GPS Tracking with your DOVADO UMR
NOTE: Requires at minimum version 4.0 firmware!

  • Someone sailed off with your boat?

  • Want to know where your vehicle has been?

  • Got lots of UMR's out in the bush you can't keep track of?

  • Do you suspect your kid brother of driving your car too fast?

  • Stuck in traffic and annoyed with receiving phone calls asking where you are every five minutes?

    No worries, now you can locate your UMR
    (or rather, its host!)


    Now you can combine your DOVADO UMR with a standard USB-based GPS receiver (most use the same PL-2303 driver!) and you've got yourself a flexible, low-cost and advanced GPS tracking solution!

    Operating Modes

    There are two main methods of using positioning in the DOVADO UMR:

  • USB-based GPS receiver inserted in the DOVADO UMR.

    Summary: This is useful if the DOVADO UMR is in a mobile scenario where its host vehicle can be tracked from a remote location.

  • Enter fixed Latitude and Logitude co-ordinates in the DOVADO UMR.

    Summary: Handy if for instance you have a lot of DOVADO UMR's with fixed locations and want to keep note of their position. Further (coming) applications that depend on geography will gain benefit from this feature.


    Supported Features

    SMS Remote Control
    If your SIM card and 3G USB modem support SMS in the DOVADO UMR, then you'll be able to utilize this feature to quickly request the geographic position of your DOVADO UMR from your mobile phone!

    NOTE!: Make sure that your DOVADO UMR is configured for SMS Remote Control.

    Send the STATUS command by SMS to your DOVADO UMR, and you shall receive a reply that looks like this:

    (sorry about the lousy photo quality!)

    Web access
    When accessing the DOVADO UMR's administrative pages, you will always find the current position displayed in the Connection Status Overview Bar. These values will only be displayed if GPS has been enabled or fixed coordinates have been entered.

    If using GPS, these figures will be updated once a minute.

    If you are running a Dynamic DNS service/static IP address on your DOVADO UMR, you can access it from a remote location, and find its current location via the POSITION->MAP page. The IP address of the UMR can also be retrieved by the "STATUS" SMS command.

    FTP logging
    Allows your DOVADO UMR to automatically upload all the accumulated positioning data over a 15, 30 or 45 minute period. The data will then be uploaded to an FTP server site as defined in the example below.

    The log files contain information in $GPRMC format, which looks like this:

    $GPRMC,181209.000,A,5917.0320,N,01759.6636,E,35.65,316.55,160709,,*3C

    Post-processing logged data

    A very handy tool we came across for allowing you to import the log file data into a program such as Google EarthTM is the KML Generator, developed my Jacob Madsen. It allows you to import the log data, process it for preview purposes (shows lots of information), and output a KML file for use with Google EarthTM as shown below.
