DAQ-A
The DAQ-A is an aerodynamic PPK data logger containing GNSS (GPS) and IMU position sensors, with a user-accessible micro SD card for saving the data log. There is a USB port for power input, an RGB LED status button and two Survey3 camera connection ports.
Main Features:
-
The DAQ-A continuously saves the sensor data from the GNSS and IMU, as well as the PWM (camera trigger) and EXP (camera exposure) events.
-
The removable micro SD memory card stores data log files and the user-editable DAQ configuration file. Log file is used in MAPIR software to improve the image geolocation information (PPK), as well as adjust the calibration over time.
-
Camera trigger signals are sent with each DAQ-A button press, or at set time intervals. The user can easily adjust the triggering rate interval by editing the configuration text file on the memory card.
-
Support for 2 separate Survey3 camera exposure logging. This allows for more accurate image geolocation metadata updates during post processing (PPK).
-
Daylight readable RGB LED button shows system status. LED brightness is adjustable and disableable. Button triggers cameras and turns logging on/off.
-
DAQ-A can be conveniently powered by 1 or 2 Survey3 cameras, or using the side USB port.
-
Automatically syncs connected Survey3 camera system clock time (RTC). Make sure cameras are set to time zone GMT-0.
-
Easy firmware updates using firmware file on the SD card.
Mounting Options:
Designed into the bottom of the DAQ-A are rails that mate with our various DAQ-A mounting plates. Simply pull the tab on the plate down and slide the DAQ-A into the mount. We offer mounts that contain multiple through-holes, a 1/4-20 threaded tripod hole, and drone specific models (DJI Mavic 3, etc). You can also use double-sided tape (not included) to attach to any surface.
Power Options:
You can power the DAQ-A using the side USB port OR the rear Survey3 camera connection ports. If using short 10" cables you can use a single Survey3 camera to power the DAQ-A. If you use longer cables you will need 2 Survey3 cameras, or USB power. Never apply power to BOTH the USB and camera ports. Runtimes below are for continuous RAW image capture (every 3s).
