QHY174 (GPS) Cooled Small Size CMOS Camera

QHY174-GPS New Horizon Science Project

More than 20 QHY174-GPS cameras were selected by NASA's New Horizon Team for imaging an occultation by MU69.  The data will be using for the New Horizon MU69 flyby in 2019.  The imaging mission was a success and the MU69 occultation event was record by five team members.

"This effort, spanning six months, three spacecraft, 24 portable ground-based telescopes, and NASA's SOFIA airborne observatory was the most challenging stellar occultation in the history of astronomy, but we did it!" said"

Alan Stern, New Horizons principal investigator from SwRI.




The QHY174-GPS camera is the same as the QHY 174 but with the addition of an optional GPS based precision time and location function, useful for imaging occultations, eclipses, meteors, and other scientific imaging requiring a highly precise recording of the time and location of the observation on every frame. The QHY174-GPS has dual stage TE cooling to -45C below ambient with full antimoisture control.

The QHY174 also has an anti-amp glow function. It can reduce the IMX174 sensor's amplifier glow significantly in long exposures. The IMX174 (GPS) sensor has a global shutter and is capable of high frame rates, both ideal features for a time-domain imaging camera. The QHY174M-GPS will record the global shutter exposure starting and ending time with microsecond precision. Two QHY174 cameras, for example, each located anywhere in the world, can have the same time base, accurate to microseconds. In order to guarantee the starting and ending time of the exposure, the QHY174 has a built-in LED pulse calibration circuit precise to 1 microsecond.

The QHY174 camera is designed to be an excellent planetary, lunar, solar and meteor capture video camera. With a 50mm F1.4 lens it will record mag 8 to mag 9 stars in live video recording at 30FPS (33ms exposure), several magnitudes fainter than can typically be seen with the naked eye.


Master mode: In Master Mode, the camera is free running and the internal 10MHz GPS synced clock will measure and record the shutter's opening and closing time. Slave mode: In Slave Mode you can input a target start time and the interval period for two frames. For example: You want three cameras in different locations (maybe thousands of kilometers apart) to start an exposure at 2016.3.9.UTC 14:00:00.000000 and then to continue with exposures at the interval time of 0.100000 sec. After you input these values, all the three cameras will wait until this time and then simultaneously start video recording. The time stamp and other GPS information is embedded into the image. The software decodes it in real time and displays the information on left. Since the data is embedded, it will never be lost so long as you keep the original image.

Dual-stage TE cooling reduces the sensor temperature to -40C or more below ambient and temperature regulation maintains a constant temperature set point. Due to the efficient TE cooling, single exposure times up to 30 minutes are possible on most models, making them suitable for deep space imaging of dim objects as well as brighter objects and planets.
