  Space-based gravitational wave detectors will have the ability to observe
continuous low frequency gravitational radiation from binary star systems. They
can determine the direction to continuous sources with an angular resolution
approaching tens of arcminutes. This resolution should be sufficient to
identify binary sources as members of some nearby globular clusters. Thus,
gravitational radiation can be used to determine the population of hard
binaries in globular clusters. For particularly hard binaries, the orbital
period may change as a result of gravitational wave emission. If one of these
binaries can be identified with a globular cluster, then the distance to that
cluster can be determined. Thus, gravitational radiation may provide
reddening-independent distance measurements to globular clusters.
