The declination axis is set on the two ends of the inner frame in east-west direction.Using a hand-operated screw adjusting mechanism,the angle between the receive plane and the right ascension axis is controlled to be equivalent to the latitude every day.Tracking time is limited from 7 am to 5 pm,the concentrating area is 10 m~2,and the driver power is only 12 W.
自行设计了双轴调节太阳跟踪装置，其特征在于通过南北向布置的赤经轴按时钟角速度转动，同步带动一个挂在赤经轴两端的内框转动，在内框的东西框边的赤纬轴上安装有接收面支架，由手动螺旋调节机构调节接收面支架的平面与赤经转轴的夹角每天等于赤纬度。

The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO－LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO－LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km . 4 The RAAN of TS and RS has a great influence on the LEO－LEO occultation number, but has little influence on occultation distribution.
结果指出：1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距；而这些参数对一年掩星事件的经度分布影响都不大；2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大，两卫星倾角接近互补时掩星事件最多，两颗LEO卫星中与90°相差较大的倾角决定了LEO－LEO掩星事件的纬度分布范围；3发射卫星和接收卫星处于同一轨道高度时，LEO－LEO掩星事件数取得极大值，发射卫星和接收卫星都采用600 km的轨道高度，一年LEO－LEO掩星事件数最多；4 发射卫星和接收卫星升交点赤经的相互关系对LEO－LEO掩星事件数量影响很大，发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多，RAAN对掩星事件纬度和经度分布影响不大；5近地点角距对掩星事件数量和分布影响都不大。

right ascension：赤经
也没有创用专门的术语.称"赤纬"(declination)为"沿着过极点的大圆与赤道的距离"."赤经"(right ascension)的表达也很奇特,如说成"沿着平行的小圆占据某某星座若干度".他将平行于赤道的小圆划分为12等分,
