GPS operating principle Using the SD/MMC card

GPS operating principle

The Global Positioning System (GPS) was developed by the American military in the 1970’s.

GPS’s rely on a total of 24 satellites that are orbiting the earth and transmit signals. The GPS receiver uses the time delay between transmission and reception of these signals to calculate its distance to the individual satellites. It can then use this information to calculate its current geographical position.

A GPS receiver needs to receive signals from at least 3 satellites to be able to determine its position. When it receives signals from 4 or more satellites, it is also able to determine its level of elevation above sea level. A GPS is capable of determining its position accurately to within 3 metres.

GPS route guidance: The supplied

cartographic material includes the geographic coordinates of the POIs, streets and towns shown on the Lucca’s screen. The navigation system is therefore capable of planning and calculating a route from a particular starting point to a particular destination.

When the Lucca receives signals from at least 3 satellites, it is able to determine and show its position on the map. This position can then be used as the starting point for planning a route. Since the Lucca checks its position once every second, you can watch your progress on the map.

Using the SD/MMC card

You can use SD/MMC cards with the Lucca for the following:

•To upload navigation data for other

countries (Chapter (“Uploading cartographic material”)

•Play audio files

(Chapter “Music Player”)

•View image files

(Chapter “Picture Viewer”)

SD-/MMC cards can have a capacity of up to 4 GB and must be either formatted to accept FAT 16 or FAT 32 file systems.

Preparation

You can either save files in a directory or subdirectory. You can also save a range of different format files in the same directory. This is because the Music Player will only play audio files and ignore the image files, and the Picture Viewer will only show image files and ignore the audio files.

Audio Files	Image Files

Inserting the SD/MMC card

The SD-/MMC card slot is located on the Lucca’s right side.

➜Push the SD-/MMC card into the slot as indicated by the marking shown on the slot until it engages.

Removing the SD/MMC card

➜Press the Back button to close the MP3

or Picture Viewer .

➜Carefully press the SD-/MMC card into the slot until it is released.

The SD/MMC card will now slightly protrude from the slot. Remove the card.
