摘　　要：电冰雾喷淋试验需要在-30℃~0℃的条件下令直升机在空中保持悬停状态,试飞员要将飞机控制在30×30 m的最佳的喷淋范围内,其间由于冰雾状况其处于视觉不佳状态。针对这一实际情况,开发一款适用于小型场地的便携式轨迹跟踪定位系统。利用北斗系统(BDS),采用伪距测量与载波相位测量相结合的方式,实现直升机悬停过程中的轨迹跟踪定位。The ice mist spray test requires the helicopter to remain hovering in the air under conditions of-30℃~0℃.The test pilot needs to control the aircraft within the optimal spray range of 30×30 m,during which it is visually impaired due to the ice mist condition.It develops a portable trajectory tracking and positioning system suitable for small venues to address this practical situation.Using the Beidou system(BDS),a combination of pseudorange measurement and carrier phase measurement is employed to achieve trajectory tracking and positioning during helicopter hovering.
