ABSTRACT If all ground product deliverables
such as spacecraft documentation, telemetry and
command databases, satellite simulators,
telemetry displays and Telemetry, Command and
Range Interface Units from the various satellite
manufacturers and suppliers were standardized in
hardware and software formats the integration of
these products into the satellite operators
Satellite Control System (SCS) would be greatly
reduced in scope, effort and time resulting in
significant cost savings.

• INTRODUCTION
• Introduction of better, faster, cheaper
  satellites
• Satellite delivery time reduced but complexity
  increased
• Leads to ground products integration on critical
  path
• Non-standard deliverables require unique
  integration solutions for every item, increased
  dependence on the supplier and a divergence away
  from a Fleet SCS Concept that would greatly
  reduce operational complexity and overhead

4

• Ground Products Standardization Aspects
• Spacecraft Technical Reference Material
• Deliver as Microsoft Word and VISIO (must be
  delivered in a non-secure format)
• Standard set and content consisting of
• Satellite System Subsystem Description
• Satellite Operations Manual
• Satellite Interface Control Document
• Satellite Constraints Manual
• Satellite Data Manual
• Ground Unit(s) Operations Manuals

5

• Ground Products Standardization Aspects
• Operating Procedures (Part of Operations Manual)
• Standard content for front matter and operational
  steps consisting of
• Purpose
• References
• Functional Overview
• Constraints
• Schedule, Support and Prerequisites
• Procedure Steps

6

• Ground Products Standardization Aspects
• Operating Procedures (Part of Operations Manual)
• Standard columnar format for procedure steps
• Step
• Action
• Command
• Telemetry Verification
• Note If the supplier uses a proprietary
  procedure code, the electronic versions of the
  run-time procedures must also be supplied soft
  (in native format, i.e. PIL, CCL, STOL, etc.) and
  in text format.

• Ground Products Standardization Aspects
• Database Standard Contents
• Standard content delivered as tab delimited flat
  files with strict version control and
  identification of version changes. A data
  dictionary must also be provided.
• Note All deliverables from the supplier that
  make use of the database information must all be
  in sync, i.e. if a database update is released
  it must also be accompanied by releases of the
  DSS load, procedures, etc.

8

• Ground Products Standardization Aspects
• Database Standard Contents (continued)
• Standard content delivered, as a minimum
• Telemetry IDs with short and long descriptions
• Command mnemonics with short and long
  descriptions
• TC definition parameters and format
• TC cross reference
• Conversion Polynomials

9

• Ground Products Standardization Aspects
• Database Standard Contents (continued)
• Red and Yellow Check Limits
• Memorized and derived telemetry list and
  definitions
• On-board Processor memory data
• Command verification information
• Command pacing and timing constraints
• Forbidden, critical or hazardous command list

10

• Ground Products Standardization Aspects
• Dynamic Satellite Simulator
• Delivered with multiple ITCRU interfaces
• Code written in high level language that is
  modifiable
• Multiple licenses
• Multiple deliveries tied to SCS development
• GUI front end interface with common look and feel
  from all suppliers

11

• Ground Products Standardization Aspects
• Dynamic Satellite Simulator- Standard
  Deliverables
• User Guide
• System Requirements Specification
• Algorithm Description Document
• OM Manual
• Interface Control Document
• Version Description Document

12

• Ground Products Standardization Aspects
• Training
• Standard content supplied hard and soft in Power
  Point or CBT format.
• Standard modules to consist of
• Satellite System and Subsystem Course
• Satellite Operations Course
• Satellite Interface Course
• Database Training Course
• Operational Constraints Review
• Anomaly Review of similar buses (based around
  Anomaly Reports that are in a standard format
  from all suppliers
• Instructor Manuals
• DSS, Encryptor and ITCRU Training

13

• Ground Products Standardization Aspects
• Acronyms
• A standard set of industry acronyms should be
  adopted by all satellite manufacturers and
  operators. This would minimize confusion between
  programs and would contribute to a shorter
  learning curve for new programs.

14

• Conclusions
• With a standard set of ground products
  deliverables from every satellite manufacturer
  the satellite operator could greatly reduce the
  integration time of a new satellite into their
  SCS and a Fleet Concept of operations could be
  instituted resulting in a minimization of
  overhead.
