How long have we searched for a module like this one! We have even developed a software receiver just to get hold of the pseudorange, carrier Doppler and phase out of a receiver.
Having the so called "raw" measurements from a GNSS receiver allows for fancy-math algorithms that combine measurements from one or more receivers. There are multiple reasons to do so:
Note 1:The most should be aware that this receiver by default outputs raw observations in Skytraq-proprietary binary format at 20Hz on a serial port at 115200, 8N1. NMEA can be enabled using Skytraq's GPSViewer software.
To find some interesting results of this receiver with RTKLIB check Michele's Blog here.
