WGS 84 is the adopted ellipsoid model for the Earth. Algorithms are optimized for maximum accuracy and performance. A math coprocessor will be used if it is detected. If not, IEEE floating point emulation is performed. Objects in the BSC range in visual magnitude from -1.46 to 8.2.
Stars appear brighter according to their visual magnitude.
The effects of general precession and nutation are accounted for in determining star positions. The suborbital point data base contains the name of every country in the world, each of the U. S. states, the names of oceans, lakes, and other bodies of water, as well as other major geographic features. Micro Orbiter utilizes expanded memory if available. General Information Compute Doppler shift and antenna pointing angles. Track in both real and simulated time.
