AIS CPA issue

Hi,

I have an issue with the CPA and TCPA of AIS targets. This issue occurred in version 5.8.x somewhere. When I downgrade to 5.6.2 this issue is not there.

The issue is that the CPA and TCPA of targets gets set and unset (showing - in the list) very quickly. It is only visible for a very short time and then is gone.

This is most clearly seen in the AIS target list window when sorting on the CPA column. In. version 5.6.2 this sorting stays even when the target list changes due to updates of the AIS targets.
On the map when drawing the vectors showing the CPA and its position, these lines are drawn for a very short time and then disappear.

Any sorting I do in the AIS target list window is also lost after 1-2 seconds.

Any ideas on what can cause this issue and how to solve it?


thanks,
Steef

Steef.
In AIS target list right column there is a check box "Auto Sort". If not enabled set it and see if it works as desired.

Re: Help / Cannot find port number in Linux Kubuntu

Hello everyone,


I'm running O on a Lenovo Ideapad Flex5.
I use Linux Kubuntu 22.04 fully updated.


I am trying to install my Camino 108 AIS transponder.
The 108 is only programmable by Windows, so I installed WINE and run the 108 installer OK, however I am not able to proceed with the Configuration as the installer cannot find the port automatically and I cannot set the port manually.


I tried to run:
spiv@spiv-Flex-5:~$ sudo dmesg | grep tty
[ 0.112029] printk: console [tty0] enabled
[ 4.718726] cdc_acm 1-1.4:1.0: ttyACM0: USB ACM device
[ 4.762453] usb 1-1.3: pl2303 converter now attached to ttyUSB0
[ 7952.695084] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0
[ 7953.593723] cdc_acm 1-1.4:1.0: ttyACM0: USB ACM device

[229296.972795] cdc_acm 1-1.4:1.0: ttyACM0: USB ACM device
spiv@spiv-Flex-5:~$

All that makes little sense to me.... whatever I tried to input in the port, I got the same error:
Can someone help me please?

Re: Help / FAQ

I was asked by Dave (bdbcat) to put in a Feature Request for how mbTiles wake up when OpenCPN is started. MbTiles used to wake up always ON, but some time ago I pushed through a request that they wake up OFF, as my mbTiles are HUGE & I was having performance issues with the computer I was using then.

This generated some negative reactions from some other cruisers, which I wasn't expecting, & would like to rectify.

Therefore, what I'm proposing is a 4-position "Radio-button" type switch in Options, so the user can determine how mbTiles start up:
  • Always OFF (default)
  • As they were when OpenCPN last shut down
  • ON unless the mbTiles are larger than [XX] GB
  • Always ON
If anyone has any thoughts on this, or if you'd like to up-vote this feature, please go to the Flyspray entry:
https://opencpn.org/flyspray/index.php?do=details&task_id=2923

You will have to log in if you want to comment or to up-vote this request.

Thanks!

Re: Help / FAQ

I am not a purist.

But I find running OpenCPN and SASPlanet concurrently works.

Build a (or a series of) SASPlanet database(s) by arm-chair exploration while online in winter in Canada. Base of x10 then x16 and +/-18 or 19 zooms.

Then run both concurrently when offline after the snow melts - approaching anchorages, reefs, passages, etc. w. Switch back to OCN for bathymetric data.

SASPlanet ship is an obvious red triange tracking across the saved database(s). Seems spot on wrt location.

What's wrong with that?

Ta to fellow-Canadian Paul Higgins and the O-charts team!

Re: Help / FAQ

Nothing at all wrong with this, Jeff. In fact, this is what we've been doing for several years, since 2019.

When doing this, you will probably find that a wider-screen computer is better. We use a 17" laptop. OK, we have older eyes...

