International Application |
Frequency Plans are contained in a database table, allowing a user to conform to
any domestic and/or international frequency plan. The supporting rain models
allow operation of the program in all satellite frequency bands, including Ka
and V bands. |

Satellite Network Synthesis |
Provision exists for definition of satellites, transponders, earth stations, and
support facilities such as training centers, spares depots, etc. |
|
Network Comparisons |
A second network definition exists for the purpose of adjacent satelliite
interference studies. However, it can also be used to model an alternative
version of a desired network, allowing the user to easily switch between two
alternative network implementations in real time in order to compare specific
parameters with the two. |
|
Satellite Transponder Planning |
For transponder occupancy calculations, the use of time slots for TDMA and
orthogonal codes for CDMA carriers is supported in addition to FDMA for the
purposes of defining and analyzing channels. |
|
|
Link Analysis |
Link analysis supports clear sky and any combination of rain impairments. After
specification of the earth station parameters, three combinations of starting
point of the analysis/link performance objective are available. |
|
Adjacent Satellite Interference Analysis |
The approach implemented is a mirror network where the user can model a
potential interfering network at any level of detail, and with C/I calculations
between the networks based on the earth stations considered to be the most
likely source of interference. |
|
|
Earth Station Intermodulation Analysis |
The routine is structured to allow import of specific hardware parameters and
calculation of third order intermodulation conflicts in the uplink, downlink or
both. |
|
|
Work Breakdown Structure (WBS) |
The WBS is included for cost analysis and management of the network. |
|
Network Cost Analysis |
The cost analysis supports a variety of transponder purchase and leasing
arrangements from short term spot market rates to multi-year rates or simple
average rates per MHz of bandwidth. |
|
Comprehensive Reports |
A variety of reports and report formats are included to give the user maximum
flexibility in exporting and printing. For example, link analyses can be
exported as RTF documents, or in CSV spreadsheet formats or both. |
|
Graphical Displays |
The use of KML files allows the user to see the network layout using Google
Earth, NASA Worldwind and other GIS programs. |
|
|
Flexible I/O |
The program provides alternative methods of earth station inputs, ranging from a
template that requires little more than a set of coordinates and the ability to
edit, to detailed specification of each earth station in a CSV file that can
hold over 30,000 earth stations. |
|
Comprehensive Database Utilities |
Extensive use is made of database tables in order to provide the maximum
flexibility to the user. In addition to satellites, transponders, frequency
plans, carriers, earth stations, antennas, electronics components, etc. the user
can also specify and label link impairments and link margins that apply
primarily in their frequency band of interest. |
