NOAA engineers have created a heads-up navigation display for pilots for coastal imagery acquisition, “ONav.” The system is built on the Linux operating system (Debian) and utilizes a number of open-source tools and data sources. The system combines a real-time Global Positioning System (GPS) and Inertial Measurement Unit (IMU) stream along with image collection metadata from the on-board cameras to generate vector overlays the pilots can use to easily navigate, track progress, and ensure full coverage of the survey area. This technique has vastly improved the efficiency with which we can collect imagery.
Benefits of the ONav System:
- Portable, low-cost
- Web browser based; no software installation required
- Can be deployed worldwide
- Enables on-the-fly mission planning
- More efficient mid-flight error corrections
The GeoPixel™ imaging system developed by NOAA is designed to be used with the ONav system. GeoPixel™ displays a grid of Ground Control Points (GCP) over the visible image. GeoPixel™ tracks the movement of the cursor over the image to display the calculated position in three dimensional space. An example of images can be viewed at: http://geodesy.noaa.gov/storm_archive/coastal/viewer/index.html
Benefits of the GeoPixel™ System:
- Real-time high definition imaging
- Precise longitude and latitude (mouse over images)
- Multiple commercial applications including:
- Search and rescue
- Disaster relief
NOAA is seeking a U.S.-based licensee to package and sell this technology for various aeronautical applications worldwide.
