Detailed Description

Evaluate the geomagnetic variables (latitude, longitude, McIlwain L, B field) for any point in orbit. Specialized for a low-inclination circular orbit at altitude 600 km.

Method: Linear interpolation in tables with a 5-degree grid. Latitude values between -30 and + 30 degrees. Data values obtained from the GSFC programs BILCAL and GEO_CGM.

Latitudes and longitudes are both expressed in degrees.

Patrick Nolan, Stanford University First written February 2000.
