1. How many database do space software use? 2. Where do they keep their databases? 3. How to keep up-to-date databases for space software when we have obtained the SRS-on-DVD and getting space BR IFIC every 2 weeks?
	1. With regards to planned frequency satellite bands, what is the maximum number of satellites that can be deployed by an administration in an orbital slot? 2. Again, as regards to planned frequency satellite bands, is there any ITU procedures to be followed if an administration finds that an unauthorized satellite is operating in its orbital slot? 3. How can an administration obtain satellite monitoring services from regional satellite monitoring systems already put in placed by certain administrations? Is there any ITU procedures associated to the said systems?
	Dear Sir, The table com_el is not included in the database structure in the preface document as well as in the presentation. Why is not the relationship between tables also implemented in the access database? If I use the tools and relationship of access, I will only get a list of tables with the fiels and the primary/foreignkey in bold but not with the lines connecting the tables in the database. Thank you.
