Mid-war Naval Coordinate System

[Don Caldwell]

I need help converting the coordinate system used by III./JG 2 in 1943 to latitudes and longitudes or the Luftwaffe Planquadrate grid. Franek, I know you were working on a conversion program several years ago. Any luck?

All of the naval map converters i've seen on the internet start from a letter-number system. JG 2 wasn't using this. A typical example would be "3715/14 West" for a location south of Brittany.

Any help would be appreciated.

Horrido!

Hello Don,

Take a look here http://www.gyges.dk/reporting_grids.htm

best regards,

...whilst I have maps which show PlQ which can be converted to lat & long

Thanks for the help. However, I'm not there yet. Everything I can find on Naval maps on the web refers to a grid system with the major sectors designated by two letters. A complete location would be those two letters followed by four digits. That's the map system the gyges site refers to, Tomislav -- plus I can't get its converter to work (I can't execute the .exe file). I did get a printout of a map covering England & northern France from the site, which is the territory I need. I need to work with it and see if its two-letter major grid sectors match up somehow with the "14 West", etc., which III./JG 2 was using. These look like the Luftwaffe grid's designations for the major squares.

Chris -- do your maps have the two letter designators for the major squares, or something similar to the III./JG 2 system?

Horrido!

Hi Don,
If you open the link refered to above you find a converter:

and here is a map with "the major squares":

I can't get your conveter program to execute (this is apparently a Mac/PC thing). However, if I could, I don't think it would help. The major grid IDs in the III./JG 2 system were from the Luftwaffe map: 04 Ost, 05 Ost, 14 West. These look OK for the territory the unit was flying over. But the rest of their location IDs are four digits, not from the Luftwaffe map and apparently not from the naval map either. I can assume that they were in the naval sector "BF" from the map you linked me to. But the four digits don't match the naval map.

Thanks again, but I'm stuck. Maybe the SIG Norway people have seen something similar? Andreas?

Horrido!

Hi Don,
The Lw used two fighter grid systems. The old one used the four digits, attached.

Have you tried the GNMV converter found here:
http://www.gyges.dk/LUMA.xls
using that 14W3715 works out to 46*52'N002*45'W
please also see attachmeny.

The LUMA converter works perfectly! Problem solved!

Many thanks,
