The DSN Commitments Office is located at JPL in the Interplanetary Network Directorate (IND).
The Office personnel will assist persons designing new missions who are planning for support from the Deep Space Network (DSN).
Persons named above will provide potential users with information about DSN facilities, capabilities, and plans. Our personnel will review telecommunications link designs to ensure compatibility with the DSN.
Additionally, we will assist Development Flight Projects (DFPs) in completing a preliminary Deep Space Network Agreement (DSA), which is a high-level agreement of project support services requested from the DSN.
Our objective is to ensure that present and future DSN capabilities meet the need of new projects and that potential users understand constraints imposed by the DSN facilities.
No charge is made for support from the persons named above, and all contemplating the use of DSN capabilities are encouraged to contact the listed personnel.
IND's Deep Space Network (DSN) and the Advanced Multi-Mission Operations System (AMMOS) provide several documents and tools to assist persons preparing proposals for new missions.
Persons preparing proposals that require DSN and AMMOS services should carefully review the documents in this and the following section.
NASA has several Programs for which some information may be unique.
Proposers may download a desired document for the specific Announcement of Opportunity below by clicking on the document title.
2014 DISCOVERY PROPOSALS
2014 DRAFT AO
(File size: 1.4 MB ; July 2014)
NASA's Mission Operations and Communications Services - COMING SOON
This NASA Headquarters Portable Document Format (PDF) publication describes NASA's three communications networks including their capabilities, services, and costs. Costs and requirements contained therein are applicable to the New Frontiers Missions. Proposers should compute their costs for mission support based on the information in this document. Cost estimates for Advanced Multi-Mission Operations System (AMMOS) services can be obtained by contacting the persons named in Section 2.2. Also if interested in AMMOS tools & services, a copy of the AMMOS Catalog can be obtained by going to the “AMMOS Catalog” link provided below. Proposers seeking to use either NASA's Ground Network (GN) or Space Network (SN) should contact the person named in Section 2.3.
This Microsoft Excel spreadsheet calculates Aperture Fees for DSN stations in either Real-Year or user specified Fiscal-Year Dollars for Government, Government-Reimbursable, or Non-Government-Reimbursable missions. Computations are based upon a DSN Base Rate applicable to 2014. Thirty-five separate mission activities can be entered including passes for Multi-Spacecraft Per Antenna (MSPA), Delta-Differenced One-Way Range (DDOR), and Beacon Monitoring for which special cost adjustments are made. After downloading the form, carefully follow the instructions found by clicking the Instructions tab in the lower left-hand corner of the page.
DOCUMENTS APPLICABLE TO ALL PROPOSALS
This Portable Document Format (PDF) publication describes DSN services. In addition to DSN Earth station characteristics, this document also contains detailed descriptions of individual services contained in the Service Categories found in Table 1-1 of NASA's Mission Operations and Communications Services document. Performance characteristics of the services (quality, quantity, continuity, and latency) are discussed. It is highly recommended that persons planning to use DSN services consult this catalog.
Selecting this title links the viewer to a web site containing this Handbook. Frequently referred to as "810-5" this document provides technical design information about DSN stations and their telecommunications interfaces with flight projects. Proposers planning to utilize DSN stations should refer to the DSN parameter values contained in the several 810-5 modules when designing the spacecraft telecommunications systems. Copies are available at http://eis.jpl.nasa.gov/deepspace/dsndocs/810-005/.
This Link Design Control Table (DCT) Program is a set of Microsoft Excel files for a PC. It is configured to work with Windows 2000 and XP. Both spacecraft and ground system telecommunications system designers can easily use this versatile tool to do link design and analysis. The user should read the README file before downloading and running the tool. The DCT Program employs the recommended form adopted by the Consultative Committee for Space Data Systems (CCSDS) in Recommendations 401 (4.1.2) B-1 and 401 (4.1.3) B-1. The Excel program is consistent with other Recommendations adopted by the CCSDS. For technical assistance contact Anil Kantak at: (818) 354-3836. For a copy of the Recommendations please consult: Radio Frequency and Modulation Systems: Part 1: Earth Stations and Spacecraft (CCSDS 401.0-B).
DSN system designs are based upon internationally adopted standards. Use of standards promulgated by the organizations named below is required for interoperability with networks of other space agencies. Accordingly, users of DSN facilities are requested to comply with all standards applicable to their mission published by the organizations below.
The CCSDS Document Library contains recommendations published by CCSDS for spacecraft and Earth station data systems. Recommendations are documents providing detailed technical guidance to space agencies regarding the design of their space data handling systems. In addition to data formats, these Recommendations specify characteristics and capabilities of the physical transport layer. DSN users should comply with all relevant CCSDS Recommendations.
The International Telecommunications Union's (ITU's) Radio Regulations contain the internationally agreed rules for use of the radio frequency spectrum. Most missions supported by DSN Earth stations radiate signals across international boundaries. DSMS users should design their radio systems to fully comply with the provisions of this document.
The National Telecommunication and Information Administration's (NTIA's) Manual of Regulations & Procedures for Federal Radio Frequency Management governs radio frequency spectrum use in the United States by Government users. Because most missions supported by the DSN are operated by NASA, this document applies and DSMS users should be in full compliance. To obtain frequency authorization from the NTIA and to ensure protection from harmful interference, mission designers are encouraged to contact the Spectrum Management Office to begin the spectrum certification process as soon as possible, preferably before the mission’s MCR.
Space Frequency Coordination Group (SFCG) membership comprises some thirty civilian space agencies plus several observer organizations. Periodic meetings are held to discuss and adopt standards for use of the Space Science frequency bands. Recommendations are contained in the Handbook of the Space Frequency Coordination Group. Prospective DSN users should ensure that their spacecraft telecommunications systems comply with SFCG Recommendations.
DOCUMENTS APPLICABLE TO MISSION DESIGN
The documents listed below may prove useful to designers of new missions. These publications cover a broad range of subjects and readers should review the synopsis following each title to determine which ones may prove useful.
The point-of-contact for all Frequency Management items in the DSN is Farzin Manshadi, Farzin.Manshadi@jpl.nasa.gov, (818) 354-0068. Further information is available at http://www332/SpectrumGroup/
BANDWIDTH EFFICIENT MODULATION
The Space Frequency Coordination Group (SFCG) has reached agreement among its members that space science missions utilizing the Space Research service and operating in the 2 and 8 GHz frequency bands should employ bandwidth efficient modulation (see SFCG Handbook). The following Portable Document Format (PDF) reports summarize studies leading to the adoption of these agreements.
