ForceModel.F107Index Property

Top

Description

The F10.7 index value that is used by the Jacchia-Roberts and MSIS atmospheric density models to calculate the exospheric temperature at the Spacecraft's current epoch. These models use the F10.7 index value from 1 day previous to the Spacecraft's current epoch in calculating exospheric temperature, due to the time it takes for solar fluctuations to affect Earth's atmosphere. Therefore, the value reported by this property corresponds to the F10.7 index value 1 day previous to the Spacecraft's current epoch. Solar flux units (sfu) are 1x10-22 W/m^2/Hz. Note that you can not report F10.7 with files containing Tc/Kp data.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
