ISUAL, the scientific payload of ROCSAT-2 satellite began its operation since July 1, 2004. ISUAL consists of an intensified
imager, a 6-channel spectrometer and a dual-channel/16-anodes array photometer. The mission goals are to acquire spatial,
spectral and temporal informations of transient luminous events (TLEs) from an 891 km sun-sync polar orbit. A series of
post-launch on-orbit tests were performed to extract crucial instrumental parameters for data processing. We will report some
of the results.
To maximize the efficiency for global survey, the ground coverage of ISUAL at different spacecraft roll and yaw angles as
well as in different seasons was computed. By comparing the computed ground coverage and the global lightning distribution
maps obtained from satellites like TRMM, we can determine the best altitude of imaging in order to maximize the chance in
capturing TLEs. In this presentation, the salient informations for the groups that wish to perform future ground/space
coordinated observations of TLEs will also be provided.
*Works performed at National Cheng Kung University were supported in part by grants from NSPO (93-NSPO(B)-ISUAL-FA09-01) and
NSC (NSC93-2112-M-006-007, NSC93-2111-M-006-001) in Taiwan.
