NASA, FAA Demonstrate Wireless Communication with Aircraft

May 3, 2016 RELEASE 16-013
The next steps for AeroMACS will include end-to-end testing
For the first time ever, a team of engineers at NASA’s Glenn Research Center conveyed aviation data--including route options and weather information--to an airplane over a wireless communication system for aircraft on the ground.

The demonstration, which was conducted at Glenn’s Communications, Navigation and Surveillance (CNS) test bed in collaboration with the Federal Aviation Administration and Hitachi, LTD on Feb. 11, demonstrated two technologies that could change airport operations worldwide.

“This was the first time we provided this type of information to an airplane over a ground wireless network,” said Paul Nelson, Glenn’s project manager for Cyber-Security and Secure Communications, Navigation and Surveillance (CNS).

The team used an Aircraft Access to System Wide Information Management (SWIM), or AAtS, prototype technical solution to convey the aviation information to an FAA Bombardier Global 5000 test aircraft taxiing 60 to 70 miles per hour on the Cleveland Hopkins International Airport runway. They sent the information over a new wireless communication system called Aeronautical Mobile Airport Communications System, or AeroMACS.

The prototype AeroMACS hardware was developed by Hitachi. The system is based on WiMAX wireless communication standards, but uses different frequencies to enable connectivity on the ground. AAtS is an FAA technology demonstration and prototype initiative that enables solutions for connecting aircraft and flight crews to common-sourced aeronautical, weather and flight information. The AeroMACS demonstration enabled connectivity to allow updates to weather, airport status and flight and flow information prior to takeoff.

Until now, pilots have relied on voice communication with air traffic control or their airline operations center for this type of information because traditional wireless technologies don’t support high data throughputs. Together, AAtS and AeroMACS will improve situational awareness and reduce the potential for human error by giving pilots access to the information they need to make decisions. The trials consisted of three test cases designed to evaluate performance of both the AAtS and AeroMACS technologies. The trials demonstrated that AeroMACS can simultaneously transport multiple services seamlessly.
“It performed very well; it passed the test,” said Rafael Apaza, the AeroMACS technical lead. “We were able to send multiple applications to the aircraft at the same time and exchange surveillance and advisory flight information with fixed facilities without losing any data. This wireless communications capability will deliver great benefits to U.S. airport operations.”

In addition to improving safety, Nelson said the new wireless technology could allow airports to grow and change more affordably by replacing old underground systems.

“Airport communication systems use a lot of underground cables, which makes repairs and changes difficult,” he said. “Replacing and eliminating the underground infrastructure with wireless technology will reduce maintenance costs and downtime and allow airports to enhance capabilities more quickly.”

Glenn began investigating wireless communication technology for airports in 2004 and has worked with government and industry partners worldwide to develop AeroMACS and the wireless network standards. 

The next steps for AeroMACS will include end-to-end testing involving multiple airports and evaluation of security measures.

India is not complete without Kashmiriyat:PM Modi

PM announces eighty thousand crore rupee package for J and K

PM addresses public meeting at Srinagar

Srinagar: 7th November 2015: (PIB):
The Prime Minister, Shri Narendra Modi, today announced a development package of eighty thousand crore rupees for the State of Jammu and Kashmir. In his address at the Sher-e-Kashmir stadium in Srinagar, Shri Narendra Modi recalled former Prime Minister Shri Atal Bihari Vajpayee's message of Kashmiriyat, Jamhooriyat, Insaniyat.

"India is not complete without Kashmiriyat," the Prime Minister said, mentioning the Sufi tradition of India. 

He praised the people of the state for reposing their faith in Jamhooriyat (democracy) and said that the progress of Jammu and Kashmir had to be based on Insaniyat. 

The Prime Minister said his Government worked for "Sabka saath, sabka vikas," and therefore, it was essential for development to reach all parts of the country. He said the State of Jammu and Kashmir should return once again to the days when people from all parts of India saved money to visit the State. He said that besides tourism, attention was being given to sectors such as Pashmina, and Saffron. 

The Prime Minister narrated his experience of reconstruction following the Gujarat earthquake of 2001. He said that though the State of Jammu and Kashmir had suffered a lot due to floods last year, he saw the spirit (jazba) among the people, and was convinced that the State would soon overcome the difficulties. He recalled how he had rushed to the State soon after the floods and had spent Diwali last year in the State. He also recalled how his mother had given him Rs. 5000 last year for flood relief in Jammu and Kashmir. 

The Prime Minister said the atmosphere of gloom that pervaded India till recently has lifted over the last 17 months. He said India is now considered the fastest growing major economy in the world. 

The Prime Minister mentioned that the State from where young cricketer Pervez Rasool hails, should witness international cricket matches again. He said top Indian cricketers use bats made in the State. 

The Chief Minister of Jammu and Kashmir, Shri Mufti Mohammed Sayeed, Union Minister Shri Nitin Gadkari, and Union MoS Dr. Jitendra Singh were present on the occasion. (PIB)

The Japan Aerospace Exploration Agency (JAXA) has postponed the launch of its H-II Transport Vehicle (HTV)-5 to the International Space Station to 7:50 a.m. EDT on Wednesday, Aug. 19. NASA Television will carry live coverage of the event beginning at 7 a.m.

JAXA is delaying the launch from the Tanegashima Space Center in southern Japan due to an unfavorable weather forecast at the launch site for the next two days, which may delay the launch date further.

Loaded with more than 4.5 tons of supplies, including water, spare parts and experiment hardware for the six-person space station crew, the unpiloted cargo craft, named Kounotori, Japanese for “white stork,” will travel five days to reach the station.

Rendezvous and grapple of the HTV-5 now is scheduled for approximately 6:55 a.m. on Monday, Aug. 24. NASA TV coverage will begin at 5:15 a.m. Installation coverage will now begin at 9:15 a.m. for installation at approximately 9:45 a.m.
