The GNSS device you are asking about is called a Geodetic GPS. It uses several channels and constellations (GPS and GLONASS)
They cost upwards of 600k for a pair I think. These guys http://www.spectraprecision.com/welcome-85.kjsp?RF=PRO-EN have a local dealer http://www.osl.co.ke/
They can advise you further.
Maybe Laban's solution is more cost effective.

You can also get two independent GPS dongles and do some math to improve accuracy. Kalman filters & the normal distributions are your friends: http://tiny/gkwjw7ck/googsear
I think the free google self driving car class had a very nice video about this. Quite intuitive once you see it.
