U blox has released the NEO-6P GPS module with standalone sub-meter precise point positioning (PPP).
PPP is made possible by a proprietary algorithm combined with ionospheric correctional data received from satellite-based augmentation systems such as WAAS, EGNOS and MSAS. The system achieves full accuracy with unobstructed sky view after only a few minutes of operation. The device comes in u blox industry standard NEO leadless chip carrier module form factor.
The device also provides complete GPS satellite raw data, allowing further accuracy improvement based on post-processing by an external host.
