c) Transmission of the Tracking Data („TRACKDATA")
The command TRACKDATA only works via text message if SMTP and GPRS have been set first.
After receipt of this command, the GX111 will send an email via SMTP server with the tracking data as an attached
file. The size of the file can be up to approx. 3.26 MByte.
The tracking data are present in CSV format and prepared for further processing, e.g., in a spreadsheet programme
(e.g. Microsoft Excel).
The data are present in the text file as described below:
Date, time, latitude, direction, longitude, direction, track name <line change>
Example: 13.05.2013,16:10:41,01156.6192,E,4932.4173,N,Name
The time is indicated in UTC time, the GPS data are indicated in the format „NMEA-0183", the name cor-
responds to the respective programming by TRACK command
Conversion of tracking data (NMEA) to decimal digits:
Latitude:
Longitude:
Command to read the tracking data:
The following command indicates which area of the tracking memory is to be sent by email:
TEST TRACKDATA <First entry> <Last entry> #1513
First entry:
Last entry:
Value range:
Example:
TEST TRACKDATA 420 421 #1513
Memory:
Based on this count, the command would return the two memory values in the positions 420 and 421 by email.
A new tracking entry would push in new values „at the top" into position 1, which would push the last entry
out at position 64512 and thus delete it.
The count generally starts at the latest (newest) tracking point and counts backwards into the past.
01156.6192 = 011 degrees, 56.6192 minutes = 011 + (56.6192 / 60) = 11.943653 degrees
4932.4173 = 49 degrees, 32.4173 minutes = 49 + (32.4173 / 60) = 49.540288 degrees
