Q

What does the CNPS database server do?

A

Maintains all satellite, terminal, frequency converter, waveform, modem, and filter statics used as the building blocks in defining the satellite communications services contained in
the CNPS scenarios which reside in the Master Planning Database (MPDB). The
Database Server also holds the active satellite configuration and all the associated
communications services contained in the “active on the satellite” scenario in the Operational Scenario Database (OSDB)

Q

What does the CNPS application server provide?

A

Application Server processes information and forwards requests between the CNPS Client and the Database Server and hosts various software functions such as the
Supportability Analysis engine for DSCS; a SA engine for WGS; SA engine provides the link budget calculations necessary for determining the supportability of a particular satellite configuration and its associated communications services.

*** Receives requests for information from the WSOMS workstation and sends the request to the Database Server. The Database Server sends the responses back to the Application Server. The Application Server processes the information and sends the response to the WSOMS workstation user. The Application Server speeds up communication within the network by caching requests. This allows the Application Server to store the most frequently used
requests for immediate processing

Q

What does the CNPS RemoteApp server provide?

A

Human Computer Interface (HCI) Client software that resides on the WSOMS
workstation. In V7.0, CNPS Clients also become virtual machines (VMs) residing on the
RemoteApp server and are accessible by RemoteApp shortcut and Remote Desktop
Protocol connection from any desktop.

** RemApp Server host all remote client VMs and will point all clients to the correct
Database and Application server, using its registry settings. (Note with Version 7,
There will only be one active Database and Application Server Running)

Q

What is OSDB?

A

When talking about the database server, it contains two databases. OSDB is one of them.

This contains information in the incorporation phase. The OSDB stores the operational scenario data that is considered “active on the satellite.” The OSDB allows other subsystems access to its data via the WSOMS database
management service for use in other operational activities. This allows other subsystems communicating with CPS to use information for reporting and other operational activities.

─ Satellites
─ Terminals
─ Frequency Converters
─ Waveforms
─ Modems
─ Filters
─ Jammers

Q

There are two categories of static data. They are…?

A
  1. Static Types - this is a blueprint for any form of static data. It does not represent specific physical hardware. Instead, it represents the performance characteristics of the static type. For example, WGS satellite, DSCS satellite, MD-1366 modem.
  2. Static Instances - this represent a physical piece of equipment. For example, the “Indian Ocean WGS satellite” is a static instance of a WGS satellite type.

Q

What is the difference between a plan, mission and service?

A

Plan - a folder containing one or more missions (the highest level of organization)

Mission - a subset of a plan containing one or more services

Services - subsets of missions (which are made up of associated terminals and the links that connect them)

22
Q

Even if there is a single Service to be created, it still requires a…?

A

associated mission and plan

23
Q

This is a crucial feature of CNPS planning. It tests a service to determine if it is supportable on the satellite.

A

Supportability Analysis (SA)

*** this examines each EPOCH to determine if it is supportable in conjunction with all other existing service and satellite configurations.

24
Q

A Service can be placed on the schedule after what occurred?

A

It passes the SA (supportability analysis)

25
Q

Services and Satellite Configuration changes progress through a set of steps:

A
  1. Plan Definition - the defining of day-to day plan, mission and service requirements and the defining of equipment characteristics (static data)
  2. Supportability Analysis - the model of satellite links or satellite configuration changes to determine supportability of new communication requirements. Used to analyze the effect satellite reconfiguration and static data changes have on existing communications, to evaluate all new Services against existing communications allocations and to confirm scheduled Services are supportable.
  3. Service Scheduling - the reservation of satellite resources for new communication requirements
  4. Service Implementation - Designation (part I) - is the process used to transition a service or satellite configuration change from scheduled to incorporation. Incorporation (part II) - the incorporation of the scheduled requirements into the operational scenario database (OSDB) resulting in the actual implementation of the modeled satellite links on the satellite.
26
Q

Changes to CNPS elements transition through system states as they progress through the workflow. To easily tell the status of that workflow, elements have been…?

A

color coded

27
Q

What is the order of operation for CNPS change transition?

A
  1. Create Plan/Mission/Service
  2. Definition
  3. Scheduled
  4. Designated
  5. Incorporated
  6. Complete
28
Q

Which state in the CNPS change transition is the following referring to?

  • The initial planning state where the operator defines the Plan, Mission and
    Service or satellite configuration change
  • Once the operator completes defining the elements of the Service or Satellite
    Configuration change, he or she runs SA
    ─ If the Service or Satellite Configuration change passes SA, it can be automatically
    transitioned to the scheduled state via the Auto Schedule feature
    ─ Any attempt to Schedule will run SA
A

Definition (cyan)

29
Q

Which state in the CNPS change transition is the following referring to?

  • An auto-scheduled Service transitions to ___ when it passes SA from Definition state
  • Once Service enters the Scheduled state, satellite resources are reserved
  • A Scheduled Service can be unscheduled and returned to the Definition state
A

Scheduled (yellow)

30
Q

Which state in the CNPS change transition is the following referring to?

  • A Scheduled Service/Satellite Configuration is transitioned to ___ after a Manager reviews the Service and verifies correctness
    ─ SA not run during Designation
    ─ Epochs may be Designated out of order
  • When the Manager Designates the Service/Satellite Configuration, it signifies the
    approval has been given for the Controller to Incorporate it
A

Designated (magenta)

31
Q

Which state in the CNPS change transition is the following referring to?

  • A Designated Service transitions to Incorporated after a Controller reviews the
    Service for any schedule conflicts
    ─ All epochs must be incorporated in chronological order
    ─ Conflicts are any epochs which must be incorporated prior to attempting incorporation
    of a new epoch
  • Once Incorporated, the Service is active in the OSDB, and the change can then
    be implemented by the various control subsystems
A

Incorporated (green)

32
Q

Which state in the CNPS change transition is the following referring to?

  • An Incorporated Service transitions to Completed when the Controller
    incorporates the end epoch
  • Once a Service enters the Completed state, it is no longer considered active on
    the satellite, and the Service no longer exists in the OSDB
  • The Controller can also transition a Service to this state prior to its end epoch by
    selecting the Terminate Now function
A

Complete (black)

A

DIMS dissemination procedure

*** Before conducting this, ensure that all WRMS subsystems associated with the IRON being disseminated are offline using the DIMS subsystem status report. You will want to make sure that both the operational state and collection state is OFF.
