Deci-hertz Interferometer Gravitational wave Observatory

The DECi-hertz Interferometer Gravitational wave Observatory (or DECIGO) is a proposed Japanese space-based gravitational wave observatory. The laser interferometric gravitational wave detector is designed to be most sensitive in the frequency band between 0.1 and 10 Hz, filling in the gap between the sensitive bands of LIGO and LISA. Its precursor mission, B-DECIGO, is currently planned for launch in the 2030s, with DECIGO launching at some time afterward.
