I'll give the solution first, always nice to have a fix before knowing the problem:
I added "#include <stdint.h>" to the top of demod.c and it now compiles without any errors.

The problem was when compiling on ARM architecture I got the following:
root@bananapi ~/src/demod/build (git)-[master] # make

Hi,
At the step ' Compiling rustc-serialize v0.3.18'
There is an error:
error[E0642]: patterns aren't allowed in methods without bodies
--> /home/mark/.cargo/registry/src/github.com-1ecc6299db9ec823/rustc-serialize-0.3.18/src/serialize.rs:145:45

145 | &f_name: &str,
| ^^^^^^^

With a bit of research, it turns out that if you update rustc-serialize with this line:
cargo update -p rustc-serialize

And then run the compile instruction, the error goes away and everything compiles fine.

Hello, I'm testing your software for NOAA signal recording.
I don't understand what happen with the location that software interptrets. I write the command of your example:
rtl_fm -f 437.5M -s 1024000 -g 20 -M raw - | doppler track -s 1024000 -i i16 --tlefile cubesat.txt --tlename 'ESTCUBE 1' --location lat=58.26541,lon=26.46667,alt=90 --frequency 437505000 --offset 5000 > zero.iq

and I recive:

Whaever location I want, software interprets alt=0,long=0,alt=0.

Also, I always recive doppler correction =-0.00Hz.

If you know what is happening, I would apreciate your helful.
Thanks you.

Hi Could please help

I am compiling on Ubuntu 16.04

I've recently downloaded and successfully compiled Doppler however when I execute it, the program stops with the message that just says Killed. I was able to get the following from strace when I attempted to execute the program. I'm trying to figure out why this is happening. Any help would be greatly appreciated:

I'm trying to use doppler on GQRX's raw files like this:

cat gqrx_20220804_154702_137100000_80000_fc.raw | doppler track --frequency 137100000 -i f32 -o f32 -s 80000 --time 2022-08-04T15:47:02 --tlefile weather-tle.txt --tlename 'NOAA 19' --location lat=x,lon=x,alt=x > fixed.raw

But resulting file is neither playable in GQRX nor SDR++

I tried to convert resulting file to i16 format using sox:

sox -t raw -e floating-point -b 32 -c 2 -r 80000 fixed.wav -t raw -e signed-integer -b 16 -c 2 -r 80000 fixed_i16.raw

and i got:

sox WARN dither: dither clipped 34814543 samples; decrease volume?
sox WARN sox: `dop.wav' input clipped 39521951 samples

while before the doppler shift there was no problem with this command

As I know GQRX records raw file in little endian float 32 bit, 2 channel IQ file (one for I and one for Q)

What is the problem?

Hallo im trying to compile doppler but i still get an issue.

It would be convenient to use it like this:
