************************************************************************ IERS Message No. 123 January 07, 2008 ************************************************************************ 37th COSPAR Scientific Assembly, Montreal, July 2008 Dear colleagues, I would like to draw your attention to the Call for Papers for the 37th COSPAR Scientific Assembly. The meeting will take place from 13 to 20 July, 2008, in Montreal, Canada. For more information, please visit "http://www.cospar-assembly.org/". The assembly will include sessions coordinated by the Panel on Satellite Dynamics (PSD) in cooperation with the COSPAR Sub-Commission B2 on International Coordination of Space Techniques for Geodesy and Geodynamics (CSTG). For more details, please click "Scientific Program Overview", then "PSD1". A description of the session topics is also included below. Please note that the deadline for submitting abstracts is February 17, 2008. For instructions, please click "Abstract submission". I wish you all the best for 2008. Sincerely, Pieter Visser (main scientific organizer) Pascal Willis (deputy organizer) Program abstract ---------------- The scope of the Panel on Satellite Dynamics is positioning of a wide range of objects on scales from giga- to nanometers. These objects include Earth orbiting satellites, such as geopotential missions (CHAMP, GRACE, GOCE), altimetry missions (Jason-1, ICESAT, CRYOSAT) and navigation satellites (GPS, GLONASS, GALILEO, including GIOVE-A and B, Beidou). In addition, planetary research is rapidly expanding leading to more and more (plans for) satellite missions (MGS, MRO, SELENE, Pluto Express). Moreover, formations of satellites are being proposed for Earth observation (Tandem-X/TerraSar-X) and fundamental science (LISA, Darwin, XEUS) that pose very high demands on (relative) positioning and orbit and attitude maintenance systems (such as micro-propulsion). Satellite orbit determination requires the availability of tracking systems (laser, DORIS, GPS, VLBI, Deep Space Network), and in conjunction accurate solutions for ground station positions expressed in well established reference frames, and detailed force and satellite models, such as gravity, drag and/or solar pressure. Contributions are solicited covering this broad area of positioning. ************************************************************************ IERS Messages are edited and distributed by the IERS Central Bureau.
