Ellipsoid definition
Ellipsoid Semi-major axis given in meters
Reverse flattening of the ellipsoid, 1/f
Online base station coordinate calculation tool: input the geocentric-fixed coordinate XYZ of the rover station or the geodetic coordinate LBH of the rover station, input the ENU coordinate of the rover station relative to the base station, and calculate the XYZ or LBH coordinate of the base station. This tool supports batch calculation and multiple ellipsoids.
Online base station coordinate calculation tool: input the XYZ or LBH coordinates of the rover station, as well as the ENU coordinates of the rover station relative to the base station, to calculate the base station coordinates.
- Rover Station Coordinate : Input the coordinates of the rover station, supporting the input of Earth-Centered Earth-Fixed XYZ coordinates or geodetic coordinates LBH. Up to 100 sets of rover station coordinates can be inputted. The XYZ coordinate unit is in meters, the LB unit is in degrees, and the H unit is also in meters.
- Rover ENU Coordinate : Input the ENU coordinates of the rover station relative to the base station. The unit of ENU coordinates is meters. Up to 100 sets of ENU coordinates can be inputted.
- Rover Coordinate Type : Select whether the input rover station coordinates are in XYZ coordinates or LBH coordinates.
- Ellipsoid : Select or customize an ellipsoid.
- Base Coordinate Type : Select the type of base station coordinates to output, supporting XYZ and LBH.
- Algorithm : Select simple calculation or iterative calculation. When the baseline length is less than 10 kilometers, simple calculation is sufficient, and the error can be ignored. When the baseline length is greater than 10 kilometers, it is recommended to choose an iterative calculation algorithm. Simple calculation using the latitude and longitude of the rover station as the latitude and longitude of the base station for approximate calculation, suitable for short baseline scenarios. Iterative calculation uses the latitude and longitude of the rover station as the initial value for the latitude and longitude of the base station, and performs multiple iterations until the radian value of the latitude and longitude change of the base station is less than 1e-6. Iterative computation is suitable for long baseline scenarios.
