OMEGA

Description

This program

• Calculates the angular velocity of a body's rotation by using the position of landmarks in subsequent images

The images should be at least roughly registered (REGISTER) before starting

Required Files

• OMEGA.TXT which has an initial guess for the RA/DEC of omega and its magnitude in deg/da.
• PICTLIST.TXT
• LMRKLIST.TXT

Inputs

• The image name of two images that have some common landmarks in them

Outputs

• OMEGA_SUM.TXT - Inertial space RA/DEC of omega, Inertial space RA/DEC of body frame z-axis, and the LAT/LON of the omega vector in the body frame

Using OMEGA

Here is a sample of the standard input:
