    Default Navigation log grid references

    Am attempting to decipher a navigation log recorded by a Coastal Command navigator. It refers to geographic points by what I assume are grid references such as 'HBCU 4150' and 'DMDX 3752'.

    Did this grid system have an official name?

    TIA:

    Robert

    Hi Robert,

    this has been discussed already several times on this forum and the right person who might help is Ross.
    As I remember Ross always said that it is also important the date as the letter combinations used for the latitude and longitude was changing time to time.

    I have not found on official name and it Is described in various formats as:

    Position Reporting or Signal Position Reporting Code and all combinations between.

    Changed at midnight GMT on a moveable date.

    Period between changes varied from 14 days to six months depending on Command/Force activity and any recent losses which may have compromised associated SYKO transmission codes.
