HALCA is commanded six days per week from the Kagoshima Space Center. The contact schedule for this week lists the times for each tracking pass.
Approximately 25% of HALCA's in-orbit time is used for engineering purposes: gain and system temperature measurements, pointing checks, and test observations.
Links to documents describing the interfaces and file formats for the VSOP mission are given in this page. Observers should not need to refer to this documentation as sufficient details should be given (in a much more user-friendly form) in the Information for Observers pages.
