The following text and table will be placed on the ILRS web site. Use ”Toggle Mode” for monospace view in order to line up the columns. Regards, Mike ***** Historically, the SLR community has ordered its tracking priority list according to satellite orbital parameters and special project needs. Tracking priorities have been ordered as follows: 1. priorities decrease with: a. increasing orbital altitude; and b. increasing orbital inclination (at a given altitude). 2. priority of some satellites may then be increased to intensify support for: a. active missions (such as altimetry); b. special campaigns (such as IGEX 98); or c. post-launch intensive tracking phases; and 3. some slight reordering may be done to give higher priority missions with increased importance to the analysis community. Based on these criteria, the ILRS Governing Board has agreed to the satellite priorities as listed below. Stations may adjust priorities to accommodate local conditions such as system capabilities, weather, and special program interests.
