"The article mentioned a software receiver based method, more flexible to try different approaches to the problem. Currently our implementation is hardware based, less able to try unconventional methods. Thanks!"

"Thank you Felipe for the suggestion, we'll check it out. With fair performance RTK antenna around $100 ~ $150 apiece, I'm not sure if it's feasible for commercial product to implement this though."

"The Venus828F on the NavSpark-mini is actually a GPS/Beidou receiver. Due to different RFIC used inside, the Arduino NavSpark-BD library cannot work with Venus828F, but the Arduino NavSpark (GPS) library does work with Venus828F.

Oliver Huang replied to Al's discussion Can the NS-RAW with it's 100MHz 32bit LEON3 Sparc-V8 run the RTKLIB RTKRCV positioning
"We'll later think of a connector type solution for ease of use. It still output NMEA in 9600 but with more decimal digits; so should easily interface with Bluetooth."
