      Combat Balloon To Improve Communications

      Space war, by 1st Lt. Elizabeth Kreft, Nellis NV (AFPN) Apr 26, 2006



      Warfighters who depend on ground communications for mission success will soon have improved
      technology, thanks to a system currently under examination here at the 2006 Joint Expeditionary
      Force Experiment.

      Combat Skysat uses balloons to take advantage of untapped airspace and improve line-of-site ground
      communications.

      "The former Air Force chief of staff, General (John P.) Jumper, wanted to explore the 'near space'
      realm," said Maj. Shawn Bratton, 111th Space Operations Squadron detachment commander. "Between
      where the satellites live and where the planes fly is a chunk of space where nothing is operating."

      Skysat is a radio repeater platform launched into near-space. It is attached to what can be compared
      to a weather balloon and can transmit information hundreds of miles farther than traditional radios.
      Cruising altitude is between 65,000 and 95,000 feet.

      "It simply changes the line of sight," Major Bratton said. "Special operators or any military member
      who either goes on convoy operations or works in an urban environment can benefit from it."

      Hilly terrain or thick walls in an urban environment can weaken radio transmissions, but if the
      signal is bounced off an aerial platform, it not only allows for clearer transmissions, it extends
      communication range.

      "The standard ground radio range is roughly 5 to 10 miles, but with Combat Skysat, warfighters can
      exchange information over more than 600 miles," Major Bratton said.

      In the past, satellites were used to provide the long-range relay ability for ground communiqué, but
      the lines were often clogged with high-priority information and were too slow for the fast-paced
      ground environment.

      "The satellite bandwidths are always heavily tasked, so Skysat provides a clear channel just for
      ground communication," Major Bratton said.

      The balloon takes about 20 minutes to launch, but can stay in the air an average of 12 hours per
      flight. It is remotely flown from the launch site through ballast and vent controls, much like those
      on a hot-air balloon.

      Depending on the hostility of the environment, the balloon either can be retrieved for future use or
      left behind.

      "It was created to be disposable," Major Bratton said. "Since it's basically just a bent pipe
      repeater the size of a coffeemaker the entire platform is relatively low-priced."

      With the cost of commercial geosynchronous satellites averaging more than $300 million a pop, the
      $6,000 skysat makes "low-priced" seem like a slight understatement.

      "Yes, it is definitely cost-effective," the major said.

      The cost may be low, but the capabilities Skysat provides to the warfighter are extremely valuable.

      "Communication is imperative to a special operations team," said 1st Lt. Rodger Jennrich, special
      tactics officer with Air Force Special Operations Command. Lieutenant Jennrich is one member of the
      JEFX Combat Skysat examination team, and he says what he's seen so far is an outstanding
      improvement.

      "Skysat will offer operators a variety to their communications package, which will allow us to get
      information back faster," Lieutenant Jennrich said.

      Additionally, ground operators won't have to carry two antennas to achieve long-range contact.
