IRIS Handheld Iridium Tracker Installation Guide
VG Tracker Set Up
S&G supplies its Client Representatives with global tracking units intended to be operated onboard supported vessels. The units measure GPS positions which are telemetered in real time via Iridium to IRIS, nominally every hour. Position accuracy is generally better than ±5m. The IRIS team can configure most things remotely once initial setup is complete.
