An automobile has a system for navigating using a vehicle speed sensor reading rotation data from a wheel and a gyroscopic sensor. For each of a plurality of error parameter values, a distance traveled for each of a plurality of directions of travel. The system also includes selecting the error parameter value that maximizes the distance traveled in one or more of the directions of travel, applying the selected error parameter value to data from the gyroscopic sensor, and navigating using dead reckoning based on data from the vehicle speed sensor and data from the gyroscopic sensor with the applied error parameter value.

A satellite navigation method and system are provided. The system includes a global position system module, an input unit, a picture database, a geographical information system module, an integrating unit, and a display unit. The method includes the following steps. Firstly, a navigation area is determined through the input unit, so as to search out several picture batches in the navigation area from the picture database. Next, a map relating to the navigation area is provided by the GIS module. Then, the picture batches and the map are integrated by the integrating unit to produce an integrated map shown on a first frame of the display unit. Afterwards, several pictures of the picture batch chosen from the first frame displayed on a second frame and satellite navigation information of the picture chosen from the second frame are displayed on a third frame by the display unit.

Interfacing application programs and motion sensors of a device. In one aspect, a high-level command is received from an application program running on a motion sensing device, where the application program implements one of multiple different types of applications available for use on the device. The high-level command requests high-level information derived from the output of motion sensors of the device that include rotational motion sensors and linear motion sensors. The command is translated to cause low-level processing of motion sensor data output by the motion sensors, the low-level processing following requirements of the type of application and determining the high-level information in response to the command. The application program is ignorant of the low-level processing, and the high-level information is provided to the application program.

Systems and methods related to gyroscope related applications. A platform having at least one toms shaped channel that is filled with a liquid is used in conjunction with at least one marker to determine the direction of forces applied to the platform. Each marker is neutrally buoyant within the liquid and a marker tracking system is used to determine the displacement of the marker from its resting place after a force has been applied to the platform. The tracking system may be based on at least one digital camera in conjunction with suitable image processing software to determine the marker's position before, during, and after the force has been applied. A gyroscope can be constructed using three such platforms with each platform being orthogonal to the other two. Each platform may have multiple concentric channels with a common center with each channel having a different sensitivity to the applied forces.
