Tracking API JSON

The Tracking API stores data as JSON with one document per message.

The JSON documents share a common structure, but details vary between different tracking technologies.

Examples

• Argos DS (type = ds)
• Argos DIAG (type= diag)
• [Argos XML] (coming)

latitude -39.667 Latitude in decimal degrees [-90..90]

longitude 176.896 Longitude in decimal degrees [-180..180]

altitude Altitude in m,

technology Tracking technology ("argos"|"iridium")

type Input data type, for Argos this is "ds"|"diag"
