Introduction

Before you start

Argus works best on larger screens. If you use a small screen and the view is too crammed, try reducing the zoom level of your browser with ctrl+”-“
Click on an orbit to display further details.

Important Concepts

Data hierarchy: Orbits are clustered in the following way: Network →\rightarrow Notified Orbits →\rightarrow Declared Orbits →\rightarrow Actual Orbits

Important Definitions

Actual Orbit: Orbit as per public OMM data.
Declared Orbit: Orbit for a spacecraft declared to ITU.
Tolerance Volume: The 30km Tolerance Volume is centered on the Declared Orbit line. Its radial extension depicts the 30km altitude tolerance for the spacecraft.

Control Elements Description

ElementDescription
a)Headup Display – Shows the position altitude, and, orientation of the camera in reference to the surface. Values can be set manually.
b)Side Panel – Select a data source and one or more networks.
c)Bottom Panel – Shows orbits of selected networks. Orbits can be searched and sorted.
d)Reset Camera View – Resets the camera position and pitch to the home position. Very helpful when you are lost.
e)Contacts – Opents the contacts widget with a collection of points of contacts for each system.
f)Legend – Offers further explanations about color scheme and tolerances

Interface Details

Bottom panel

ElementDescription
c1Show (all) notified orbits. Select which notified orbits should be displayed.
c2Notified orbits tab. Displays a list of notified orbits and their related actual orbits and declared orbits.
c3Filter: When selected, only notified orbits are shown where at least one actual satellite is not within tolerances.
c4Statistics tab. Displays altitude distribution for all satellites of selected networks.
c5Filter: When selected, all actual orbits will become visible. Press again to hde them again.
c6Select individual declared orbits, belonging to a notified orbit. When a declared orbit is selected, its tolerance volume is displayed as well.
c7Search fields: Narrow down the list by searching for matching values.
For example typing “>5” in the ‘Deployed Sats’ field will show all Notified orbits where more than 5 satellites have been deployed.
