I was just notified by a supplier of gps modules in RSA that this product has become available locally(RSA). I'm not sure how long this has been out in the rest of the world, but the following statement had my attention : NEO-6P GPS module for Precise Point Positioning....OK, what is PPP, and how accurate is it exactly. The guys at ublox claims positional accuracy of <1m. http://www.u-blox.com/en/gps-modules/neo-6p-/neo-6p.html
This is brillian for a L1 receiver. Then the small print - it can achieve and maintain this level of accuracy in static or slow moving applications. It is priced at around 1.5* the T chip's price and also has the raw data output capability that can be used in achieving a RTK fix (OpenRTK lib. ect).
Looking ahead in the quest for affordable, reliable 5cm accuracy receivers, I can not help but wonder when we will see a L1+L2 receiver from ublox at a price that does not involve selling a kidney. Are these guys going to stay with the mobile device position market? Will this market's demand for more accurate solutions push them to release technology they already posses (I'm speculating, but pretty sure). Can't wait for the NEO-6RTK.
