Location: The Citadel Inn Ottawa101 Lyon St., Ottawa, Ont., ph. 613) 237-36001-800-567-3600Registration:$(Can) 100.00, cash exact amount would be appreciated(or $(US)80.00 also acceptable if preferred)The workshop, in addition to areviewof current approaches and possible improvements, willaddress the following issues:1. IGS Processing Center standard report requirements and format,2. Integration of results from Processing Centers into IGS (orbit) products,3. Initiate research towards future integration of regional cluster stations and distributedprocessing.AGENDA:Tuesday, October 12SESSION 1: IGS processing/reports/formats(Chaudi?re boardroom, convention level (1 level above the lobby))8:00 REGISTRATION (08:00-9:30)8:30 WELCOME/INTRODUCTIONJ.D.
