# STRF
**strf** is the satellite tracking toolkit for radio observations (RF). The software is designed to allow tracking of satellites from radio observations, using Doppler curves to identify satellites and/or determine their orbits.

This repo is a downstream port of STRF from proprietary pgplot
to libre giza.


# Setup
Thus.

```
sudo apt install giza-dev git make gcc gfortran libpng-dev  \
    libx11-dev libgsl-dev libfftw3-dev dos2unix unzip

git clone https://spacecruft.org/spacecruft/strf
cd strf/
make
sudo make install
```


# Use
