本文针对星间链路建链过程中卫星相对运动特性，研究基于建链规划表和卫星星历计算卫星天线指向角度的算法，编写了建链指向软件，根据地面站上注的建链规划表信息以及星载计算机给出的时间、卫星姿态等信息，实时计算波束指向所需的方位和俯仰角信息。通过实际数据解算，将软件计算结果与 STK 软件仿真结果进行比对，验证结果表明，方位角和俯仰角计算误差在10-4度量级，验证了算法的正确性和可靠性。

In view of the dynamic characteristics of the satellite movement between building inter-satellite link, the article studiesthearithmetic of calculating satellite antenna pointing angle based on clock built chain and satellite ephemeris. It also writessoftware for building inter-satellite link. It calculates the azimuth and pitching angle of the beam pointing timely using the clock built chain, which is uploaded by ground station, and the information of time the posture of satellite and so on which is given by on-board computer. According to calculating the actual data and comparing the result with STK simulating result, it indicates that the pitching and azimuth angle error is in 10-4 degree scale. It verifies the correctness and reliability of the arithmetic.
