But I read at http://msp.gsfc.nasa.gov/tdrss/scfaq.html that after the implementation of the Guam Remote Ground Terminal (GRGT) over the Indian Ocean, the ZOE has been eliminated.

Anyone any idea what these initials stand for? I thought at first they were lakes but I think they are in fact letters. andy, g0sfj
I was told once that TDRS 3/TDZ, at ZOE, is not used for STS/ISS operations, except during emergencies. I can't remember if it was because the limitation due to TDRS 3 or if Guam was not setup for STS/ISS operations. Originally TDRS 3 was placed at ZOE to support the Compton satellite.
