1983 GPS and Its Components: Limited Application of Use

  • A Limited Number of Satellites
  • Analysis Centers
  • GPS Receivers
  • NGS began using GPS in 1983. This Macrometer V1000 is the first GPS receiver owned by NOAA.
today s gps and components three major changes

noaa leads igs analysis centers
NOAA Leads IGS Analysis Centers
  • NOAA’s National Geodetic Survey was selected to coordinate International GNSS Service (IGS) analyses for the next four years.
  • NGS was selected out of 10 other IGS analysis centers to perform the main product combination and quality control operations.
  • Products consist of satellite orbits, clocks, and associated Earth orientation parameters.

navigation positioning and docking of noaa s fleet
Navigation, Positioning, and Docking of NOAA’s Fleet
  • GNSS enabled digital displays provide all-weather navigation, positioning, and docking.
  • GNSS provides the foundation for safe operations during adverse weather, such as fog and blinding storms.
  • GNSS real-time navigation and water-level data prevents groundings and collisions with bridges.
gnss helps prevent the destruction of marine environments caused by industry
GNSS Helps Prevent the Destruction of Marine Environments Caused by Industry
  • 98-percent of nation’s tonnage in international commerce moves by sea.
  • Without accurate geodetic information, nautical charts would be riddled errors, accidents, groundings, and spills of hazardous cargo would increase.

gnss and noaa s emergency response
GNSS and NOAA’s Emergency Response
  • GNSS allows NOAA to track the current location and movement of oil spills, which allows for positioning of defensive equipment to protect marine environments.
  • Environmental sensitivity maps and spill-response models help cleanup managers identify the most vulnerable ecological areas near a spill and predict how the spill will respond to weather, current, and tide conditions.
  • GNSS guides emergency responders to disaster areas quickly, accurately, and efficiently.
gnss and weather forecasting
GNSS and Weather Forecasting
  • GNSS is a reliable, low-cost technology for measuring water vapor, which is essential for predicting storms.
gnss guides marine resources in estuarine and coastal wetlands
GNSS Guides Marine Resources in Estuarine and Coastal Wetlands
  • Coastal zone managers are able to make more informed decisions about fisheries programs, stock assessments, algal blooms, and other issues affecting the health and vitality of coastal ecosystems.
gnss and the shallow water positioning system swaps
GNSS and the Shallow Water Positioning System (SWAPS)

SWAPS provides research opportunities to quantify patterns of damage and recovery on shallow coastal habitats, including:

  • The potential for surveying large areas rapidly without the need to deploy divers,
  • The ability to return to specific locations within damaged areas without establishing perimeter tags or markers, and
  • The ability to survey an area remotely without specialized field personnel.

increased efficiency and better environmental stewardship with precision agriculture
Increased Efficiency and Better Environmental Stewardship with Precision Agriculture
  • Onboard computers in farm equipment can regulate the precise mix of chemicals for every square foot based on known soil qualities and GNSS positioning, effectively reducing the amount of fertilizer and pesticides used.
  • Harmful farm runoff, which contaminates watersheds, decreases as position accuracy increases.
  • Crop output can increase as GNSS guided robotic farm equipment can be used 24-7.

gnss and digital elevation maps dems
GNSS and Digital Elevation Maps (DEMs)
  • With the help of GNSS, more accurate DEMs can be produced to support Community Resiliency efforts by better detecting local relative sea-level rise and water-levels in flood prone areas.
  • DEMs in coastal ecosystems provide a better understanding of a wetland’s ability to serve as a storm-surge buffer.
