摘　　要：面对日益繁重特别是特殊环境(如海上测控)的标校任务需求,提出并实现了一种便捷、可动态标校的微小型信标球,其电子系统由锂电池、双频GPS,UCB测控应答机、综合电子模块等组成。双频GPS获取信标球原始测量数据和自定位结果;UCB测控应答机下传GPS数据,同时可作C波段地面测控设备合作目标,用于地面测控设备雷达和UCB设备相互校准。信标球重1 kg,功耗10 W,体积为25 cm×25 cm×10 cm,工作时长16 h,定位精度优于1 m,并在某基地成功进行了放飞试验。Aiming at calibration mission requirement for calibration in special environment,such as maritime tracking and control,present a convenient and dynamic calibration micro beacon ball,which contains a lithium battery,a double frequency global positioning system（ GPS）,a UCB transponder and an integrated electronic module,etc. Double frequency GPS provides raw measurement data and self-positioning results; UCB transponder can transfer data to the ground station and can be used as a C-band calibration cooperative target,which is used for intercalibration of ground measurement and control equipment radar and UCB device. The weight of the beacon ball is 1 kg,the power consumption is 10 W,the volume is 25 cm × 25 cm × 10 cm,working hours is as long as 16 h,the positioning precision is better than 1m,and flying test at a base is successfully conducted.
