Prerequisites and Steps to Fully Enable GNSS Features

Prerequisites:
• Linux Kernel 4.19+. Supported kernels can be found at:
https://cateee.net/lkddb/web-lkddb/GNSS_UBX_SERIAL.html
A long-term support kernel is strongly recommended. Check:
• Ensure that the gnss, gnss_serial, and gnss_ubx modules are all enabled in kernel config file.
• Python3.9+ and pip3 20.2+
• scons 4.2.0 or later
Note:
Ensure that these components are installed correctly before any other step. During the
installation process, ensure that there are no hidden error messages. After the installation,
check if scons is present.
(# scons -v)
Steps to install gpsd:
Note: For additional information, refer to https://gpsd.io/installation.html.
1. If you cannot find the /dev/ttyGNSS_BBFF file, ensure that you are using tthe E810-XXVDA4T with
the optional GNSS installed and the latest driver and NVM (see
2. To check the TTY interface configuration:
#stty -a -F /dev/ttyGNSS_8400
3. To check the TTY interface configuration writable:
#stty -F /dev/ttyGNSS_8400 9600
It is recommended to stay with 9600 baud rate for best stability.
4. If you receive any error message from the above two commands, follow the trouble shooting guide
to solve OS and kernel dependencies:
https://gpsd.io/installation.html#_check_that_your_system_configuration_will_allow_gpsd_to_work
5. A minimum build of gpsd can run near bare metal; C runtime support is the only requirement. The
test clients and various additional features have additional prerequisites found at:
https://gpsd.io/installation.html#_check_your_installation_prerequisites
6. Before installing gpsd on your system, ensure that all parts of any previous installation have been
removed. Do not mix gpsd parts from different sources. The gpsd clients and the server must be
of the same version.
7. Install gpsd:
#git clone https://gitlab.com/gpsd/gpsd.git
#cd ./gpsd
#scons -c
#scons udev-install
#gpsd -V
Note: It is important to install system dependencies using your system package manager first,
before installing SCons or Python dependencies.
