After analyzing the advantages and disadvantages of photoelectric tracking system withhorizontal gimbal and X-Y double-axis gimbal
a vertex tracking method based on airborne photoelectricequipmenthas been presented. The method
which combines advantages of horizontal gimbal and X-Y double-axis gimbal
can effectively track target in the blind area. experiments show that the tracking method is simple
tracking accuracy is 3
meet the technical requirements. 2011 IEEE.

It is essential to analyze the gimbal displacement errors for a seeker due to the importance for cueing of targets and tracking for the final approach. Otherwise
for a seeker electro-driven with a concentric glass dome
the large errors will decrease the picking
pointing
and tracking precision rooted from the displacement errors existing between the rotation center of the optical system and the gimbal. And the gimbaled camera system displacement errors are never eliminated but reduced due to the geometric errors consists of geometric tolerances of gimbal structure
manufacture
installation and vibration coming from working environment. In this paper
the gimbal displacement errors in an electro-optically stabilized platform resulting from geometric errors and environment errors were analyzed and shown in detail. The mathematical modal of the gimbal displacement errors created based on multi-body dynamics demonstrated the connection between the gimbal displacement errors and the stabilized platform. Taking a visible light image seeker as a case
the diameter is 120mm
and the geometric tolerances came from the values of primary design and the vibration data came from the environmental vibration test on the pitch-yaw seeker
and at the same time
the errors resulting from installation were considered too. Based on calculating
the maximum gimbal displacement error will reach to 0.2mm for pitching angle smaller than 40 and yawing angle smaller than 60. However
the critical parts have been found out according to the probability theory and the reliability analysis successfully used in the paper
and finally
the maximum gimbal displacement error reduced to 0.1mm
which is acceptable corresponding to the picking
pointing and tracking precision for an optical imaging seeker. 2010 Copyright SPIE - The International Society for Optical Engineering.
