GPS Tracklogger may be used as an extension to the GPS receiver. Since it works with the older models too, it could act as an upgrade. You may consider buying it, especially when your receiver has limited track recording functionality.

The unit uses NMEA protocol to communicate with the GPS receiver. This is the most common protocol used by GPS receivers. The track data may be downloaded to PC by means of various applications, which support MLR / Log_It protocol (e.g. GPSDump). A special cable (null-modem) is required (it may be purchased with Tracklogger). In order to connect Tracklogger to GPS, standard GPS data-cable is needed (the same that is used to connect GPS to PC).

Rugged and pocket-size plastic case (the case size may vary insignificantly) is suitable for all kind of outdoor activities. GPS Tracklogger works on two AA size batteries (or rechargeables). One battery set lasts for at least 400 hours of continuous work (logging). Since it consumes a little power, GPS Tracklogger can even work on used GPS batteries.

GPS Tracklogger is equipped with small LCD display and green LED diode indicating proper work. The LCD display shows reports about current logger's state.

Successive screens displayed by the device during operating:

  1. Intro screen:

    Tracklog/ver 2.01

  2. Memory state:

    used 2% /56512

  3. Battery state:

    battery /2.45V

  4. GPS Tracklogger is ready to work:


  5. During the work, the device shows actual time (UTC/GMT) and number of visible satellites. Flickering characters (|, -) means proper work.


    Between some screens the actual memory (2) and battery (3) state are shown.

  6. There are some additional screens like: low battery warning, low memory warning, etc.

Configure track resolution

The current software version enables to skip custom number (from 1 to 254) of track points. That significantly extends logging time. Usually, GPS receiver sends position every 2 seconds. When the skipping function is off, the logger memory lasts for about 150 hours of continuous work. That is enough for a medium trip. For a longer trip, the skipping function is required. It is possible to extend logging time up to a year (the batteries would die months earlier), but there is a catch - extending logging time decrease track accuracy.
