DESCRIPTION = "The Small Forces File (SFF) provides to MSGR NAV Team's MIRAGE orbit determination software the following information: An estimate of the cumulative delta-V effect of thruster firing. an estimate of the cumulative spacecraft mass loss due to the use of propellant (fuel and oxidizer) while firing thrusters, an estimate cumulative on-times for each individual thruster. The file provides the accumulated value of these quantities since a specified start time which is normally set to the time of MESSENGER launch. The intent is for each file to present the running history of thruster firing events since the start of the mission. For generality, the capability to specify a start time (or T0) other than launch is provided." /* Data object definition descriptions. */ OBJECT = HEADER HEADER_TYPE = TEXT INTERCHANGE_FORMAT = ASCII BYTES = 2776 END_OBJECT = HEADER OBJECT = TABLE INTERCHANGE_FORMAT = ASCII ROW_BYTES = 346 ROWS = 647 COLUMNS = 31 ^STRUCTURE = "MESS_RS_SFF2.FMT" END_OBJECT = TABLE END
