Overview

This implementation of the magnetic field models runs in combination with the orbit generator. SPENVIS verifies if a spacecraft trajectory has been generated prior to accessing the model page. If not, an error message is displayed with a link to the orbit generator. Please note that running the orbit generator will delete all existing output resulting from models that use the spacecraft trajectory.

The input parameters and options for the models are described below. When the input form has been completed, pressing the button will start the calculation and bring up the "Results" page.

Model parameters

SPENVIS Sets the IGRF/DGRF epoch equal to the start time of each mission segment. This epoch is used to select the appropriate model coefficients and to interpolate (or extrapolate) them as needed.

If an external field is selected, the model parameters (depending on the selected model) have to be entered.

Results

The magnetic field models produce the files listed in the table below. A description of the file formats can be brought up by clicking on their description in the table.

The report file spenvis_blp.html contains the input parameters and summary tables. The spenvis_blo.txt file contains magnetic field strength and vector components, L values and other parameters for each orbital point.