You may also find that you need COM-port sharing software. In theory, OpenCPN is able to send its data OUT on a different COM-port, for other applications to use, but I've never been able to get this to work (probably my fault). Since Windows only lets a single app use a given data-stream from a COM-port, I just downloaded a tiny app that receives the GPS stream (in my case, my AIS stream) & then outputs that on as many (synthetic) COM-ports as you want. Then OpenCPN can use one of those, & SAS another.

You can use multiple SAS caches if you want, but for the most part, I just use a single (large) cache. Since I publish my mbTiles for other cruisers to download, I have lots of areas that I'm not going to be sailing to in my cache. But the SAS cache is only limited by the size of your hard drive. It's not like Google Earth, which limits the size of its cache.

But you will want to make sure that your SAS is using SQLite3 caches! This is in:
Settings/Options/Cache/Default Cache type (down at the bottom).

The original SAS cache was just a HUGE directory tree of individual tiles. This quickly got too large for Windows to even go through & count, let alone copy or backup. There's a conversion utility if you're using the old file-system cache. Feel free to PM me if you have problems here.

FWIW, since SAS isn't really installed (just unzipped) I have several installed on my computer, each with a different display configuration. One is "SAS for Navigation" & another is "SAS for Sat2Chart", since Sat2Chart requires a specific configuration that's not really optimized for navigation. Since I want both to use the same cache, I put that cache at the same directory level as my SAS installations, & then point each installation at that same cache.

That is, I have a D:\SAS Planet folder, & under that I have folders for my different installations, as well as my SAS SQLite cache. You can change your cache locations at that same Settings/Options/Cache dialog, but then make sure that you shut down SAS so it writes that out to its config file.

Love that you're from that great sailing area of ... Banff?

Re: Help / FAQ

Tx for all the great ideas Jon, Sue and Ocelot!

We are currently in Mooloolaba after rounding Oz the first time. Fond memories for you!

Currently OCN runs on our SSD Black Cobra with a GPS/AIS feed from our Vesper XB9000 (that has the neurotic screen described by many).

SASPlanet from the Black Cobra GPS card.

I have tried GPS splitters with limited success. What splitter "tiny app" do you use?

Enjoy Kinabalu!

Thank you for that!
Following your link, it directed to the WINE userguide, there it said to run:
Quote:
ls -l ~/.wine/dosdevices/
Which returned this:

Name:	WINE CON <a title=Ports.jpg Views: 21 Size: 194.3 KB ID: 276784" style="margin: 2px" />


Then in the AIS Config program I selected 'Manual' and entered 33 as the port, it asked me to confirm 'forcing' the connection and then it allowed me to properly configure the Camino 108.

Re: Help / O Creates new ports

Hi again...


I managed to get O to connect to my Camino 108 AIS.
It now shows AIS targets, my position and heading;

However, (over time) there is something that happened in the Connection tabs.
I have 3 new Ports that I did not create with a BAUD rate of 150 and Position 9, in the pic below only the last one is se showing, the other is the AIS:

Jeff...
Jeff, we're on the road & I don't have my nav-computer with me.

I *think* it's called GPS-Gate, but I'm not sure. It sort of looks like trial-ware, but we've been running it for several years.

But a search on Google for "COM-port splitter" (or the many variants) yields several possible solutions, like this Free Serial Port Splitter

PS: Friends who cruised with us in the Philippines now say that they want a Mumby 48...

Re: Help / FAQ

Hello
My opencpn crash if Ihave any plugin activated.
It started when I upgraded ubuntu to 22.04.
After one update of opencpn it start to work again but stopped after a new update in ubuntu or opencpn, not sure there.

If I activate a plugin nothing happens, but crash if I close opencpn and start it again

Never seen anything like that. Yes, you can delete them. Select on at the time, "Remove connection" "Apply".

Hey Spiv, we have also the Camino 108 and did not have a problem.

But we had a problem with the heading info for the radar which might be related to the output of the Camino.

If you have a separate heading sensor & radar, make sure it's the only item supplying heading info to the radar.
