  3. Responsibilities GSFC Data Systems Standards Management The general responsibilities of the GSFC Data Systems Standards Manager are to manage the implementation of the GSFC standards program; and to promote the identification, development, selection, and use of technical standards on GSFC programs and projects. This position reports to Madeline J. Butler, Associate Chief Engineer, Code 500 Applied Engineering and Technology Directorate; and Roger Clason, Code 453, Technology and Mission Upgrades Project. P1J Navigation Data Subpanel Responsibility for definition of recommendations for standards applicable to the exchange of navigation data. NTAG MEETING/P1J

  4. Accomplishments: Standards management • March 27-29, GSFC supported the Range Commanders Council (RCC) meeting at Yuma, AZ. • March 20, GSFC personnel met with John Kelly and Linda Kezer, to talk about the status of the CCSDS web site. A GSFC led working group will formulate recommendations to reengineer the site. • Still in-work, a resolution on the NASA policy on exporting software, applicable to the CCSDS proposal to establish an on-line software library. Ref. MC-S00-A09. • Providing weekly reports to Andy Dowen, JPL, SOMO Chief Engineer. • Present CCSDS/Standards activity report to the GSFC Standards Coordination Meeting and the Technology and Upgrades Project, monthly. • GSFC Data Systems Standards group meetings are conducted on a regular basis. NTAG MEETING/P1J

  5. Accomplishments: P1J Activities • Last P1J workshop October 17-20, Vilspa, Spain. (CCSDS Fall series). Completed a detailed review of the green book; subject: navigation definitions and conventions. Established topics for new red books, to define recommendations for orbit, tracking, attitude, proximity ops, environmental models and astrodynamic constants • Currently working on final review of P1J green book. To be submitted for acceptance following the May workshop. • Currently working on initial review of P1J white book. Subject: orbital data messages. Final version may be ready following the May workshop. • Planning support to P1J, TSG, and MC meetings, next May. NTAG MEETING/P1J

  6. P1J Future work • Development of new P1J CCSDS white books (red books) on recommendations for orbit, tracking, attitude, proximity ops, environmental models and astrodynamic constants. • IACG has increased the scope of Working Group 4 (Tracking, Commanding and Data Acquisition) to investigate the current and future status and proposed demand for deep space tracking facilities. P1J will contribute recommendations. • Next P1J workshop, Spring 2001, May 9-11, at ESA/ESOC. • Joint P1J/P1K meeting, May 22, at Pasadena, CA. Purpose: To define a suitable set of CCSDS on-board time recommendations. NTAG MEETING/P1J

  7. Issues • Limitation in manpower dedicated to NASA and CCSDS standards tasks • Limitation of travel funding NTAG MEETING/P1J
