RECONFIGURABLE RADIOS
NASA reconfigurable radio communication to solve the problem of small data transfers over small distances.
In 2014, the Malaysia Air Flight 370 containing 239 passengers on board, went missing somewhere in depths of the Indian Ocean, and out of radar range. The search for the plane lasted almost three years, but after discovering they had been searching in the wrong places, and the search had cost over 160 million Australian dollars, it got called off on January 17th. (& Devlin, 2017) This was due to radio communication not being able to transfer over a broad enough distance. However, with the assistance of NASA, a solution to this problem is being discovered.
This is not the only time a plane has gone missing, and can be untrackable for many reasons. Depending on if the flight path is busy or not, it can either take moments, or 10-20 minutes to even notice the aircraft is missing. When a plane is flying over water, it must

‘“A reconfigurable radio lets engineers change how the radio works throughout the life of the mission, if requirements change or when the environment does,” says Thomas Kacura.’ (NASA, n.d.) Reconfigurable radios include various technologies and systems, such as cognitive radio systems. A cognitive radio is a system that can be programmed and constructed through the use of energy to use the optimum wireless channels from in the area. (Mitola, 2013) It is essentially a form of wireless communication, in which a transceiver, a device that can transmit and receive communications. The key aspects of these technologies are noticing free ranges nearby, using geolocation databases. Geolocation is judgement of the geographical location of an object, or in this case, a radar source. “Within seconds, you can keep track of all the aircraft in the world” says Jeff Anderson, from Harris
One of the disappearances involves Flight 19. “Five Avenger torpedo bombers lifted into the air from the Naval Air Station at Fort Lauderdale, Florida, at 2:10 in the afternoon” (“The Mystery”). The goal of the flight was to practice bomb runs and did not seem to be unusual. The pilots consisted of all students except for one commander whose name was Lt. Charles Taylor. However, the Charles Taylor was not familiar with the area around which they were flying. Taylor then became frustrated and confused which caused them to end up miles of course (“The Mystery”). Pilot experience when flying is important and could be the reason why a flight makes it to its destination or does not. Another disappearance involves the loss of NC16002. “NC16002 was a DC-3 passenger plane that vanished on the night of December 28, 1948, during a flight from San Juan, Puerto Rico, to Miami, Florida” (“The Mystery”). “Investigators focused on the fact that Huber wasn’t licensed to fly in the dark, using only instruments, and that the plane had taken off from the Bahamas before sunrise” (MacGregor 38). Pilot experience and training can be seen as the reason why these flights never made it to where they were supposed to go which is explanation as to why the planes
wireless communication got a lot of attention when a message was transmitted that allowed for
This report is on the Crossair flight 3597 crash which happens at Zurich airport on 24th November 2001. Analysis of Crossair flight 3597 will be covered, which includes details such as facts of Crossair flight 3597 crash, and the three contributing factors involved in the air accident. The three contributing factors are mainly Crossair, pilot error and communications with air traffic controllers.
The above mentioned airplane was a planned commercial passenger flight that took off from LaGuardia Airport, New York destined for Charlotte Douglas Airport in North Carolina on January 15, 2009. Six minutes after takeoff, the airplane was successfully abandoned in Hudson River after striking multiple birds during its initial climb out. The crew reported by radio two minutes after takeoff at an altitude of 3,200 feet, the Airbus experienced multiple bird strikes. The result of this multiple bird strikes, which occurred in northeast of George Washington Bridge was compressor stalls as well as loss of thrust in both engines. The Airbus was ditched in Hudson River after the aircrew discovered that they would not reach any airfield and turned southward. Fortunately, all the 155 passengers on board survived the accident though the Airbus was partly submerged and sinking slowly.
On February 24, 1989, United Airlines flight 811 was en route to Sydney, Australia from Honolulu, Hawaii. They later experienced decompression due to the cargo door failure in front aft during flight. Flight 811 made successful emergency landing at Honolulu with nine passengers missing out of 337 passenger aboard. The cargo door that was ejected on Flight 811 damaged engines 3 and 4, which led to crew to turn back to Honolulu.
