Background Information
About Global Positioning Satellites (GPS)
Operational since 1990, 24 satellites orbit the earth at a height of 11,000
miles. At any given point on the globe, at least 4 satellites are in view at
any one time. Using sophisticated aerials and triangulation techniques,
units such as ROAD ANGEL Vantage are able to compute your position to
within 5-10m.
ROAD ANGEL Vantage may lose the GPS satellite signal temporarily
owing to tunnels, tall buildings, bridges, dense foliage or adverse weather
conditions. When you are clear of the obstruction, ROAD ANGEL Vantage
should re-acquire satellite signals in a few seconds.

Speed Cameras and Hazards
Gatso
The most common type of speed
camera – used in fixed positions
mounted on poles at the roadside.
Measures vehicle speed using
radar and, if the speed limit has
been exceeded, photographs the
rear of the vehicle. Uses a flash unit
inside the camera cabinet or
mounted on a gantry to illuminate
the offending vehicle's rear number
plate. ROAD ANGEL Vantage
relies on up-to-date database
information for detection.
SPECS (Average speed)
Takes a photo of your vehicle at the
‘start’ point and then another a set
distance further down the road. If
your average speed is greater than
the speed limit between these two
cameras you are automatically
prosecuted. ROAD ANGEL
Vantage relies on up-to-date
database information for detection.
Watchman
Measures vehicle speed and, if the
limit is exceeded, takes a photo of
the rear of the vehicle. Can be
accessed remotely allowing
operators to download live video,
stored images or data. ROAD
ANGEL Vantage relies on up-to-
date database information for
detection.
