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.
The QHY-GPSBOX has a built-in GNSS module and can currently provide both pure GPS operation and GPS/Beidou dual-mode operation. The latter can be set to work in GPS mode or Beidou mode through software. The GPSBOX also contains a local 10MHz voltage controlled crystal oscillator (VCXO) that provides an internal 0.1us resolution timing clock. At the same time, the timing clock is reset by the PPS model of the GNSS module. Therefore, the clock and the GNSS system’s second start time are strictly aligned, and the error is within a range of 20ns to 100ns.
QHY-GPSBOX and camera are connected by 6-pin aviation plug. Contains the following signals:
