5. April 25, 2001NTAG MEETING/P1J5 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.

6. April 25, 2001NTAG MEETING/P1J6 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.
