HALCA (Highly Advanced Laboratory for Communications and Astronomy), nke a makwaara maka aha ọrụ ya bụ VSOP (VLBI Space Observatory Programme), aha koodu MUSES-B (maka nke abụọ nke usoro Mu Space Engineering Spacecraft), ma ọ bụ naanị Haruka (は inac) bụ satellite redio nke Japan nke dị mita 8 n'obosara nke e ji mee ihe maka Very Long Baseline Interferometry (VLIB). Ọ bụ nke mbụ a raara nye na mbara igwe VLBI.

E debere ya na orbit elliptical nke ukwuu na elu apogee nke 21,400 km na elu perigee nke 560 km, na oge orbital nke ihe dịka awa 6.3.   Usoro a nyere ohere iji foto nke isi mmalite redio nke eluigwe site na satellite na njikọ ya na usoro telivishọn redio nke dị n'ala, nke mere na e nwetara ma ọ dị mma (u,v) ụgbọ elu na mkpebi dị elu.

Ọ bụ ezie na e mere ya iji hụ na bands atọ: 1.6 GHz, 5.0 GHz, na 22 GHz, a chọpụtara na mmetụta nke band 22 GHz emebiwo nke ukwuu mgbe a gbasịrị ya, ma eleghị anya site na mgbagwoju anya nke ọdịdị efere na mbido, si otú a na egbochi nchọpụta na bands 1.6 GHz na 5.0 GHz.      

A malitere HALCA na Febụwarị 1997 site na Kagoshima Space Center, wee mee nchọpụta VSOP ikpeazụ ya n'ọnwa Ọktoba afọ 2003, karịa afọ 3 e buru n'amụma, tupu ọnwụ nke njikwa àgwà. A kwụsịrị ọrụ niile na Nọvemba 2005.
