u-blox (SIX:UBXN), a global leader in wireless and positioning modules and chips, launched today the NEO-M8P GNSS receiver modules, which are compatible with both the GPS and GLONASS satellite-based navigation systems and deliver high performance down to centimeter-level accuracy.
Measuring merely 12.2 x 16 x 2.4 mm3, NEO-M8P is the smallest high precision GNSS RTK (real time kinematic) module available on the market. The u-blox rover (NEO-M8P-0) receives corrections from the u-blox base receiver (NEO-M8P-2) via a communication link that uses the RTCM (Radio Technical Commission for Maritime Services) protocol, enabling centimeter-level positioning accuracy. The RTK algorithms are pre-integrated into the module. As a result, the size and weight are significantly reduced, and power consumption is five times lower than existing solutions, thus cutting costs and improving usability dramatically. Customers can further reduce their R&D efforts, as they do not have to spend significant resources and time to develop an in-house host-based RTK solution.
RTK technologies have been used for some time in low-volume niche markets, such as surveying and construction. Due to high costs and complexity, this enhanced positioning technology has been inaccessible for most other uses. Emerging high volume markets, such as unmanned vehicles, require high precision performance that is energy-efficient and low in costs. Other application areas include agriculture and robotic guidance systems, such as robotic lawnmowers. The u-blox NEO-M8P answers these demands for a small-sized, highly cost-effective, and very precise RTK-based module solution.

"
A recent technique, called Differential GPS (DGPS), improves the GPS system by referencing a network of ground-based stations – increasing accuracy to within 3 feet. But this still isn’t precise enough for many modern technologies."
10 years ago I have experimented with IMU + GPS integrated car navigation system
in poor GPS signal/no GPS signal environments.
DGPS should be named D1GPS D2GPS D3GPS to denote specific referrential technology solution ( Internet based, GCS, IMU ...)
@Darius
Its not DGPS technology, read the article.
@dionh,
DGPS technology, described by you, is 10+ years old technology
and has been tested more than 10 years ago in New York, Manhattan
to work on no-GPS signal streets.
Accuracy of IMU + GPS is not great since geolocalization error calculated with IMU increases the longer you drive with no GPS signal.
I have found this also interisting

Very good news, the RTK issue is really coming to masses. At least massive cost reduction for centimetric accuracy. Amazing step forward if you only look two years ago.
With such cost cut, and probable success for RTK, I am sure differential signal sources will spread widely.
Really excellent news, all-in-one RTK GPS from Ublox.
I expect the price of RTK GPS to fall to $200 by the end of 2016 (ground station + rover kit) since Ublox has many competitors interested to buy raw data Ublox GPS chips
and offer RTKLib add-on on their own.
I am still awating research paper on claimed accuracy of RTK GPS supported by long-term live tests.
