Verify Guide Star Acquisition with Continuing FGSs
Abstract
After the shuttle deploys HST at the end of SM4 and at the beginning of SMOV4, it will be necessary to test and demonstrate HST's ability to acquire guide stars with the FGSs. This is a major pre-requisite for all observations by HST's SIs when precision pointing under guide star control is needed. This proposal will test the ability of each of the unreplaced FGSs to acquire a primary guide star while another FGS acquires a secondary guide star. After acquiring the guide star pair, HST will track these stars in finelock for approximately 10 minutes. When possible, use guide stars that have been successfully acquired and tracked in the past.
