NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
The use of real-time aircraft data by ground systems to plot 4-dimensional trajectories (lateral and vertical navigation, ground speed and longitudinal navigation), and perform conformance management, will shift air traffic operations from minute-by-minute tactical control, to more predictable and planned strategic traffic management.
The app began operations in 2008 and ran on government-provided weather and radar data for its first decade. In 2019, ACME launched personal satellites to improve predictions of ongoing weather. The app received funding to improve its radar and imaging from the Federal Communications Commission (FCC), National Oceanic and Atmospheric ...

The information from the signal is sent to an Air Traffic Control tower, or a Radar Approach Control (RAPCON) with a digital tag that describes the location, heading, and speed at which the aircraft is moving. The overall operation of the ASR-11 is similar to that of the ASR-9, with relatively few differences between the two radar systems.
A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data from several different ...
NextGen systems can also increase controller and pilot productivity, such as with Data Communications. [ 24 ] NextGen improvements are estimated to save 2.8 billion gallons of fuel through 2030 [ 24 ] and reduce carbon emissions by more than 650 million metric tons from 2020 to 2040. [ 25 ]
The FAA provides air traffic control services, handling about 55,000 flights per day, and serving over 700 million passengers a year. NextGen Through Multi-Agency Involvement As part of the NextGen effort, the FAA is working closely with several government agencies that make up the Joint Planning and Development Office. JPDO includes the U.S ...
