The end of the article is about the RTL-SDR dongles, and how for the money, its surprising that it can pick up and track the satellites, although I didn’t get out of the article that he was able to calculate a PVT fix from that data.
USB TV TUNER FOR MAC EBAY SOFTWARE
The first is about new developments in GNSS (GPS+Galileo+Glonass) particularly with regards to using Tomasu Tomaji’s INCREDIBLE RTKlib software ( ) with a subset of new hardware chips that enable access to RAW GPS DATA. Posted in gps hacks Tagged dongle, doppler shift, gps, sdr, tv tuner, usb Post navigation We can understand how that would work, but we’re glad he has the skills to actually make it happen because we’re at a loss on how the concept could be implemented. He plans to use an SDR acquisition algorithm to measure doppler shift in accounting for the slow clock speed of the dongles compared to standard GPS receivers. And does plan to implement real-time GPS data in his next iteration of the project. But depending on what you need the data for this might not be a problem. Would it surprise you that he can get location data accurate to about 20 centimeters? That figure doesn’t tell the whole story, as readings were taken while the dongle was stationary for three hours, then averaged to achieve that type of accuracy. But decided to see what other tricks they could pull off. You may remember seeing this same hardware used as a $20 option for software defined radio. These inexpensive TV tuner dongles can also grab GPS data.
