RTKLIB Post-Processing With Alpha

Aside from being a 10Hz-capable GPS/GLONASS or GPS/BDS RTK receiver for real-time precision guidance control, and a Bluetooth RTK receiver for Android device used in GIS data collection, Alpha can also simultaneously log data to the 16GB SD-card if it's inserted, which can be later post-processed. This video shows how the logged data is converted to RINEX and processed using RTKLIB. Although only a few simple steps are shown, since the logged data format is shown to be compatible, more complex processing on the data could also be performed with RTKLIB.  

Alpha has maximum current drain of 180mA @ 5V. With a small, low-cost 6000mAh power bank, it could easily run for 30 hours!

Anybody get this to work? I have flown 3 missions now and i always get an error saying that there is no data to read. but if you open the file and it has lots of data logged. i think it has some thing to do with the file extension. the files i get are .DAT and in the video they show a .bin file. either way have not been able to get it to work.

Did you ever make headway with this, how do you use these? Sounds like you too are a drone pilot. I am curious.

Hi Chris,
The extension is not a problem. Please make sure you specify the correct format: RTCM or SkyTraq. I use RTCM in base and SkyTraq in Rover.

Hi Shane,
We are preparing a PPK demonstration with drone and flight control board. Will show you soon.

Please, let me also know when the process for ppk gets online.
I read the forum, but get stuck at converting .dat with rtklib-rtkconv : no such file format suported.
Thank you.
