去伊尔库次克进行国际合作观测、研究的协议．为了执行此项合作协议，首先对仪器进行了改造，使其能工作在Ｚ＝４５°的等高圈上；同时编制了适合于伊尔库次克纬度和新天顶距的观测纲要，全纲要共包括１２个星组，含６６８星次。其中ＦＫＳ基本星为３２４星次；ＦＫＳ扩展星和补编星为３４４星次；两次过等高圈的有２０３颗星，一次过等高圈的有２６２颗星，极限星等为９．５ｍ．恒星的赤纬分布在＋８．９°～＋７４．４°之间，赤纬跨度达６５．５°，在此赤纬带内可以消除赤其测定中的盲区．SAO and VS NIIFTRI ho reached an agreement on moving the PHA I to Irkutsk in order to eliminate the blind cone in the determination of star declination.The PHA I has ben revised and could work on the almucantar with zenith distance of 45°The new observing program consisting of 668 star transits (among them 324 are FK5 basic stars, 344 FK5 extention and supplement)with limiting magnitude of 9. 5 was made,among which 203 stars are double transits,262 stars single transit. The declination of the stars cover a zone from +8.4°to +74. 4°with a large span of 65. 5°,over which the blind cone of declination determination could be eliminated just with PHA I observations.The results of one month testing observation in Irkutsk has shown that both PHA I and observing site are quite good for star catalogue, Earth rotation and plumb line measurements.
