# goestools [](https://travis-ci.org/sam210723/goestools) **This is a modified version of goesrecv (originally by [Pieter Noordhuis](https://github.com/pietern/goestools)) for the LRIT downlink transmitted by GEO-KOMPSAT-2A (GK-2A) at 128.2°E.** **The rest of the xRIT receiver project for GK-2A can be found in the [xrit-rx repo](https://github.com/sam210723/xrit-rx). Older code for the now retired COMS-1 satellite can be found [here](https://github.com/sam210723/COMS-1).** ## Building Install dependencies for ```librtlsdr``` and ```goesrecv```: ``` sudo apt-get update sudo apt-get install -y build-essential pkg-config cmake git zlib1g-dev libairspy-dev libusb-1.0-0-dev ``` Build ```librtlsdr``` from source: ``` # Download, compile, and install librtlsdr git clone https://github.com/steve-m/librtlsdr.git cd librtlsdr mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr -DINSTALL_UDEV_RULES=ON .. sudo make -j2 install # Load udev rules and blacklist the DVB driver shipped with the OS sudo cp ../rtl-sdr.rules /etc/udev/rules.d/ sudo ldconfig echo 'blacklist dvb_usb_rtl28xxu' | sudo tee --append /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf sudo reboot ``` Build ```goesrecv``` from source: ``` git clone --recursive https://github.com/sam210723/goestools cd goestools mkdir build cd build cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local make sudo make install cd .. cd .. cp goestools/etc/goesrecv.conf goesrecv.conf ``` ## Running The ```-i``` option specifies the interval (in seconds) that goesrecv will output information to the console. The ```-c``` option specifies a path to the goesrecv config file. ``` goesrecv -i 1 -c goesrecv.conf ``` ## Changes * [Update LRIT and HRIT symbol rates](https://github.com/sam210723/goestools/commit/9fd004cc2aef0f7620703321314443f4c8d6b634) * [Disable building of goeslrit, goesproc and goespackets](https://github.com/sam210723/goestools/commit/73bae4e01bebd3b3bf347f8afc731bda2549dfe8) * [Change LRIT frequency](https://github.com/sam210723/goestools/commit/af7cfc9a8ee08d096f50b07bde59101be3635a43)
