DYNAMICS.TXT

(Compiled by TC)

The file looks just like the PICTLIST.TXT file in that there is a space in the first column before the picture name. This file allows the user to specify different uncertainty values in different coordinate frames for different segments of a mission. Excerpts from such a file for DAWN at Vesta are:

FRAME='BOD_FRAME' APPROACH
ETLM=  1800, 1.D-6
VSIG= 0.200, 0.200, 0.200
PSIG= 0.0001, 0.0001, 0.0001
 F11A0001225
 F11A0001241
 ...
 F21A0003895

FRAME='dxR_FRAME' SURVEY
ETLM=  1800, 1.D-6
VSIG= 0.100, 0.100, 0.040
PSIG= 0.0001, 0.0001, 0.0001

There were a number of parameter changes as the mission progressed from Approach to Survey to HAMO to LAMO to HAMO2 to Departure, with transitions between phases requiring parameters of their own.
