It's pretty trivial, you get three or so opposite geosync satelites and a few earth installations all actively looking for anomalies such as these. If the waves are attenuated by the object's physical movement away from us, first-off, the waves would be shifted into a different part of the spectrum, gamma rays being at the extreme, high-frequency end. The time a satellite detects a gamma ray burst and pinpoints its position and transmits a signal to an automatic ground-based telescope, to the time the ground-based telescope swings around and points at the gamma ray burster is six seconds. I just thought i'd share a little background knowledge.
