DECIGO
(Deci-hertz Interferometer Gravitational Wave Observatory)
(proposed Japanese space mission to detect gravitational waves)
DECIGO (for
Deci-hertz Interferometer Gravitational Wave Observatory)
is a proposed Japanese space mission
to detect gravitational waves (GWs) by measuring the distance
between three spacecraft using laser interferometry.
It is similar to the ESA LISA proposal, but
on a smaller scale, i.e., with 1000 km arms, designed for a sensitivity
to GWs in the 0.1 to 10 Hz frequency-range, a range not
covered by the current ground gravitational-wave detectors or the LISA proposal.
Recent versions of the DECIGO proposal specify four such triangles of
three arms each, incorporating twelve spacecraft in all.
B-DECIGO is a further-scaled-down version with 100 km arms,
proposed as a pilot mission.
