Troubleshooting Triggering Issues

Prior to operating the camera there are critical steps that need to be followed. They are outlined in the MicaSense Sensor checklist for operation.

Once you have connected to your MicaSense sensor, setting your camera up to trigger is a simple process. However, there are many factors that may lead to your camera not triggering during flight. This article will offer possible causes and troubleshooting tips that may help determine and solve the issue. 

Triggering issues can be broken down into three scenarios: No images were captured on the SD card, the camera stopped capturing mid-flight, and inconsistent triggering leading to data gaps. We separate these scenarios below and outline possible causes and ways to avoid and/or troubleshoot them. 

1. No Images Captured

  • Check cable connections, are they secure?
  • Was the triggering method set up via the WiFi interface before flying?
    • If using overlap mode, double check your target altitude.
      • Camera starts capturing 50 m below target altitude and stops capturing if the altitude goes 50 m below the target altitude.
      • If using Atlas flight, the camera is automatically set in Overlap Mode.
    • If flying in timer mode, test your power supply and make sure it provides the necessary voltage even under load.
    • External trigger
      • Is the trigger cable connected to triggering source?
  • Did the camera have adequate GPS reception prior to the flight (shown on the WiFi interface)? 

2. Camera Stopped Capturing Mid-Flight

  • Could be a power issue
    • Test your power supply under load: Power the camera on the ground (with your standard power setup), put the camera in timer mode, 0.25s capture interval, and see if the camera can continuously capture
    • Test an alternative power source
  • Ensure you have ample storage available prior to flying
    • RedEdge-M storage limit: 32 GB
    • Altum storage limit: dependent upon the storage device used (USB 3.0 compatible devices)

3. Inconsistent Capturing (gaps in data)

Post-Flight Check

To ensure that you captured the expected amount of captures during your flight, check the coverage estimator after your flight. This can help you to determine whether your flight was successful or not prior to heading out of the field.

 

If you are still experiencing triggering issues, please send a description of the issues, as well as log files (paramlog.dat and diag.dat) from an affected flight to support@micasense.com.
