[time-nuts] RINEX for Android

[Björn]

Hi Jim,

Teqc is not a Windows-only program.  There are actually several ARM/Debian compilations. I assume some receiver protocols have been implemented with NDAs attached (hey Trimble...) and that might be one reason not to distribute source code. However if JPL would have a long term need for a specific build - Perhaps Unavco would consider supporting that. 

https://www.unavco.org/software/data-processing/teqc/teqc.html

Teqc does translation (binary to Rinex conversion), editing of rinex and quality control of rinex data. 

Not sure if that is something you want/need to do at your Beaglebone or what post processing package you intend to use.  Some post processing softwares might eat uBlox binary natively - all likely support rinex.

Before I go out and write python code to push characters out the serial port and get the output, I was hoping that someone had done some of this before.. I can do the conversion from a binary file to RINEX somewhere else.
