Help on frequency distribution query

The scope of the query

This query allows you to make a search on the database by frequency range. In case of geostationary satellites the search is performed in a given longitude range.

Selection Options

list of all geostationary or non-geostationary satellites using frequencies in a given range

What to do?

select "Non-planned services" or "Planned services/SOF" from the radio buttons

select "GSO" (Geostationary) or "Non-GSO" (Non-Geostationary), in case of Non-planned services, from the radio buttons

enter a value for "Longitude (from)" i.e.: the lower limit of the longitude range

enter a value for "Longitude (to)" i.e.: the upper limit of the longitude range

enter a value for "Frequency (from) MHz" i.e.: the lower limit of the frequency range

enter a value for "Frequency (to) MHz" i.e.: the upper limit of the frequency range

if "Planned Services/SOF" radiobutton is selected check plan checkbox(es) and plan type radiobuttons

and click on Select button.

To restart your query click on Cancel button.

Remark

The values entered for the lower limit and the upper limit of the range are validated therefore

Make sure to enter numeric data.
Longitude (from) < Longitude (to).
Frequency (from) < Frequency (to).

For performance reasons please specify slots of the range where Frequency (to) - Frequency (from) does not exceed 500Mhz to 1GHz.

How to go further?

From the satellite list you may select a particular satellite to navigate further.
