Assignee:

Trimble Navigation LTD - Sunnyvale CA

International Classification:

G06F 1700
G06F 700

US Classification:

701 2

Abstract:

A method and a system for remote control of a rover over a long base line is disclosed. The system includes a primary base station (PBS), a secondary base station (SBS), a rover, a primary long line data link between PBS and SBS, and a secondary two-way data link between the SBS and the rover. The primary data link and the secondary data link comprise a long baseline feedback loop that is used to transmit the control data to the rover, to adjust the control data, and to transmit back from the rover to the SBS and to the PBS the collected feedback data.

Abstract:

A centimeter level survey system includes reference base station and rover GPS units connected by a radio data link. Each includes recorders for the storage of raw measurement information including range, phase, cycle counts and time information. The rover unit is typically moved to points of interest during a survey while the base remains over a fixed, and known location. Generally, the base antenna is located to optimize a clear view of the sky. The rover is subject to interruption of the radio data link from the primary reference station. During periods that the rover is initialized and in contact with the primary reference station base station over the radio data link, the rover provides real time centimeter level position solutions to a survey user, otherwise, the rover records its raw measurements in a file that begins with the last valid initialization information and that ends with any newly reestablished initialization information. A post-processor is initialized by transferring the position filter states and covariance matrix of the real-time processor in the rover directly to the position filter of the post-processor, provided that continuous satellite tracking and no carrier cycle slips have occurred.

International Classification:

US Classification:

701213

Abstract:

A method and apparatus for automatic event detection and processing is provided. A positioning system receiver includes a position measurement device and a logging device. The position measurement device is configured to receive and process signals from a positioning system. The logging device is coupled to the position measurement device for recording data received from the position measurement device. The logging device records the data at a current logging rate. The positioning system receiver detects an event via an external sensor or with reference to satellite data, for example. In response to the event, the logging device automatically modifies data logging processing such as the current logging rate. Additionally, to allow a post processing system to go backwards in time relative to the event, the current logging rate may be increased for a predetermined amount of time preceding the occurrence of the event. According to another aspect of the invention, the data logging processing of a survey system, such as a real-time kinematic (RTK) system including a base reference station and a roving unit, may be altered based upon an event.
