Hello all,

A> suggestions on how to achieve this can be fount here :-
A> https://www.dexterindustries.com/howto/run-a-program-on-your-raspberry-
A> pi-at-startup/

I do it this way:

sudo nano /home/pi/.config/lxsession/LXDE-pi/autostart
At the end of that text file add your app, in my case it is this:
@/usr/local/bin/opencpn

OpenCPN is ECDIS for sailing chart navigation on all kind of see/inland waters.
It can also display AIS signals from the VHF-marine band if connected to an AIS
receiver or transponder. Even RTL-SDR can be used as an AIS receiver.
But then you need a USB-GPS mouse for the position information.
In the EU at ships larger than 20 meters long Class A AIS+ECDIS in Inland ERI
Mode (NOT SOLAS Mode) is mandatory at the river Rhine and on almost all
the inland waters of Germany.
The RPi 2B/3B/3B+ with Raspbian Linux + OpenCPN 4.6.x or higher toghether
whitch all the S57 digital chartmaps from the EU governmental RIS
organizations is the cheapest way to have an official accorded ECDIS
when used with a monitor of at least 1000 x 1000 pixels in Information Modus.

I'll support recreational skippers in this matter.
There is also a certified Navigational Mode with coupled radar,
but that is more complicated and until now not doable with a Pi as host
computer ;-(.

Note: the Raspbian Linux directorymap .config is normally hidden.
Turn on "show hidden" in the viewer to see such directortmaps.
Good luck.

That (simpliest) way is not always the correct (legal) one.
