    Tags: rechargeable battery, temperature

    MetaGPS is designed for outdoor people. We expect our customers take this product to remote locations around the world. When we design the product, we want the product to work in those remote locations. The temperature ranges from -20 C to + 60 C. All parts in the MetaGPS will be fully functional in this temperature range.

    I had a friend who is an avid hiker. He mentioned that the temperature up in the mountains can reach -40C. I expect all the components in MetaGPS will work in -40C with exception of the rechargeable battery. The specification for battery is to work from -20 to +60 C. I expect it will work in -40C but with less capacity.

     
  • Electronic compass with 3 axis

    Tags: 3 axis,

    Received an email asking if our product M2 uses 3 axis electronic compass which records heading tilt and tip.

    Our M2 currently uses a 2 axis electronic compass which it uses x,y coordinates to calculate the headings. It can only record heading information. Technically, it is not that difficult to uses a 3 axis electronic compass. We need to make some changes in the electronic circuit and modify the control software.

    However, as far as we know, the Nikon DSLR does not record the tilt and tip information to be embedded into the picture EXIF file. So, we will not work on the 3 axis electronic compass as of now.

     
  • The M2 (with electronic compass) engineering sample is finished.

  • MetaGPS Development Blog

    After working on this product for sometime, I decided to start a development blog for two purposes:

    1: To keep track of the development and manufacturing.

    2: To keep existing and potential customers updated on the progress.

     This product grew out of my own passion of traveling and photography. Traveling around the world, I have taken tens of thousands of pictures and when I look back at those pictures, I can not recall where some of them are taken.

    Luckily, Nikon’s DSLR can take in GPS signals and embed them into the picture meta file. All it takes is a little device that receives GPS signals and sends them to the camera.
