4.1 Overview
Section 4. Obtaining SN Services
The information in this section describes the process for obtaining SN services, which is
termed the Networks Integration Process. The process is described in the Code 450.1
Networks Integration Process, 450-PG-1310.1.1. The objective of the Networks
Integration Process is to ensure that customer requirements are documented and that
services are provided to meet customer objectives at the lowest life cycle cost. This
process incorporates the following principles:
a. Establish contact between NIMO (Code 450.1) and potential customers as early
in the planning phase as possible to assure mission concepts are developed
with full information about Code 450 services.
b. Proactively assist customers in capturing requirements by progressively refining
these requirements as their concepts evolve.
c. Maintain flexibility in working with potential customers to analyze alternative
flight/ground system concepts, innovative approaches, and cost trades.
Code 450 is responsible for overall commitment of services and facilities for NASA and
non-NASA customers. The Networks Integration Managers (NIMs) ensure that all
requirements and commitments are integrated, and that RF, loading and coverage
analyses are performed to ensure services are feasible.
4.2 Authorities and Responsibilities
Authority and responsibility for managing the SN, including the Networks Integration
Process, is the responsibility of the Code 450 Division at GSFC.
The NIMO (Code 450.1) is responsible for coordinating and providing customer
services. The SN Project (Code 452) is responsible for the management and
operations of the TDRSS and the SN ground terminal. The Space Network Program
Plan also describes these efforts.
4.3 Procedures for Obtaining SN Services
Initially, the customer must contact the NIMO and, using the NIMO questionnaire
(450.1-FORM-0008), provide adequate information for RF engineering analyses,
loading analyses, and coverage analyses. Then SN loading studies and preliminary
analysis of the capability of the SN to provide services are completed. A determination
is then made as to whether the customer requires any modifications to the SN in order
to meet their requirements. Should modifications to the SN be required for customer
