In order to obtain the correct map data, NDrive and its map suppliers,TeleAtlas, rely on local government and other local organizations across the whole of Europe to supply us with the correct, relevant and most up to date information for millions of roads, streets and lanes.

There are only a few map suppliers in the world that have good map data, one of them being TeleAtlas. On average, 5% of all European roads are changed; our map supplier has hundreds of people driving through Europe and analyzing satellite images to register these changes. This process is time consuming and a logistical challenge. This is also the case for all map feedback our NDrive customers submit via our website. These map reports are passed on to our digital map suppliers, who will then in many cases, physically visit the location to register a different situation.

Digital map data is a rapidly growing market. Thousands of kilometers of roads are added every year next to the 5% of changes that are being made. Still the coverage of the map data, in almost all western European countries, is more than 99%. There are still exceptions possible, but the digital map data NDrive is using at present is the best data available on the market. Next to having the best map data it is also the latest map data available.

Our map data has a version number and a date, the date represents the time when the analyzing of the roads freezes and the map supplier starts updating the map data. When the updating has finished NDrive will start the compressing process, in order to fit the map data on a reasonable size memory card. This takes time and therefore the date is always older than the release date of the map data.

When flight mode is enabled on some devices, Bluetooth is switched off. This means that you can no longer connect to a Bluetooth GPS unit. To get a connection, switch off flight mode and start the NDrive application again. TOP ------------------------------------------------------------------------------------------------------------------------------------ What is GPS? The Global Positioning System (GPS) is a satellite-based radio navigation system developed and operated by the U.S. Department of Defense. GPS permits land, sea, and airborne users to determine their position, velocity and the time 24 hours a day, in all weather, anywhere in the world. The GPS signals are available to an unlimited number of users simultaneously. The GPS satellites can be used free of charge by anyone.  TOP ----------------------------------------------------------------------------------------------------------------------------------- How does GPS work? Each GPS satellite transmits signals to equipment on the ground. GPS receivers passively receive satellite signals; they do not transmit. GPS receivers require an unobstructed view of the sky, so they are used only outdoors and they might perform less well within forested areas or near tall buildings. GPS operations depend on a very accurate time reference, which is provided by atomic clocks at the U.S. Naval Observatory. Each GPS satellite has atomic clocks on board. The Global Positioning System (GPS) uses a network of satellites which let people with GPS receivers pinpoint their location anywhere in the world. NDrive makes GPS technology available in an easy-to-use form for everyone. TOP ---------------------------------------------------------------------------------------------------------------------------------- How does NDrive use GPS? NDrive develops the latest navigation software to bring GPS data and up-to-date map information together in a way that works perfectly with today's portable devices. Note: some athermic heat-reflecting windscreens and built-in windscreen heaters block GPS signal reception inside the car. TOP ---------------------------------------------------------------------------------------------------------------------------------- What can cause GPS signal errors? Factors that can degrade the GPS signal, and thus affect accuracy, include the following: • Ionosphere and troposphere delays : The GPS signal slows as it passes through the atmosphere. • Signal multipath : The GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver. • Orbital errors : Also known as ephemeris errors, these are inaccuracies of the satellite's reported location. • Poor satellite visibility : The more satellites a GPS receiver can "see", the better the accuracy. GPS units typically will not work indoors, underwater, or underground.

TOP ------------------------------------------------------------------------------------------------------------------------------ NDrive GO FAQ  What is the best place on the windscreen to mount my NDrive GO? NDrive GO should be placed in a position on your windscreen that does not block your view of the road in any way and enables an optimal usage of your device. Our advice is to mount your NDrive GO at the lowest possible position on your windscreen. Your device should not be placed directly under your rear-view mirror. With the alternative mount kit it is possible to mount your NDrive in many other positions like attached to your dashboard or ventilator. Some athermic heat-reflecting windscreens and built-in windscreen heaters block the GPS signal reception inside the car. Very often, such heat-reflecting windscreens have a hole behind the rear-view mirror or the heat reflection is limited on the left (or right) side of the windscreen to let signals pass through. If you can not get a signal, use the external GPS antenna provided (remember: your GPS receiver should always have a free view of sky).
