Navigation device with adjustable data transmission

摘要

A navigation device for determining the location of the device includes a location determining module to generate data relating to a geographic location of the device, and to adjust frequency of transmission of the data over a communication interface based on a selectable threshold value representing an amount of change in the geographic location of the device.

1. A system for determining the location of a navigation device comprising:
a navigation device, comprising: a location determining module comprising hardware and logic to: generate first data relating to a first geographic location of the device based on a first received navigation data; generate second data relating to a second geographic location of the device based on a second received navigation data; receive a user input corresponding to a threshold transmission value representing a frequency at which the first geographic location is to be transmitted over a communication interface,
wherein the communication interface provides power to the navigation device; calculate a change in a geographic location of the device based on a difference between the first generated data and the second generated data at the device; and transmit the second generated data over the communication interface when the calculated change in the geographic location of the device exceeds a threshold geographic change value representing an amount of change in the geographic location of the device, wherein the threshold geographic change value is selectable from a plurality of threshold geographic change values; and a host computing device in communication with the navigation device, comprising a GPS device driver to allow a data stream application to communicate with a host universal serial bus controller, wherein the data stream application is to receive a constant stream of data including data relating to the first geographic location of the device from the GPS device driver; when there is no change in the geographic location of the device and when there is a change in the geographic location of the device.
