MONITORING SKYNET

Hello and welcome back... Listening to Military frequencies is an exciting hobby but its hard to know if its actually active.
The Military often changes equipment more often than you and i change our underwear. So it was interesting when i read in the media that a new antenna based in South Australia (Adelaide) for Airbus Defence and Space’s Skynet secure military satellite communications is up and running (and active).

This new beast of an antenna (pic above) will connect with other country's including France, Germany, Norway, the UK and the USA.

From Airbus website = Skynet supports military satcom operations across the globe, especially in remote areas with little or no communication infrastructure and in mid-ocean, distanced from land and shipping lanes – making it ideal for naval and airborne platforms, as well as land operations.

Airbus Defence and Space completed the move of the Skynet 5A military communications satellite to 95° East over the Asia Pacific region in September 2015. The relocation was initiated to extend the Skynet constellation’s coverage and services from 178 West to 163 East, including the Indian Ocean and Western Pacific region.

SKYNET SPECS

Each Skynet 5 satellite is equipped with:
  • High power 160W TWTAs on all transponders, giving 56 dBW peak EIRP in each transmit spot beam and 41 dBW peak EIRP in each global beam per transponder.
  • 15 active transponders ranging in bandwidth from 20 MHz to 40 MHz
  • Up to 9 UHF channels
  • Multiple fully steerable downlink spot beams
  • On Board Active Receive Antenna (OBARA) capable of generating multiple shaped uplink beams
  • Flexible switching capability allowing connectivity between any uplink beam and at least two downlink beams
  • Nuclear hardening, anti-jamming countermeasures and laser protection

NOTICE = As with all military communications, if you do hear something, keep it to yourself.
With the ever changing world we live in, certain comms are not for public ears... so don't be stupid and enjoy military monitoring as a hobby before it becomes something we can no longer do.

Don't forget to shout me a coffee (see link top right corner)... Keeps this site happening :)
