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. The query gives the number of assigned frequencies in the range and gives the distribution of the frequencies. For geostationary satellites the result is presented in a tabular form: columns for longitude intervals , rows for frequency intervals. You can navigate further by selecting a certain longitude interval: the histogram of the result is plotted at the end of the page. For non-geostationary satellites no further navigation is needed, the histogram of the result is plotted at the end of the page.
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
For geostationary satellites only:
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 number of intervals for longitude i.e.: divide the band starting at lower limit of the range upto the upper limit of the range
For geostationary and non-geostationary satellites:
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
enter a value for number of intervals for frequency i.e.: divide the band starting at lower limit of the range upto the upper limit of the range
and click on Select button.
To restart your query click on Cancel button.
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?
You may click on the highlighted number of assigned frequencies to have the list of satellites using the frequencies. From the satellite list you may select a particular satellite to navigate further.
