ROADMAP

[betatim]

Where are we headed?

Vision or very long term goal

A open-source platform that can be used for humanitarian GPS tracking and logging. hackable, low cost, and robust.

This roadmap is organized into stages of development, leading towards a field tested design that can be extended for new needs.

Stage 1

• [x] breadboard assembly of components
• [ ] record GPS traces in memory and SD card
  • [x] battery powered data logging (temperature not GPS)
  • [ ] battery powered GPS logging
• [x] simple REST end point to upload data to
• [ ] first iteration of a case to house components
• [ ] tools to overlay traces on existing maps
• [ ] define data format

Stage 2

• [ ] record GPS traces for short time (~2min) and then sleep for a long time (10min)
• [ ] second iteration of case
• [ ] less simple REST end point to upload data to (identify individual devices, JSON API)
• [ ] combined power supply using 12V motorbike power and a battery

Stage 3

• [ ] broadcast recorded GPS points when near a friendly WiFi AP
• [ ] server that receives GPS points, can display them and export to other formats

Stage 4

• [ ] add GSM module to transmit location every N minutes
• [ ] server that listens for text messages and records them

Have you thought about using Low-Power Wide-Area Network (LPWAN) like LoRa or Weightless? You could use this when there is no GSM coverage.
