LocalEarthRadius
[re,NSre,EWre] = LocalEarthRadius(G) [re,NSre,EWre] = LocalEarthRadius(R1,[R2],[re])
Computes the effective spherical Earth radius as function of latitude.
|
Parameters |
Description |
|
G [struct] |
Geometry structure from GeomStruct or a comma-separated list of (R1,[R2],[re]) |
|
R1 [Nx3 vector] |
LLA position vector 1. |
|
R2 [Nx3 vector] |
(Optional) LLA position vector 2. Can be empty but must be passed if passing re. If not passed in or passed in as empty, re is (NSre+EWre)/2. |
|
re [vector] |
(Optional) 2 element vector, [Equatorial radius, Polar radius], of the geodetic earth radii (m). Defaults to [6378137, 6356752.314] from PhysicalConst. |
|
Return Values |
Description |
|
re [vector] |
Vector with same dimension as R1 & R2 with the effective spherical Earth radius (m). |
|
NSre [vector] |
Vector with same dimension as R1 & R2 with the effective North/South spherical Earth radius (m). |
|
EWre [vector] |
Vector with same dimension as R1 & R2 with the effective East/West spherical Earth radius (m). |