The Malaysian airlines flight 370 took off at around 12:41 a.m. local time carrying 227 passengers and 12 crew members. MH 370 disappeared on March 8, 2014 during a flight from Kuala Lampur to Beijing. The last known position of MH370 was over the china sea and since its disappearance no one was able to track it. Then after the disappearance plenty of scientist were trying to get a signal from a black box to
American Airlines Flight 587 Aviation Accident Analysis Naif Alamoudi 4/25/2016 Abstract This paper explores multiple reports and articles based on the aviation mishap with American Airlines Flight 587. Reports and documents researched have been sourced from credible sources like the FAA and NTSB. This paper examines and applies concepts to fully understand what exactly happened to flight 587 and the technical aspects associated with it.
Unfortunately, they could not help. They were giving wrong information. After few minutes later they told their altitude was 9700 feet the plane hit the water and sank in the sea. List at least two causes Static ports were not able to transmit true information because it was covered with metallic tape Although, two pilots were not bad, they were not well trained.
Flight 370 was an international passenger flight that went missing on March 8, 2014. The flight was scheduled in route to Beijing, but it went missing throughout the second day after the plane took off from Kuala National Airport. At approximately 1:21 p.m., the communications and transponder signal were functioning no longer. There were no emergency calls at the time the plane had its last checkpoint. On March 24 at approximately 10p.m.Malaysia Standard Time, officials ceased the search as radio signals picked up debris found throughout a remote Indian Ocean. It is believed that all of the 239 passengers on the plane died (Preimesberger). From protests and outcries, to mourning and fallouts, it is still a distraught event that shocked the world.
Weather conditions- Sometimes the bad weather conditions become the huge problem for the aircrafts as they are not able to operate in bad conditions by which they get losses.
Flight 93, the flight that crashed near some fields in the outskirts of Pennsylvania. But what was it doing there? What caused the plane to miss its target and crash? These answers may soon be revealed when detectives can finally examine the planes black box, found just recently. Many answers however can be found through other pieces of info that have come up along the way during the investigations.
When I stepped into the large neatly organized white polished plane, I never though something would go wrong. I woke up and found myself on an extremely hot bright sunny desert island filled with shiny soft bright green palm trees containing rough bright yellow hard felt juicy apples. The simple strong plane I was in earlier shattered into little pieces of broken glass and metal when crashing onto the wet slimy coffee colored sand and burning with red orange colored flames. After my realization to this heart throbbing incident I began to run pressing my eight inch footsteps into the wet squishy slimy light brown sand looking in every direction with my wide open eyes filled with confusion in search of other survivors. After finding four other survivors we began moving our small petite weak legs fifty inches from the painful incident. Reaching our destination which was a tiny space filled with dark shade blocking the extreme heat coming from the bright blue sky, I felt my eyelids slowly moving down my light colored hazel eyes and found myself in a dream. I was awakened the next day from a grumbling noise coming from my empty stomach.
GPS is a navigational aid that is satellite based. It is made up of a network of 24 satellites in orbit around the world. The first satellite was launched in 1978 and the last was put into orbit in 1994. Every 10 years another satellite is put into orbit because each satellite is made to last that amount of time. The system began as a military application but in the 1980’s the government decided to make it available to everyone, anywhere, anytime. The system finds your position by measuring the time it takes to receive the signal back to the satellite. It then does that with other satellites to triangulate your position in relation to the earth. To calculate a position in 2D the system has to be locked on to at least three satellites, but for a 3D representation you need to be locked on to at least 4 satellites. Once the position is found the GPS can calculate much more info like speed, bearing, track, distance, etc… The GPS system is very accurate; Garmin (a leader in GPS technology) states that their newest receiver is accurate up to an average of 15 meters.
GPS is a system of satellites radio-transmitters that orbit the planet in great numbers; their purpose is to be able to pinpoint the exact location of an individual or any type of vessel that is equipped with a receiver transmitter within a very small radius. GPS navigation has had a great impact upon society in general as well and its commercial and military applications. Global Positioning is made available at no cost to anyone who has a GPS receiver unit anywhere on the planet. A GPS unit is able to give the user longitude/latitude information as well as, altitude, traveling speed, distance traveled, distance remaining and time in any type of weather conditions imaginable.
One of the latest advancements in wireless data. It is used in GSM (Global System for Mobile Communications) for transferring data in packets.
