Radiation Environment for a Sun Synchronous Orbit

This page contains the SPENVIS information for the radiation environment of a Sun synchronous orbit lauched to an altitude of 500km.

The first figure shows the trapped proton flux for the orbit with a report file here:

The second figure shows the trapped electron flux for the orbit with data contained in the report file linked above:

The third figure shows the total dosage for a centre of Aluminium spheres model over a one year mission duration. The dosage is a function of shield thickness, and it's data is here:

Figure 3: Total dosage for a one year duration mission, 500km Sun synchronous orbit with a centre of Al spheres model

The final graph shows the total dosage for the same mssion parameters, but using a semi infinite Aluminium slab model. It's report file is here:
