Convert ECI to ECEF Coordinates
Transform ECI position, velocity and acceleration to ECEF position, velocity & acceleration.
Convert Pseudo Earth Fixed Inertial Coordinates to ECEF Coordinates. This function has been vectorized for speed.
Example Function Call:
>> [r_ECEF v_ECEF a_ECEF] = ECItoECEF(JD,r_ECI,v_ECI,a_ECI);
Where:
JD is the Julian Date vector [1 x N] (units are in days)
r_ECI is the position vector [3 x N] (any units are permitted)
v_ECI is the velocity vector [3 x N] (any units are permitted)
a_ECI is the acceleration vector [3 x N] (any units are permitted)

| 版本 | 已发布 | 发行说明 | Action |
|---|---|---|---|
| 1.8.0.0 | Clarified that the ECI frame is in Pseudo Earth Fixed Coordinates (No Nutations are performed about the +Z axis for speed) |
||
| 1.7.0.0 | Updated mean obliquity of elliptic equation to be consistent with units. All units in this equation are in degrees. |
||
| 1.5.0.0 | Added another code attachment since the last attachment didn't appear to make it through. |
||
| 1.4.0.0 | Updated vector inputs and outputs to include the acceleration term. |
||
| 1.1.0.0 | Added acceleration transformation update to code. This now supports all position, velocity and acceleration vectors. |
||
| 1.0.0.0 |
