[1] The network serves multiple purposes, including the provision of operation data for use in space weather prediction,[2] and the study of solar internal structure and dynamics using helioseismology.

[3] GONG was constructed to provide observations for helioseismology, which aims to understand the solar interior by analyzing the sound waves that are trapped in it.

To replace it, NSO is proposing to design and build a next-generation Ground-based solar Observing Network, provisionally named ngGONG.

[4] In April 2023, NOAA Science Advisory Board reported on the importance of GONG and its successor data source for space weather operations.

The Decadal Survey for Solar and Space Physics (Heliophysics) 2024–2033 by the National Academies of Sciences, Engineering, and Medicine[6] recommends ngGONG as NSF's top priority for its Major Research Equipment and Facilities Construction (MREFC) Program.
