GPSArea measuring instrumentIntroduction:

At the request of our customers, our company has developed a handheld computer area tester based on the existing ordinary area meterKM-2This area meter has high precisionGPSThe combination of positioning system, precise area calculation method, and intelligent handheld computer system * enables real-time testing of any irregular area, dynamic graphic display, and intelligent processing and storage of data. One measurement can simultaneously obtain data such as measurement area, perimeter, distance, slope area, etc. The measured area graph and all measurement data can be accessed at any time for easy archiving. In addition to measuring area, it is also a powerful entertainment car navigation system with functions such as audio playback, movie playback, and gaming

Having an area meter allows you to enjoy the fun of work, entertainment, and life!

GPSPrinciple of Area Measuring Instrument:

GPSThe area measuring instrument adoptsGPSSatellite positioning systems can provide real-time navigation and positioning information such as longitude, latitude, elevation, etc., utilizingGPSThe positioning function obtains the coordinates of each point, and then calculates distance, area, and other data through mathematical methods. due to grounds ball It is an ellipsoid, and in order to accurately calculate distance or area, it is generally converted into plane coordinates through projection.In China, large-scale maps are usually converted using Gaussian Kruger projection. However, the projection method is very complex to calculate and difficult to implement in microcontrollers.To simplify the calculation, we consider the Earth as a regular sphere. Land acquisition ball Radius is6371116m, can be converted into plane coordinates:
Where:RFor the radius of the Earth,xFor longitude/m,yFor latitude/m.
standard exist grounds Ball surfaceYLongitude, longitude difference, latitude difference
The area of each square is one degree:
