Another way might be to use single-channel common view GPS. I've not checked recently to see if 100 ps is possible over a 1 km baseline. If so that would be a less expensive solution. Someone should dig into the RINEX mode of the ublox 6T. It's on my list but the list is long.
BTW, there are some LEA-6T modules (with patch antenna, compass, 1PPS led, and USB connector) intended for drone autopilot use on eBay for around $30 shipped from China. (Search for "LEA-6T".) Mine showed up on the day of my lightning strike, so I've barely played with it. It has the 6.something ROM, connects to u-center, and appears to output the +/-10 ns sawtooth error correction message and the RTKLIB compatible raw data.
