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.
