A Dynamic Evaluation Method on Photoelectricity Deviation of Shipborne Measuring Equipments

Based on current photoelectricity deviation calibration methods, a new method on shipborne measuring equipments photoelectricity deviation calculation and dynamic valuation is put forward, aiming at solving the problem that is difficult to choose the optimum value among the inconsistent results of current various photoelectricity deviation calibration methods in the maritime complex dynamic environment. Taking the advantage of the precise character of theoretical elements ratiocinated from the information of precision orbits and combining the data from the shipborne measuring equipments, equations are set up to compute the photoelectricity deviation, which are just used as authentic true value to carry out multiattribute selection from those current various methods. The results show that this method can overcome the problem to make choice of the reasonable one from those inconsitently direct calibration parameters.
