Flight Dynamics Software

This page provides an overview of general software packages used to support flight dynamics studies and operations at the German Space Operations Center. Most applications have been developed within the Space Flight Dynamics Section and can be made available to external users on a license basis. Where applicable, further information is provided in the detailed description of the individual programs.



NAVLIB/NAVTOOLS

A package based Fortran90 library for flight dynamics applications. Also available in Ada83/95.

VENI/VIDI/VICI

A suite of three programs supporting general mission analysis. Features include ephemeris generation (VENI), visibility diagrams (VIDI) and plot generation (VICI).

ORI

The ORI program generates orbit related information in terms of ephemeris and event predictions. A precision numerical orbit propagator is used, which is applicable for all types of Earth orbiting satellites. Results are provided in both text and graphical form.

GeoControl

An integrated package supporting station keeping and colocation of geostationary satellites. Among others, the software is used at SES Luxembourg for the control of currently six ASTRA satellites.

LAUWIN/PATH/APMAN

A collection of three programns supporting the positioning of geostationary satellites. The programs cover the analysis of launch windows (LAUWIN), the design of injection strategies (PATH) and the optimization of apogee/perigee boost maneuvers (APMAN).

ODEM

ODEM is a general purpose orbit determination program for use with radiometric tracking data and GPS navigation data. It provides a precision force and measurement model.

ORAN

ORAN is an orbit determination error analysis software of Earth orbiting satellites. It is used to study the impact of statistical and systematic errors on the orbit determination and prediction accuracy based on the concept of consider covariances.

Geodyn II

Geodyn is a high precision orbit determination program developed by the Goddard Space Flight Center. It is employed for studies in GPS orbit determination.
