Positioning at 10Hz update rate

Positioning at 10 Hz update rate (ten times per second) creates more detailed and higher resolution vehicle tracking capabilities. Trails of the vehicle can be recorded with ten times the resolution compared with the more traditional 1 Hz positioning update rate.

[Usage example]

Car navigation system / PND ("Portable Navigation Device" or "Personal Navigation Device") By updating the positions ten times per second, the map can be scrolled more smoothly.
Data Logger Even while driving on the express highway, the trails of the vehicle can be recorded in minute detail to ensure accurate and complete data analysis capabilities.
Drive Recorder (Event Data Recorder) In the event of abrupt steering, braking or a collision while driving, the detailed position where such events take place can be accurately recorded.
GPS Speed Meter Speed of the vehicle can be output 10 times per second. This is a much more detailed speed output compared with the conventional update rate of once a second.
Vehicle-to-vehicle (V2V) communication/ vehicle-to-infrastructure (V2I) communication 10Hz helps automated systems accurately determine the positions of other vehicles nearby even in poor visibility conditions and difficult areas such as intersections or junctions.

Actual positioning data of 10 Hz on a town street in Nishinomiya (Japan)

Below is an example that shows the difference between 1 Hz and 10 Hz position update rate. The vehicle driving at 60km/hour travels 16.7m in a second. Since position update is ten times more frequent, the record of the vehicle's trail is shown much smoother at 10 Hz position update than at 1 Hz position update.
