What is WAAS system?

The Wide Area Augmentation System (WAAS) differential correction system uses a network of 25 ground-based reference stations. The U.S. Federal Aviation Administration operates the WAAS differential correction service to provide accurate GPS positions for commercial aircraft. The reference stations relay GPS-determined locations to a master station. The master station calculates a correction factor that is transmitted to geostationary satellites (Figure 8). WAAS-enabled GPS units receive the corrected signal from the WAAS geostationary satellite. The WAAS system uses two geostationary satellites located over the East and West coasts of the United States.

How does a lightbar guide work?

Lightbar-guided and automated steering systems help maintain precise swath-to-swath widths. Guidance systems identify an imaginary A-B starting line, curve or circle for parallel swathing using GPS positions and a control module. The module takes into account the swath width of the implement and then uses GPS to guide machines along parallel, curved, or circular evenly spaced swaths. Guidance systems include a display module that uses audible tones or lights as directional indicators for the operator. The guidance system allows the operator to monitor the lightbar to maintain the desired distance from the previous swath. Guidance systems require two principle components: a lightbar or screen, which is essentially an electronic display showing a machine’s deviation from the intended position, and a GPS receiver for locating the position (Figure 1). This receiver must be designed for this purpose and it must operate at a higher frequency (position calculations are usually 5 to 10 times per second) than a GPS receiver designed to record positions for a yield monitor. GPS receivers designed for guidance can be used in conjunction with a yield monitor or for other positioning equipment. Automated steering systems integrate GPS guidance capabilities into the vehicle steering system. Automated steering frees the operator from steering the equipment except at corners and at the ends of fields. Guidance systems base prices are approximately $3,000, including the GPS receiver and a readout unit. Systems that steer the vehicle will be higher priced.

How do GPS coordinates work?

Most maps and globes display longitude and latitude or some other coordinate projection information. Points on Earth are given unique addresses on maps using specific coordinate systems. Agriculturists commonly use either a geographic system of latitude and longitude measured in degrees or a Universal Transverse Mercator coordinate system that locates positions in meters measured from a specific point. The GPS system uses measured distances to the precisely located GPS satellites to locate positions on Earth . Radio receivers in GPS units monitor radio signals broadcast from the GPS satellites. A GPS position is determined by simultaneously measuring the distance to at least three satellites. The distance to a satellite is measured by the time it takes a radio signal to travel from the satellite to the GPS receiver. Computers in GPS units use information from the radio signals, including broadcast time and unique satellite information, to calculate positions. Information from at least four satellites is needed to calculate elevation. Signal reception from more satellites increases position accuracy. The global positioning system includes a constellation of 24 systematically arranged satellites orbiting Earth in six orbital planes with four satellites in each plane. The satellite orbits are approximately 12,500 miles above Earth. The constellation is arranged to guarantee radio reception from at least four satellites from any location anytime, anywhere on Earth (Figure 3). GPS receivers normally receive signals from eight to nine satellites in location without obstructions such as buildings or trees.

How much does a GPS cost?

GPS units for precision agriculture applications require sub-meter accuracy, must incorporate differential correction, and are priced from approximately $1,500. Handheld GPS units without differential correction locate positions within about a 30-foot radial area and range in price from less than $100 to many times that amount. Some handheld GPS units are available with differential correction. RTK GPS systems cost several times as much as common sub-meter accuracy GPS unit used in agriculture.

How does GPS affect accuracy?

The quality of GPS units and operational errors associated with the GPS system determine the accuracy of GPS-located positions. There are several sources of GPS errors. GPS radio signals can “bounce off” objects such as buildings and trees prior to acquisition by the GPS receiver, resulting in lower accuracy. This is called multipath error. (Figure 4). The satellites use very accurate atomic clocks to generate the timing data received by the GPS receivers. However, even small errors in timing from clocks in the satellites and GPS units cause errors in GPS positions. Signal delay errors can be caused by atmospheric interference such as electrically charged particles in the ionosphere. A layer of water vapor located below the troposphere can also alter the speed of travel of radio signals. Errors from GPS satellites’ orbit and location are also significant. Pressures from solar radiation and gravitational forces of the sun and moon can alter satellite locations. GPS receiver quality also affects GPS accuracy. More costly GPS units generally provide more accurate GPS positions than less expensive units.
