That's a good point. There are 2 obvious single points of failure in using TBolts. One is TBolt firmware (or obscure design error). The other is the GPS system. If you want to protect against things like firmware bugs, I think you have to get 3 independent designs. If you have 2 TBolts and 1 other receiver, a bug in the TBolt firmware will out vote the sane 3rd receiver. I don't know how much to worry about problems in the GPS system. The military probably considers it to be very important so I expect they have thought hard about how to keep it going. Politics might be important. For example, somebody might decide to turn selective availability back on. At the receiver, you obviously have to worry about things like a shared antenna with a splitter. Even if you have separate antennas, the cables probably run near to each other and the antennas are probably close to each other where they might get knocked out by the same snowstorm, bird nest, or object falling from the sky. -- These are my opinions, not necessarily my employer's.
