How does a GPS receiver work?

A microprocessor within a GPS receiver uses these delays and the position of the satellite to calculate the distance to each satellite, and then uses this information to determine location through triangulation.

Why do GPS receivers use the almanac?

GPS receivers use the almanac to determine the position of the satellites. Minor variations in the orbits of the satellites occur due to gravitational forces from the sun and the moon. The DOD continuously monitors the satellites and adjusts the almanac information to represent the actual orbits of the satellites.

What is the format of GPS coordinates?

GPS receivers can usually report position information in more than one format. The most common format is lat/lon (latitude and longitude). Lat/lon coordinates are recorded in angular units of degrees, minutes and seconds. One second of latitude is equal to about 30 meters. GPS receivers may display lat/lon in degrees plus minutes to four decimal places (instead of minutes and seconds). Most geographic information system (GIS) software is capable of using more than one format and may automatically convert lat/lon coordinates to a coordinate system such as Universal Transverse Mercator (UTM) or State Plane Coordinates (SPC) to calculate distances in meters or feet.

How many miles are satellites orbiting around the Earth?

Orbiting around the earth at an altitude of 12,550 miles, these satellites are in predictable locations; hence, we refer to the system of satellites as the GPS constellation.

What is triangulation in GPS?

Triangulation is a mathematical method for locating points on a plane in three-dimensional space. If the distances to each of three satellites and your approximate location on the earth are known, the GPS receiver can calculate its terrestrial position.

Why are coordinate systems important?

Several coordinate systems are in use for mapping and may cause problems with compatibility between software systems. Users frequently need to transform position data into a plane (flat) coordinate system, either to merge them with another data set, to plot a map of the GPS results, or to perform further calculations for such parameters as area, distance or direction (plane coordinate systems are usually easier to work with than geodetic coordinates). When using data and maps from several sources, coordinates must be based on the same datum. The coordinate system differences, which are caused by a different reference frame, ellipsoid and data adjustment, are significant (up to several hundred meters) and cannot be ignored.

What is GPS in farming?

The Global Positioning System (GPS) provides opportunities for agricultural producers to manage their land and crop production more precisely. Common names for general GPS applications in farming and ranching include precision agriculture, site-specific farming, and prescription farming. GPS applications in farming include guidance of equipment such as sprayers, fertilizer applicators, and tillage implements to reduce excess overlap and skips. They can also be used to precisely locate soil-sampling sites, to map weed, disease, and insect infestations in fields, and to apply variable rate crop inputs and, in conjunction with yield monitors, record crop yields in fields.

What is GPS used for?

GPS technology is used to locate and map regions of fields, such as high weed, disease, and pest infestations. Rocks, potholes, power lines, tree rows, broken drain tile, poorly drained regions, and other landmarks can also be recorded for future reference.

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.

Why do satellites use clocks?

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.

Why is GPS important in agriculture?

The reason that everyone has a vested interest in the efficiency of the American and global farming industry is that the more efficient farmers are, the more crops they will be able to produce. If crop yields are maximized to the outer limit of their potential, the end result would likely be a reduction in the cost of food. People spend less money at the grocery store and then have the extra disposable income to spend elsewhere and stimulate the economy. Clearly, it would be difficult to find someone who could find a real reason why it would be wrong to increase crop yields, but actually making that happen is a challenging task for the farmers who already utilize almost all the tools available to their disposal. This is where GPS vehicle tracking systems can help when it comes to the process of agriculture asset management.

How does GPS help farmers?

Farmers everywhere are utilizing GPS tracking and navigational equipment to help determine what areas require fertilizer and how much fertilizer needs to be dispensed. Although it may appear at first glance like a very simple chore when a farmer has to maintain an area of land that is over 4,000-acres large or bigger the situation can be strenuous. The advanced farming techniques that use heavy machinery, navigation, and tracking system technology have all helped farmers across the United States increase corn yield, and nothing could make it more evident than the fact that Ohio recently set a new record for production of corn while working with fewer acres of land and fertilizer.

What is the best GPS tracking system for farming?

GPS tracking systems are great tools for farmers because the units can both provide a way to quickly recovery expensive farming equipment if it were ever stolen, and enhance the efficiency of farmers working in the fields. From the theft protection aspect, farmers who equip live GPS trackers such as the SilverCloud tracker to their farming equipment can have constant remote access to their expensive machinery, but that is not the best part. The best part about using sophisticated agriculture asset trackers like the SilverCloud GPS is that the devices can actually alert farmers if their equipment is moved by sending a text message or email alert. Farmers can rest easy knowing that their farming equipment is safe when they use agriculture asset management technology. Not to mention, the rugged GPS trackers are often waterproof and engineered with magnetic surface mounts so they can be covertly placed on any piece of farm equipment to boost anti-theft security!

Why was real time GPS tracking important to farmers?
