Syntax

void RPosCalcVector(double lat,double lon,double mag,double azm, double *clat,double *clon);

Header

superdarn/calcvector.h

Library

rpos

Description

The RPosCalcVector function calculates the end point of a vector.

The argument lat and lon give the start point of the vector. The magnitude and azimuth and are given by the arguments mag and azm.

The latitude and longitude of the calculated end point are stored at the locations pointed to by the arguments clat and clon.

Returns

None

Errors
