| What is Lefebure.com GPS? This is a project to build an auto-steer system for agricultural use. More specifically, the system uses GPS data to create a coverage map, and also to steer the machine. The original goal was to build a system that is more intuitive and less expensive than anything else on the market.
| Current Status: | Development | | GPS Antenna Simulator: | Done | | Real NMEA input via RS-232: | Done | | Client / Farm / Field / Load Names: | Done | | Tractor Dimensions: | Done | | Implement Dimensions: | Done | | Ariel & Perspective View: | Done | | Pattern / A-B Line: | Done | | Software to Hardware Control: | Done | | Electro/Hydraulic Steering: | In testing. |
But Why? Frankly, I think I can build a better mouse trap. An auto-steer system has to get data from a GPS receiver, process that data, and send electronic commands to some steering control system. All of the magic happens where the GPS data gets processed. Most everything on the market today uses proprietary hardware and software to accomplish this. I will be using a standard Windows computer to do this (laptop, tablet PC, mobile PC, etc.) which will reduce costs, allow the operator more flexibility, and the hardware can be used for other purposes in the off season. The screens are bigger, wireless networking opens a few doors that aren't even being thought of now, Internet access while in the field has some benefits, and the list goes on.

| GPS Antenna Simulator: | This program simulates a GPS antenna by generating NMEA standard $GPRMC codes and sending them out a serial port. Requires a null modem cable to some other device. Requires Windows 2000 or above and the .Net Framework 2.0 or above.
