What is it these u-blox device can do that a cheaper Motorola Oncore
can't?   Depending on the version the Oncore has for 50 to 5 nS
one-sigma error on the timing pulses and can do either 1PPS or 100PPS.
  Single unit prices are from $18 to $60 very good documentation is

If the u-blox was somehow much better than a Trimble thunderbolt or
Motorola Oncore MT12T I'd buy one even at the above price.   But
really these older GPSs are already at the single digtit of
nanoseconds level and I don't see room for improvement except....

If the L2 band is also used.   This is the way to get order of
magnitude improments
