(planned radio telescope array as a follow-on to ALMA and the Jansky VLA)
The Next Generation Very Large Array (ngVLA) is a 1-100
GHz radio telescope array/interferometer beginning development,
to be a step up from the Atacama Large Millimeter Array (ALMA) and the Very Large Array (VLA), with ten times the
collection area of either and support for a range of baselines
up to VLBI distances. Plans call for a main array and a short-baseline
array in New Mexico, regional sites supporting up to 300-km baselines,
and a few very-distant sites for thousands of km. Designing began
around 2021, with the intent to prototype in the early 2020s, begin
construction in 2025, begin partial operation in 2029, and begin
full operation in 2035.
