A baseline field test equipment which can rotate automatically is introduced in this paper.Comprehensively integrated with technologies of advanced MEMS inertial navigation,ARM embedding,Wi-Fi wireless transmission,high stability motor drive and high-efficiency power management,this equipment can realize automatic measurement of antenna phase center deviation as well as real time north pointing function.The test results show that the rotation error of the turntable is within 0.1° and the north pointing error is within 1°.This research shows that the automatic measurement system of antenna phase center deviation has advantages of high accuracy,high efficiency and high automation,and has solved the problems of low automation level and the lack of automatic north seeking perplexed tradition measurement methods.Furthermore,the system is integrated into a 35 cm×30 cm×30 cm portable suitcase and weighed less than 10 kg,which makes it easy to use and maintain.
