How do i interpret gridreferences ?

Rölli · 08-13-09, 10:38 AM

When receiving a contactreport by radio it often reads in four digits. I untherstand AM52 but what does for example AM5233 mean?

The grids are broken down even further to give a more precise location. That is how the Kriegsmarine kept long/lat out of the equation. For game purposes, it means diddly squat, the mod you are using is for immersion. And welcome to subsim sir!p>

In the lower right hand corner of the SH3 map, I think there might be a small reference box on how the Grid Reference works.

And yes.. the majority of radio messages are strictly for immmersion.

If your determined to convert them, try this:

This is the second thread since last night on the subject of immersion map grids.

Twice now an alarm has went off wondering what the GWX4 team has in store for us useing the SH4 map.

I know I'll be reading those radio messages more closely.

GWX4 will be takeing us to another Level.

Thank you for your replies and for the welcoming

I'll take a look at what you ( all ) have said. I know its for the immersion but i like to untherstand what i'm being told anyway. It's more fun

Pardon my english ( typos etc ) it's been a while since i've used it

In SH4 there are latitude and longitude markings on the map. The U-boat Missions Add-On keeps these, but also adds the Kriegsmarine grids - right down to the 4-digit level.

In my own personal hand-written logs for SH3 I make daily radio reports with 4-digit grid references. I do this by using a small grid square sheet I printed out, and laying it against the screen grid. This gives me a close enough approximation that I can guess the precise sub-grid pretty closely.

Rölli,
Your english is fine.

So...those messages I get from BdU saying, "Hugely big passenger liner, uptazillion tons, spotted by Luftwaffe in BF13. Pursue and sink," are just flavor? Had I known that, it would have saved me lots of time and fuel trying to hunt down HMS Empress of Britain, only to get a message upon arriving in said grid coordinate saying that U-84 already sunk it...

Sigh. But, immersion? A worthy cause!

Most of those messages I've received (mostly early war period) don't even provide enough information to reliably intercept them. Often the speed or course or time is missing in the message.

The real renown is in the contact icons (single units mostly) that silently appear on the map, showing general course and general speed. Or the convoy reports that do come with a radio message identical to the message panel line.

The longitude and lattitude reports are only interesting if you have a map-fetish, ... like me.

120 km for every degree N, S, E or W of the equator/prime meridian.
