BLACKSPOT
Police and Local Authority designated repeat accident areas - take
extra care
GPs
Utilising the latest Global Positioning Satellites (GPs), a powerful
internal aerial identifies the precise location, speed and direction
of your vehicle.
ADVANCED WARNING
When approaching a known danger zone, the LCD display turns from green
to red and the type of danger is highlighted. The bar counter starts
to count up as the danger area gets closer. An audible tone is emitted,
the frequency increasing with proximity. Once the location is passed
the unit returns to standby.
EASY UPDATES
With the number of speeding cameras set to dramatically increase and
accident data changing constantly, Blackspot Interactive are constantly
working to verify new locations and delete obsolete ones. These changes
are easily updated to your ROAD ANGEL with the supplied software.
The first year of updates is free of charge with an annual subscription
thereafter of £49.
PERSONALISATION
The standard settings can all be user adjusted. New locations can
be stored, current locations deleted, warning range and volume adjusted
or muted and various other features. |
TECHNICAL INFORMATION
GPs is a group of 24 satellites each orbiting the earth at around
11000 miles above the surface. Each Satellite circumnavigates every
12 hours. At all times at least four satellites will be in view at
any given point on the globe. GPs has been fully operational since
1990.
Since the scrambling on the civilian GPs channel accuracy has greatly
increased.
Road Angel has a 12 parallel channel GPs engine with a built in active
antenna. As long as Road Angel can see a minimum of 3 satellites then
an accurate position of the vehicle can be calculated. Road Angel
checks its position every second and is able to work out accurately
the speed of the vehicle. Road Angel can store up to 50,000 unique
locations.
Road Angel constantly compares its position with the stored database.
When nearing a stored location the unit gives an audible and visual
alert. Road Angel uses complex heading software so it alarms only
in the direction the camera faces.
As with all GPs technology, when Road Angel is first powered it must
acquire satellites to know its position. The first start is known
as a cold start which can take up to 45 minutes to acquire the minimum
three satellites for correct operation. Thereafter, warm starts (when
the unit has been switched off overnight) should take a matter of
minutes and hot starts (same day) a few seconds. When the unit has
acquired satellites the display will show speed.
If after this period of time the unit is still not showing speed,
reposition the unit where it will have a better view of the sky. You
can check to see how many satellites it has acquired by scrolling
through to the 'sat' menu. |
