Abstract: The present invention includes a system and method to implement Internet Protocol (IP) hosts on an application specific bus without disrupting the application specific bus. In one embodiment, an IP host determines the application specific bus address of a remote device, the remote device having an IP address in addition to the application specific bus address. The IP host formats a message conforming to the application specific bus, the message containing IP data and message identifiers. The IP host transmits the message on the application specific bus. In addition, the IP host negotiates for network access on the application specific bus. A destination IP host receives the message based upon the application specific bus address of the destination IP host and authenticates the message as an IP messages based upon the message identifiers. In addition, the destination IP host extracts the IP data from the message and processes the IP data by a conventional IP network processing protocol.

Abstract: A method of guiding a vehicle in adjacent swaths across terrain that may slope comprising the steps of: (1) determining the tilt of the vehicle with respect to Earth due to a slope of the terrain; (2) determining the position with respect to Earth of a predetermined location that is fixed relative to the vehicle; and (3) using the tilt and position determinations to provide information for guiding the vehicle to prevent gaps and overlaps between adjacent swaths as the slope changes.

Abstract: A system and method of graphical display of survey information in which input survey data is classified as important or less important and the graphical display shows the important data as a point and a solid vector, and the less important data as a point and a stub-vector, such that the display of the less important data does not significantly obscure the display of the important data.

Abstract: A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. Each fleet vehicle has an assigned time slot to transmit its reporting information over a communications network without interfering with transmissions from other vehicles in their own respective time slots. A timing control phase lock loop (PLL) provides precise time synchronization for timing corrections from a global positioning system (GPS) based time reference. A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption.

Abstract: Real time kinematic (RTK) global positioning system (GPS) technology is integrated with precision farming methodologies to provide highly accurate seeding, cultivating, planting and/or harvesting operations. RTK GPS systems are used to control fully or semi-autonomous vehicles in these operations and may allow for precision planting of seeds (e.g., from a seeder equipped with an RTK GPS receiver and related equipment) and/or precision weed removal (e.g., using a vehicle fitted with weed eradication mechanisms such as augers and/or herbicide sprayers). Crop specific fertilizer/pesticide application is also enabled through the use of centimeter-level accurate positioning techniques.

Abstract: A multi-stage process for detecting and excluding faulty measurements in a satellite positioning system receiver are described. Availability of fault detection is evaluated based on satellite geometry and satellite measurement quality. If fault detection is unavailable using only satellite measurements, an additional measurement is used, and fault detection availability is again evaluated. If fault detection is available, detection of a potential fault is performed. If a fault is detected, an exclusion/isolation process is activated. In that case, a fault exclusion operation is tested for availability. If fault exclusion is unavailable using only satellite measurements, an additional measurement is incorporated, and fault exclusion availability is again evaluated. If fault exclusion is available, an attempt is made to isolate and exclude the faulty measurement from a list of satellite measurements used for the navigation solution.

The PBS is placed in a position with a known location. The PBS wirelessly downloads its logged set of data into the Internet server using the (PBS-WIDAD). The SBS determines its precise position coordinates by accessing wirelessly the PBS logged data on the Internet server using the (SBS-WIDAD).
