Session Notes for rd0908 Prepared by J. Gipson and K. Baver, NVI, Inc./GSFC Schedule date: 2009-Sep-23 This is the second in a series of R&D sessions whose purpose is to improve scheduling of the Intensive sessions. We divide the 8 stations in this session into two subnets which are scheduled independently: 1.) The first subnet is the intensive network of Kokee-Wettzell. 2.) The second subnet is Fortleza, NyAlesund, Onsala, Tigo, Seshan, and Westford. The Kokee-Wettzell network is scheduled as a series of 22 independent intensives. A) The intensives that start on even hours: 2, 4, 6, etc are scheduled using the standard intensive sources and scheduling strategy. B) The intensives that start on odd hours: 1, 3, 5,... are scheduled using an enlarged source list. The 6 station network observes independently and serves as an independent external check on EOP. The GSFC analysis center will analyze the 22-pseudo intensive sessions with a view towards determining if one of the scheduling strategies is better in terms of things like: lower formal errors; better agreement with independent measures of UT1; robustness of the schedule. The schedule uses the standard R1 256 data-rate. =========================================================== ----- Parameter listing -------------------------------------- Experiment: RD0908 Description R&D-07 2009.
