Orbits are displayed in three dimensions. The Earth, with continent outlines and coordinate grids (both optional), is shown. The orbit may be drawn as a connected line or individual points. The satellite ground track may also be drawn (with or without the orbit).

Precession of the orbit due to earth's rotation is included. This unfamiliar appearance is useful for radiation effects applications because the radiation belts and earth's magnetic field also rotate with the earth.

Simple mouse operations let you rotate and translate the image, and zoom in or out.

Menu operations let you display and print the image in B/W or color, copy the image to clipboard in vector (metafile) or raster (bitmap) form, individually select colors of image components, and adjust printed orbit line thickness.

Other Space Radiation files (geomagnetic and spacecraft shielding, energy and LET spectra, trapped proton and electron fluences, solar proton fluences, and dose-depth curves) are displayed as two dimensional plots. Energy and LET spectra may be output in integral, differential, or binned form.

Simple "rubber-band box" operation lets you zoom in on any area of the graph. New axis limits are selected exactly as your box indicates or are conveniently rounded. One mouse operation lets you choose optional features of the graph including logarithmic or linear axes, coordinate grids or tick marks, and solid or dashed lines.

Menu operations let you display and print the image in B/W or color, copy the image to clipboard in vector (metafile) or raster (bitmap) form, individually select colors of image components, adjust printed line thicknesses.

Notes:

The images displayed here are rasterized (bitmaps) and therefore have a fixed resolution. Instant Graphics also displays and prints images in vector format. Output appears at the resolution supported by your printer or other output device.

Environment Grid files cannot be displayed with Instant Graphics. The MapGVS module displays these as high-quality color contour plots.
