LEOPOLD

LEOPOLD Is part of the program suite ESPIRE. It is a simple code whose function is the rapid determination of the principal parameters that characterise the low Earth orbit environment, for use with the EQUIPOT and SOLARC models. The input to the code is the orbital altitude.

Using empirical and theoretical relationships and in-built data bases, the code evaluates and outputs seventeen space environment parameters:

When the input form has been completed, pressing the button will start the calculation and bring up the "Results" page.

Parameters

The present version of LEOPOLD uses only one input parameter: the orbit altitude. A range of altitudes and the increment can be specified.

Results

LEOPOLD produces the files listed in the table below. A description of the format of the files can be brought up by clicking on their description in the table.

The report file spenvis_lep.html is a printable file containing the input parameters and summary tables. The spenvis_leo.txt file is used by the plotting routines to produce graphical output.
