Description

The Institute for Telecommunication Sciences (ITS) provides research and development support for theNational Telecommunications and Information Administration (NTIA) by performing basic research inradio science that provides the technical foundation for NTIA’s policy development and spectrummanagement activities, as well as solves telecommunications challenges for other Federal agencies, stateand local Governments, private corporations and associations, and international organizations. ITS has a troposcatter measurement system and is deployed for long durations and is required to record very sensitive fluctuations in received signal power resultant from changes in the atmospheric channel between the transmitter and receiver. The influence of the atmosphere and weather patterns is very important to this work. Local weather stations at the transmit, receive and along the path to record relevant parameters such as wind speed, humidity, temperature, etc are critical for the success of this effort.
