Benefits of technology

This patent describes a navigation system for vehicles that uses different sensors to determine their location accurately. It includes two types of units: one measures both the distance from each other and the direction it travels; while another measure its orientation. By comparing these measurements, the system can identify which car is located within the range between them. Based on this information, the system generates instructions or moves accordingly.

Problems solved by technology

The technical problem addressed in this patent text relates to improving the reliability of navigational systems in vehicles, particularly in terms of ensuring accurate data transmission even if there are temporary losses in communication between them.

Embodiment Construction

[0023]The illustrative embodiments recognize and take into account one or more different considerations. The illustrative embodiments recognize and take into account that a navigation system may involve one navigation system being a master navigation system while the other navigation system is a slave or secondary navigation system. The master navigation system identifies its position. This identification of the location may have some error based on the manner in which global positioning system satellite signals are received. However, the secondary navigation system may use the same error correction as the master navigation system such that a desired level of accuracy is present in identifying the location between two vehicles.

[0024]The illustrative embodiments also recognize and take into account that when communication is lost, the secondary navigation system is unable to obtain navigation information such as the position of the master navigation system and error correction informati

Abstract

A method and apparatus for managing movement. A navigation system comprises a first inertial measurement unit enabled global positioning system device having a first inertial measurement unit with a first level of accuracy in a first vehicle and is configured to provide first information that identifies a position of the first vehicle relative to a second vehicle. The navigation system further comprises a second inertial measurement unit enabled global positioning system device in the first vehicle having a second inertial measurement unit with a second level of accuracy that is greater than the first level of accuracy and is configured to provide second information that identifies the position of the first vehicle relative to the second vehicle. The navigation system further comprises a controller that is configured to perform an action based on a desired level of accuracy of the first information.
