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

• breadboard assembly of components
• record GPS traces in memory and SD card
  • battery powered data logging (temperature not GPS)
  • battery powered GPS logging
• 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.
