GPS chip for the near-space mission

GPS chip for the near-space mission

The GPS chip, I ordered has just arrived and am starting the work by tomorrow. I chose a SIRF III based custom built GPS chip from Inventek. The reason behind my choice are as follows.

  1. ISM300F2-C5-V0004 is one among the few commercially available GPS chips that are capable of working up to 42 km high.
  2. Inventek has a very good/polite/caring sales team. I had a big conversation for atleast 20 days with Nancy Rose, who very well knows my order quantity is less than 5 GPS chips. Every email was instant and they gave a good support and recommended the right chip to choose for my purpose.
  3. The chip is really compact than I expected. The size of the chip is 18mm X 18mm x 3mm which is very much smaller than a 1 rupee coin. The power consumption is also rated very low, however I have not tested it yet.
  4. The chip has serial port for communication with flight computer.

Here are some pictures of the chips I received. The other chip slightly bigger than the GPS chip is the GPS antenna that fits to the GPS chip which you can to buy from Inventek.
