The QHY-GPSBOX is a compact camera accessory that provides high-precision GPS hardware time scales allowing some QHYCCD cameras to obtain accurate time information of the camera's exposure time.  In addition, this information is returned to the camera internally and added to the image data after the start of one frame of the image.  GPS timing information and image information are therefore completely consistent.  No confusion is created due to transmission, buffering or other reasons. It is very convenient to use and read.
