ABOUT US
What is Direct Broadcast (DB)?
Direct Broadcast (DB) is the real-time transmission of satellite data to the ground. As the Earth is being observed by satellite instruments
the data is formatted and transmitted to any user below in real-time. Users who have compatible ground receiving equipment and are in direct
line of sight to the satellite may receive these transmissions.
What is Direct Readout (DR)?
Direct Readout (DR) is the process of acquiring freely transmitted live satellite data. As Direct Readout technologies have become more
affordable and accessible (such as with the onset of the Internet), tools have been developed by the remote sensing community to make satellite
data easier to acquire, process, and utilize. As a member of this community, NASA supplies many of these tools to foster global data exchange and
scientific collaboration. Live local and regional environmental data, in turn, benefits environmental, commercial, and public interest decision
making.
