     An Air Force Delta 2 rocket is to the launch the Global Positioning 
System Block 2R-2 spacecraft on the evening of July 22. 

     The McDonnell Douglas-built rocket is scheduled for liftoff from pad 17A 
at Cape Canaveral Air Station, Fla.,during a launch window of 11:43 p.m. to 
12:12 a.m. EDT (0343-0412 GMT). 

     GPS 2R-2 is identical to the military navigation satellite lost in the 
January explosion of a Delta 2 from Cape Canaveral. The satellite, built by 
Lockheed Martin, provides users with precision information such as location 
anywhere in the world within a few feet, their speed within a fraction of a 
mile per hour, and the time within a fraction of a second. Once on orbit, the 
satellite will replace an aging GPS spacecraft in the constellation. 

     The launch can be seen domestically on satellite Galaxy 4, Transponder 9 
beginning at 11:30 p.m. EDT (0330

If anyone has preliminary elsets I would like to see if it is visible soon
after launch.
Will search some archives for previous launches.
