Currently proposed space-based gravitational wave detectors consist of satellite arrays deployed in an equilateral triangle either in the ecliptic plane or in a precessing plane tilted at 60° with respect to the ecliptic. This paper summarizes recent calculations of how well these two types of detectors can resolve the angular positions of two kinds of sources: low-mass compact binary sources and massive-black-hole binaries just before coalescence. Our results show that including higher-order post-Newtonian terms in the gravitational wavefunctions is important when predicting the angular resolution of ecliptic-plane detectors. © 2000 American Institute of Physics.
