- I am not sure of the current status of this proposal, but I was at a meeting
- discussing a related topic about six months ago. Apparently, there is about
- 50lb of unused capacity on GPS (to rephrase, the satellite can afford to be
- 50lb heavier, and there is space for 50 extra lb of payload). In future
- designs perhaps a S&R package could be put on the satellite.
-
- The people proposing this sounded very serious. I personally would think
- that this would add much more than 50 lbs of weight, in communications
- capacity alone. I wish I still had the reference materials. Has anyone else
- heard of this idea getting seriously entertained?
