英文摘要：

For more reality in indoor training astronomic surveying, the real-time equal angles star map simulation was proposed in the paper. The relevant formulas as well as an improved method of circle field searching for searching view-field star were derived. Finally, the program of real-time equal angles star map simulation was developed with Visual C ＋ ＋ , to implement the dynamic star map simulation in any time and station. The precision of the real time star map was given by analyzing the actually measured data.
