The Deep Synoptic Array (DSA) is a radio telescope array under construction in Spring Valley, Nevada, USA. The completed array will contain 1,650 steerable 6.15-metre (20 ft 2 in) parabolic antennas that observe the 0.7–2 GHz frequency range, scattered over an area of 19 by 15 kilometres (12 mi × 9 mi). The main goal is a radio survey of the entire sky visible from its site, to search for transient sources. A secondary goal is pulsar timing, to aid in the search for gravitational waves.
The project is managed by the California Institute of Technology (Caltech) as part of their Owens Valley Radio Observatory, with funding provided by Schmidt Sciences. It is expected to be operational in 2029.
