SAGASAGAA General DescriptionA General Description
• SAGA is a fully self-sufficient unit (apart from being connected to the vehicle’s 12v or 24v power supply via cigarette lighter plug, or hard-wire.)
• SAGA is secured to the top of the dashboard via Velcro or a suction cup.
• SAGA has an internal GPS receiver.
• After use, SAGA is removed from the vehicle and the unit’s telltale information is downloaded into a computer.
• A wireless option will be available end of summer 2003.

What does it do?What does it do?
SAGA measures, lists and documents all principal elements of driving behaviour.
It logs:
• Speed (allowed speed intelligence).• Acceleration.• Deceleration.• Centripetal acceleration (indicates G-force in turns)
• Route travelled (displayed on a road map)
• Travelling time.• Position, time, date and duration of each stop.• Distance travelled (total and/or partial).
www.nd.is
Evidence is presented
in a summary reporting :
• Speeding
• Speed category
• Unwise acceleration
• Unsafe deceleration
• Unsafe G-force in turns
• Driving time
• Stops (number and duration)
• Distance
