[time-nuts] high (spacial) precision GPS in Kickstarter

[Anders Wallin]

AFAIK 'normal' RTK does not provide a clock solution. There's something
called 4D RTK which does:
http://saegnss1.curtin.edu.au/Publications/2010/Feng2010Four.pdf
apparently the results can be very good - but I think the errors quoted are
for time-transfer between two RTK receivers (?).

If there are papers comparing time-transfer with dual-frequency PPP to this
4D RTK I'd be interested..
