Andrew,

?

Do you have a legend that breaks out the object attributes in the object.pos file?

?

Like what does this all mean:

*111111z4738.27N/12243.53Wr

I feel like the *111111z is time and equals permanent.

?

What’s the rest mean if I got that right.

?

No, you'll have to look in the APRS Protocol Specification document for that.

According to chatGPT;

This string appears to be an?APRS (Automatic Packet Reporting System) location beacon, commonly used in amateur radio for reporting position. Here's how to interpret it:

*111111z
- The?*?might indicate a comment or other specific data type, depending on the context.
- 111111?is the?timestamp?in UTC (Coordinated Universal Time) in the format?DDHHMM:
  - DD?= Day of the month (11th day, in this case).
  - HHMM?= Time in hours and minutes (11:11 UTC in this case).
- z?indicates that the time is in?Zulu time, another name for UTC.
4738.27N
- This represents the?latitude?in degrees and decimal minutes:
  - 47?= 47 degrees.
  - 38.27?= 38.27 minutes.
  - N?= North latitude.
To convert to decimal degrees:
$47 + \frac{38.27}{60} \approx 47.637 8^{°}$ .
12243.53W
- This represents the?longitude?in degrees and decimal minutes:
  - 122?= 122 degrees.
  - 43.53?= 43.53 minutes.
  - W?= West longitude.
To convert to decimal degrees:
$122 + \frac{43.53}{60} \approx 122.725 5^{°}$ .
r
- This is the?symbol indicator?that tells what kind of object this is. In APRS, different symbols are used to represent various things, such as cars, planes, or weather stations. The specific meaning of?r?would depend on the APRS symbol table being used.

Final Interpretation

This beacon is reporting a position:

Latitude:?47.6378° N
Longitude:?122.7255° W
Timestamp:?11:11 UTC?on the?11th day?of the month.

This location is near Seattle, Washington, USA. If you have further context, such as the type of object being tracked (e.g., a mobile station, weather station, etc.), it could provide additional details.

I was just fixing up some YAAC help files, and noticed that there is a detailed explanation of the Object record format in the built-in help. Just look for the help for File->Load->Objects and Items.

Sorry about my previous incorrect statement; it's been years since I wrote that particular help file.

According to chatGPT;

This string appears to be an APRS (Automatic Packet Reporting System) location beacon, commonly used in amateur radio for reporting position. Here's how to interpret it:

  1.  *111111z

     *   The * might indicate a comment or other specific data type, depending on the context.
     *   111111 is the timestamp in UTC (Coordinated Universal Time) in the format DDHHMM:
        *   DD = Day of the month (11th day, in this case).
        *   HHMM = Time in hours and minutes (11:11 UTC in this case).
     *   z indicates that the time is in Zulu time, another name for UTC.
  2.  4738.27N

     *   This represents the latitude in degrees and decimal minutes:
        *   47 = 47 degrees.
        *   38.27 = 38.27 minutes.
        *   N = North latitude.

To convert to decimal degrees:
47+38.2760≈47.6378°47+6038.27?≈47.6378°.

  3.  12243.53W

     *   This represents the longitude in degrees and decimal minutes:
        *   122 = 122 degrees.
        *   43.53 = 43.53 minutes.
        *   W = West longitude.

To convert to decimal degrees:
122+43.5360≈122.7255°122+6043.53?≈122.7255°.

  4.  r

     *   This is the symbol indicator that tells what kind of object this is. In APRS, different symbols are used to represent various things, such as cars, planes, or weather stations. The specific meaning of r would depend on the APRS symbol table being used.
