Embodiment Construction

[0024] Below in conjunction with accompanying drawing, further elaborate the present invention.

[0025] Such as Figure 1-5 As shown, the sextant astronomy simulator of the present invention includes a moving mirror, a fixed mirror, a telescope, a bracket, an inclination sensor, an axis angle encoder, an embedded computer and a display module. Among them, the inclination sensor adopts a three-axis electronic compass, and one of the axes of the three-axis electronic compass is consistent with the optical axis of the telescope, which is used to measure the three-axis attitude of the simulator's azimuth, roll, and pitch, and to determine the direct field of view The spatial orientation of the center of the field of view and its rotation angle.

[0026] The three-axis electronic compass is fixed on the sextant bracket body, and one of the axes is consistent with the optical axis of the telescope, so that it can be used to measure the three-axis attitude of the simulator's azimut...

Abstract

Provided is a control method of a sextant astrogeodesy simulator. The method comprises the following steps: step 1, initialing equipment, and initializing a calculating unit and a peripheral device thereof; and step 2, entering while cycling, waiting for various interruptions, and entering corresponding interruption service programs according to the different interruptions; and a timer being interrupted, a triaxial compass connection port being interrupted, a GPS module connection port being interrupted, and a display screen dynamically displaying simulated sky images in real time. Through the attitude control of a sextant, and by accurately adjusting the mutual position relation between a perpendicular incident image and a reflection image, the height of a heavenly body is measured, and the purpose of training astrogeodesy skills is realized.

Description

technical field [0001] The invention relates to a virtual reality simulator, in particular to a control method of a sextant astronomical simulator. Background technique [0002] The current observation training of celestial body height mainly adopts the mode of actual observation at sea. In the weather with good visibility, after the ship sails to a certain sea area, the actual observation of the height of the celestial body can be carried out. The trainees firstly carry out the preparatory work before the observation, such as the inspection and regulation of the sextant, the measurement of the index difference, the identification of the stars, etc., and then observe according to the observation method of the height of the celestial body. The real height of celestial body observation is obtained through the observation by the instructor or by using the PDA calculation software, which can continuously calculate the height of the celestial body at that moment according to the...
