Embodiment
As Fig. 1, the utility model comprises development board, mechanical transmission unit, power module, and development board adopts HMI-STM32, is provided with processor 1, TFT LCDs 2 in the development board, and processor 1 is connected with touch display screen 2; Mechanical transmission unit comprises: base 7, be installed with second motor 5 on the base 7, the output shaft of second motor 5 is connected with platform 8, gyroscope 6 is fixedly mounted on the platform 8, and the X-direction of gyroscope 6 is provided with first motor 4, and X-axis is parallel with platform 8, first motor 4 is connected with camera 3, camera 3 is positioned on the Z-direction of gyroscope 6, and the Y-axis of gyroscope 6 is parallel with platform 8, and the output terminal that the X of gyroscope 6, Y, Z are three is connected with processor 1 input end respectively; Platform 8 one sides are equipped with weight 11, and on the base 7 of platform 8 same side index dial 12 are housed, and base 7 is provided with leveling nut 13; Processor 1 output terminal is connected with first motor 4, second motor 5 respectively, be provided with battery 9, DC-DC electric pressure converter 10 in the power module, battery 9 is connected with development board, camera 3, first motor 4, second motor 5, gyroscope 6 respectively by DC-DC electric pressure converter 10.
Gyroscope 6, the first motors, 4, the second motors 5 of the utility model device and the data line and the power lead of camera 3 all place in the base 7, and gyroscope 6 adopts mechanical gyroscope or electronic gyroscope (electronic compass).
Fig. 3 and shown in Figure 4 be relation between subsolar point, elevation angle, position angle and the tellurian longitude and latitude of current particular moment.Under the situation that date and time is determined, solar energy impinges arrives locally on earth, can both obtain the elevation angle of the sun and the position angle of the sun, the elevation angle of the sun one belt interior all be identical, subsolar point is that the sun all is identical in these regional elevation angles on the circle at center as shown in Figure 1.That line segment AO represents is position angle (is 0 degree benchmark with positive north) the line segment AB and round M, N, the F point of giving of the sun, (on the current longitude and latitude) has the combination of unique sun altitude and solar azimuth on these aspects, so just can determine local longitude and latitude by detecting elevation angle and position angle.Fig. 2 represents is to have different elevation angles the same azimuthal the time, and the position angle of some B, C and some D, E is to differ 180 degree.The longitude and latitude computing formula is as follows:
JD=(SJ+12-XS-FZ/60-E/60-M/3600)×15 (3)
