After recalling its working tenets, the contribution introduces to the technological (including computational) challenges facing

the actual realization of a compact antenna in space that, complementary to current or future facilities, utilizes (sub)-micro-arcsecond

astrometry to estimate strength and pin-point direction of GWs, i.e., by using suitable natural star-like close pairs as antenna “arms”.

Finally, some of the designs, reduction strategies, and lab activities carried out by the ASTRA Team are presented.
