Workshop Overview Identify networks using a given frequency band Update the SRS database with IFIC data Do a Regulatory Date query

Identify networks using a given frequency band Frequency Query Identify networks using a given frequency band One or more frequency bands Orbital position range (optional) Notification reason (optional) Administration/Organization (optional) Beam Orientation (optional) Required Results: Which level of detail Sorting order

Frequency Query

Frequency Query

Frequency Query Exercise: 1) Find all notified networks having frequencies operating in either of the following frequency bands: Ku band downlink (12.5 - 12.75 GHz) Ku band uplink (12.75 - 13.25 GHz) Same query but display with a sample overlapping frequency. Same query but display all overlapping frequencies.

Export vs. Import SpaceQry has always had the philosophy of exporting data as opposed to importing data. Historically this is because of having the SRS database exclusively on a CD-ROM in the days when hard-disc space was limited. Because of this, the SRS was almost always used directly from the read-only CD-ROM.

Export vs. Import (2) Today, and in fact for the last several years, disc space is no longer an issue, so it is now relatively easy to maintain an up-to-date SRS database on your hard disc (or even on your iPod) which pretty well matches the BR's database.

Export vs. Import (3) Because of SpaceQry's historical "export" philosophy, the method for updating your local SRS is to export the new data from the IFIC database into the SRS database. To do this you need only…

Updating Your SRS 1) copy the SRS from the DVD onto your hard drive; 2) remove the read-only attribute of the SRS.mdb file; 3) every 2 weeks, download the new IFIC database from the web (or take it from the IFIC CD-ROM); 4) open the IFIC database with SpaceQry; 5) select the File:Export:Update the SRS menu option; 6) select your local SRS as the "target" database

Regulatory Date Query List the regulatory dates for frequency range(s) of a given satellite within its API / Coordination / Notification / Res49 cycle 1) Satellite Name 2) One or more frequency ranges (optional)

Regulatory Date Query

Regulatory Date Query Exercise 1) Perform a Regulatory Date Query (a.k.a.“Date-Link” query) for the following: Satellite network: THAICOM-A2B Frequency range: 10.950 – 11.200 GHz 2) Save results as an html document Hint!
