Global Shutter
━━━━

High Speed Capture
Undistorted Imaging

The QHY174GPS camera uses the 1/1.2-inch SONY IMX174 CMOS sensor with global shutter, 5.86um pixels,138FPS@1920*1200, high QE of 78%, and low read noise of 3-5e-. Unlike a rolling shutter, a global shutter guarantees that the exposure time for the whole image area is uniform, beginning and ending at exactly the same time. This type of shutter is ideal for high precision time-domain applications.

QHY174GPS Time Domain Imager
━━━━

Built-in GPS
1us High Timestamp

The QHY174GPS has a unique built-in GPS module that can sync with the atomic clock signals received from GPS satellites. The QHY174GPS can record the start and end of exposure time with 1us precision anywhere on earth. The QHY174GPS was selected by the NASA New Horizons Team to successfully captured the MU69 occultation in the Summer of 2017.

TEC cooled
━━━━

2-stage TEC
-45C below ambient

The QHY174GPS uses 2-stage TEC cooling to significantly reduce dark current.

Amplifer Glow Reduction
━━━━

Unique Technology
High Reduction Ratio

The IMX174 sensor normally has significant amplifier glow which will affect the entire image area in exposures of any significant length. However, QHYCCD has successfully incorporated our unique amplifier glow reduction technology into the design of the QHY174GPS camera to yield excellent results with this sensor.

Multiple Scientific Applications
━━━━

Free Running Mode
Multi-Site Sync Mode

The QHY174GPS is the best camera for the high precision time-based scientific projects. It includes two working modes. In Free Running Mode, the hardware records the GPS time and internal 1us calibrated time into the image header of every frame. In Multi-Site Sync Mode, users can control multiple cameras that are thousands of miles apart so that they start exposures at exactly the same time to the microsecond.

Occultation

The QHY174GPS is the ideal camera for cooperative multi-site imaging of asteroid occultations.

Meteor

Two or three QHY174GPS cameras equipped with wide-angle lenses or all sky lenses can be used to determine the 3D position, speed and the geometric position of meteors.

Exoplanet

The QHY174GPS is ideal for multi-site, high precision timing of exoplanet light curve measurements.
