| description | The invention relates to a navigation measurement combination calibration compensation method and a test board, and belongs to the technical field of navigation measurement. The method comprises the following steps: respectively carrying out a calibration experiment on a navigation measurement combination at three different temperature points, and measuring the number of pulses output by each measurement channel of the navigation measurement combination at each temperature point; the number of pulses output by each measurement channel at each temperature point is substituted into the error model of each measurement channel, and the error amount of each measurement channel at each temperature point is solved; performing quadratic term function fitting on the error amount of each measurement channel under each temperature point and the temperature of each temperature point to solve a compensation coefficient of each measurement channel; and realizing calibration compensation at any temperature according to the |
