Tree Display of Links |
AuraGateway manages links using a tree display such that the user can quickly
access any given link, and run a link analysis on that link. After an analysis
has been conducted, it is only necessary to click on that tree branch in order
to see the output report |

Batch Mode Calculation for Very Large Networks |
When networks get very large, and individual calculations become unwieldy, a
Batch Mode of operation is also available. With the click of a button, the link
analysis for every link in a network can be performed. |
|
Graphical Display |
For the larger networks, the user is encouraged to make use of the graphical
display options that map the network into KML files for presentation on Google
Earth or NASA World Wind. |
|
|
Rain Models |
Both the Crane and ITU (ITU-R P.618-9, P.837-5) Rain Models are included. |
|
Link Calculation Conditions |
AuraGateway calculates link budgets under the following
sets of conditions:
(a) Clear Sky
(b) Rain Impaired Uplink
(c) Rain Impaired Downlink
(d) Rain Impaired Uplink and Downlink |
|
|
Results |
Results can be viewed, printed, and exported using a comma separated variable
(CSV) file for import into a spreadsheet program. |
|
|
Link Margins & Impairments |
Impairments and Link Margins are specified and set by the user in a database
utility. |
|
Key Variables |
For a given set of earth stations and defined link margins & impairments, the
three key variables on a link are EIRP/Carrier, Transmitted Uplink
Power/Carrier, and Quality of the Received Carrier (Eb/No for Digital Carriers
and S/N for Analog). |
|
Analysis Starting Point |
AuraGateway allows the user to select which of these variables will be set for a
starting point. This typically will vary depending on the relative importance of
managing these variables. For example, a DoD client may require Quality
regardless of EIRP and Transmit Power. |
