    GPS Chipset SiRFstar III



    From Wikipedia “The SiRFstarIII chip is distinguished from earlier SiRF chips and from GPS chipsets made by other manufacturers (Garmin or Trimble Inc for example), largely due to its ability to acquire and maintain a signal lock in urban or densely covered forest environments, and its faster time to first fix (TTFF), the time it takes for a GPS receiver to lock onto the satellite signals and determine the initial position. The enhanced abilities of the SiRFstarIII chips are made possible by several features:

    • A 20 channel receiver, which can process the signals of all visible GPS and WAAS satellites simultaneously.
    • The chip consumes 62 mW of power during continuous operation.
    • Receiver sensitivity of -159 dBm while tracking; GPS receivers based on this chipset have routinely performed better than receivers based on other chipsets. Reviewers have praised the SiRFstarIII chipset for its superior sensitivity and tracking capabilities.

      Usage Scenarios

      Geo tagging your pictures

      Make sure your digital camera time is correct, and the same as the on on the GT-200E, take both your camera and the GT-200E with you. When you’re back home, the software will be able, based on picture time, to insert GPS coordinates into EXIF metadata.

  • EXIF is a standard (see specifications HERE), abbreviation for Exchangeable Image File Format, is a metadata format developed by the Japan Electronic Industry Development Association (JEIDA) that is closely associated with JPEG. Most camera users know that it contain some information like aperture, shutter speed, white balance, and flash use.

    The software will add GPS data into each of your EXIF pictures. A nice feature also built in @trip PC is the ability to export your pictures to Flickr, Picasa and Google Earth/maps or to the Mobile Action online community @Trip

    Travel and Sport logging

    Depending on the kind of travel you are going to do, it is mandatory to connect the i-gotU  200E to an USB port for configuration


    Then you can based on profile usage, fine tune (manual mode) or not the tracking interval. It is basically setting how often you would like the GPS to record your position. Most of the time, you can use the following triggers:

    • Based on time, every X seconds, a new GPS point will be saved,
    • Based on speed, starting at speed X, a new GPS point will be saved,
    • Both of the above.

      The objective of all these settings is to avoid recording too many points, and as such flooding the internal memory with redundant positions. The graphical user interface is very intuitive, and quite pleasant to the eyes as seen in the screenshots below:

      Slow walking tracking mode

      configuring.03 configuring.04
      Bicycle and scooter tracking mode
      configuring.05 configuring.06
      Boat and car mode
      configuring.07 configuring.08

      Your device is now ready, depending on the recording speed, you may use it up to 80 hours.

      Importing data back

      To import you data back in the software, just connect your i-Got-U 200E to your PC. The software will ask for a name and then display your travel path in Google Maps. Below is a screenshot of a travel from Zurich to St Gall by train.


      Export functions are just a click away


      You can easily export to

    • @trip online community server,
    • MHT a single file that contains an HTML page, pictures and JavaScript imitating the @Trip PC interface,
    • KML is a file format used to display geographic data in an Earth browser such as Google Earth, Google Maps, and Google Maps for mobile.
    • KMZ are just zipped KML files.

      Presentation of portal @trip

      The community portal is located at and registration is free. It offer you a way to share your picture online along with your recorded GPS tracks.


      There is some tutorials online and an active forum


      The i-gotU GT-200E is one of the most accurate tracking devices I’ve ever tested. The unit uses the same high-performance GPS receiver found in other SiRF’s 20-channel Star III receiver (Accurate to within about 5 meters).  The i-gotU GT-200E use SiRF’s high performance GPS receiver for enhanced positioning indoors where GPS signals cannot penetrate, and Google Maps/Earth is a powerful combination that let you appreciate the  devices accuracy, ease of use, and reporting capabilities. I consider the price also to be quite cheap. The device itself sells online for around (59€ or 89 CHF), money well spent if you have a serious need to track/geo tag your pictures, compare to other proprietary GPS solution from Nikon GP-1 (152€ or 229 CHF) or Canon 3rd party hardware.


  • The i-gotU GT-200E is a durable, lightweight, water-resistant tracking device that works spectacularly well both indoors and outdoors.
  • Extremely accurate SiRF Star III 20-channel receiver,
  • Works inside buildings, movie theaters, basements,
  • Easy to use setup, applications and use of the web portal,
  • Location reports can be viewed from any web browser with Internet access,
  • Google Earth/Google Maps provide visually stunning location reports,
  • Device can record location/altitude data every x seconds ,
  • Small size, power up and forget,
  • Water protective casing, a plus for any outdoor photographers,
  • Self-contained, requires no installation,
  • Huge memory storage: enough for 80 hours of recording or 262.000 points,One the easiest interface to geo tag your pictures (I did use RoboGEO in the past)



    • Proprietary USB power cable, better not loose it
    • Accuracy of battery life indicator (a blinking led)
    • An OLED screens would have been great to watch the internal status of memory or to switch from tracking point mode. But very few devices on the market are proposing such features anyway.


      At this level of price versus functionalities, the choice is quite limited but you may want to consider other model from the same brand


      i-gotU GT-120 (39 € or 59 CHF)


      Where to buy?

      i-Got-U GT-200E  is manufactured by Mobile Action and available for purchase at various retail and online stores.
