Swap memory
OpenCV needs a lot of memory to compile. The latest versions want to see a minimum of 6.5 GB of memory before building. Your swap space is limited to 2048 MByte by default. To exceed this 2048 MByte limit, you will need to increase this maximum in the /sbin/dphys-swapfile.

sudo nano /sbin/dphys-swapfile
sudo nano /etc/dphys-swapfile

Копиране на директорията на потребител pi в Raspberry OS с rsync отдалечено:
rsync -chavzP --stats pi@remote.host:/home/pi /path/to/local/storage
където remote.host е IP адресът на Raspberry Pi, а /path/to/local/storage локалната директория, където ще бъдат копирани данните.
1. Сваляне на изходния код (версията на RTKLIB Explorer)
git clone https://github.com/rtklibexplorer/RTKLIB.git
cd RTKLIB
cd app
cd consapp
2. Инсталиране на необходимите инструменти и програми за изграждане (компилиране) на RTKLIB
sudo apt-get install build-essential
sudo apt-get install automake
sudo apt-get install checkinstall
sudo apt-get install liblapack3
sudo apt-get install libblas3
sudo apt-get install gfortran
3. Изграждане и инсталиране
sudo make
sudo make install
4. Обновяване
cd RTKLIB
git pull
При обновяване се повтаря точка 3.
