Enhanced Positioning Technology

Note: Enhanced Positioning Technology is available on the TomTom GO 930

and 930T.

Enhanced Positioning Technology or EPT estimates your location when GPS

reception is poor, such as when you drive between tall buildings.

Your GO uses positioning sensors to monitor your acceleration and direction

and then estimates your current location.

EPT only helps your GO to estimate your location. Calculating your precise

location is only possible when your GO receives a strong GPS signal.

When your GO is using EPT to estimate your location, the EPT icon is shown

on the status bar.

Your GO calibrates EPT automatically. If calibration is not complete when your

GO loses GPS reception, EPT cannot be used and the screen is shown in grey,

for example, when there is no GPS reception at the beginning of a journey.

Calibration

Calibration is done automatically and requires no interaction from you.

However, it is useful to have basic understanding of the calibration procedure.

Your TomTom GO resets the positioning sensors each time the device is

switched on. To help improve accuracy in estimating your location, your GO

calibrates the sensors throughout your journey.

The following conditions are required for successful calibration:

• Your GO is receiving a strong GPS signal.

• The car has been stationary for at least 5 seconds and then travels along a

straight and level section of road for at least one minute.
