Abstract: For the descending parachute，the size of pivot angle is an important indicator of stability.This paper proposes a method of measuring parachute pivot angle by using single GPS.The experimental result indicates this measuring system can obtain the parachute pivot angle value in real time while the parachute is descending，and can reflect the change tendency of the parachute pivot angle more precise.

摘要： 空降过程中降落伞摆角的大小是降落伞稳定性的一项重要性能指标。提出了利用单GPS测量降落伞摆角的方法，并利用该方法进行了实际的测量实验。结果表明：该测量系统能够实时获得降落伞在空中的摆角值，较为精确地反映了降落伞摆角的变化趋势。
