[tacgps] Low cost timing GPS for Smartbits

[edu at kender.es]

Well

I meant Spirent Smartbits Hardware...
(http://www.spirentcom.com/documents/1374.pdf) They are network traffic
generator. They have ports that can send and receive traffic and you can
develop applications to program it. If you use only a chasis, you can
measure propagation delays. If you use two chasis (transmiting from one to
a wireless system and receiving on the other chasis) and you don't have
Internet access you can't get a good clock reference. An option is to use
GPS systems. Spirent does offer an solution, but the information on the is
so loose it's difficult to know how difficult is to adapt an external
source.

We (at Univiversity research group)  would like to get 2 GPS timing
systems at a faction of the cost of "official Smartbit solution" They use
58503 (HP?) or NanoSync hardware but I don't get information about the
interface levels (ttl or RS-232).
