Radio channel emulator. Radio channel emulators or radio channel simulators (also called fading simulators) are tools for air interface testing in wireless communication. In a test environment, radio channel emulators replace the real-world radio channel between a radio transmitter and a receiver by providing a faded representation of a transmitted signal to the receiver inputs. As technology moves forward to take advantage of more complex channel characteristics such as MIMO, the channel modeling needed to accurately emulate the radio environment becomes even more critical to a test setup. Radio channel emulators enable creation of mathematical models representing the physical radio signal transmission medium.

Typical use cases

MIMO Testing
The complex nature of a MIMO system creates unique measurement challenges in order to provide a test environment that fully simulates a real-world wireless channel. The radio channel emulator must have channel models that accurately simulate multiple antenna performance, including correlation between antenna elements.

Fairchild 100 Pilgrim. The Fairchild 100 Pilgrim is an American single-engined high-wing monoplane transport, and was one of a series of single-engine utility transports built by Fairchild Aircraft.

Design and development
The 100 was similar in design to the Fairchild C-8 and was an enlarged version of it.

The first flight of the aircraft (NC754Y) was October 22, 1930. Although only one aircraft was completed, a modified version also known as the Pilgrim 100-A was in production for American Airways, the first operator of the type in 1931. After a total of 16 aircraft, an additional batch of ten aircraft with a larger fin  were manufactured by the restructured American Aircraft & Engine Corporation that emerged in 1931 from the Fairchild Aircraft Co. The continuing series was built under the designations, Pilgrim 100-B and American/Fairchild Y1C-24.  The first six in the new series went to American Airways. The parent company later reinstated the Fairchild name.

Operational history
The sturdy Fairchild 100 series served as both an airliner and a bush plane. In 1932, the US Army Air Corps bought four Pilgrim Model 100-Bs designated the Y1C-24 and were initially assigned as light cargo transport and supply aircraft.

After a short time in service, the Y1C-24s were adapted for use as aeromedical evacuation aircraft, carrying up to four litter patients. The aircraft were assigned to pilot training and pursuit aircraft airfields for use as crash rescue aircraft. Exploiting the Y1C-24's ability to take off and land in a relatively short distance, the Y1C-24s remained in service into the late 1930s when they were replaced by newer air ambulance aircraft.

Variants

Pilgrim 100Prototype of the Pilgrim 100 family, powered by a  Pratt & Whitney R-1340 Wasp. designed by Virginius Clark, one built.

Pilgrim 100-A aka American Pilgrim, powered by a  Pratt & Whitney Hornet B, derived directly from the Fairchild 100. 16 were built, all of which were operated by American Airways.

Pilgrim 100-B Powered by a  Wright R-1820 Cyclone B, ten built, of which six for American Airways, and four to the US Army as the Fairchild Y1C-24.

Fairchild Y1C-24Military designation for the US Army Y1C-24, four built, powered by  Wright R-1820-1 Cyclone engines.

Pilgrim Y1C-24Alternative military designation for the US Army Y1C-24.

Surviving aircraft
Pilgrim 100-B N709Y is one of a few surviving aircraft from the early days of aviation in the history of Alaska. At the time of its listing on the National Register of Historic Places in 1986, it was the last Pilgrim that was still flightworthy.  It is now in the collection of the Alaska Aviation Museum.

Alexander Brebner. Sir Alexander Brebner CIE (19 August 1883 – 5 March 1979) was a British civil engineer who spent most of his career in India.

Brebner was born in Edinburgh, where he was educated at George Watson's College and the University of Edinburgh. He joined the Indian Public Works Department as an Assistant Engineer in 1906 and was promoted to Executive Engineer in 1912. He was appointed Under-Secretary in Bihar and Orissa in 1919 and Under-Secretary to the Government of India later the same year, a position he held until 1923 when he was promoted to Superintending Engineer. He served as Chief Engineer to the Government of India from 1931 until his retirement in 1938.

Returning to his native Scotland, Brebner served as Chief Divisional Food Officer for Scotland with the Ministry of Food from 1940 to 1942 and Licensing Officer for Scotland with the Ministry of Works from 1942 to 1954. He also served on the Council and Executive of the National Trust for Scotland until 1961 and on the Board of the Scottish Special Housing Association from 1954 to 1961, and was Acting Secretary of the Royal Scottish Academy from 1954 to 1955. From 1957 to 1964, he served on the ruling council of the influential Edinburgh conservationist body the Cockburn Association.

Brebner was appointed Companion of the Order of the Indian Empire (CIE) in the 1920 New Year Honours and was knighted on his retirement from India in 1938.

Clark Scamp. The Clark Scamp was a simple, bicycle-based moped similar in concept to the earlier 'winged wheel' or cycle motor, manufactured from March to November 1968 by Alec Clark, of A N Clark (Engineers) Limited, a business which normally manufactured telescopic extendable masts for antennas and small gearboxes for handtools in Binstead, Isle of Wight, England  

It combined a proprietary 1960s small-wheel cycle-type frame (obtained from the Co-operative Wholesale Society which sold the bicycle as the Commuter) with modifications to mount an innovative 50cc two-stroke engine close to (and outboard of) the rear wheel.

Manufacturing principal Alec Clark was an engineer with much experience of engine design including small-capacity two-strokes, having formerly worked for Trojan, a car manufacturer in Croydon, UK which in the 1960s offered a scooter and a light three-wheeler car and had undertaken development work for Leyland

With the exception of the Italian magneto and carburettor, all of the engine work was stated to be British-made.

Unfortunately, it was claimed by a Mr Coco that the Clark power unit was very similar to his own design which he had been trying to sell to Clarks for several months in 1967, before being informed that his design driving the rear wheel by friction caused unacceptable wear to the rear tyre and would not therefore be used.  

By the time the machine appeared on the market, it had a different drive mechanism but it was apparent that the power unit was closely related to the Coco design, so the designer sued for breach of confidence in that the drawings and prototype engine had been supplied to Clark for evaluation. 

The resulting case, Coco v AN Clark (Engineers) Limited, remains a fundamental statement of the principles of law in this area. An application for an interlocutory injunction to prevent any manufacture pending a trial outcome was refused at a hearing (the defendant undertaking instead to pay a royalty of five shillings per engine to be held in a deposit account and later apportioned after a trial ruling).

The trial never took place and the machine was discontinued after a production run estimated at 3,000 to 4,000. The company known as AN Clark (Engineers) Limited went into administration, and a new business - Clark Masts Limited - was formed to carry on manufacture of the core-business product.

Pseudomatrix. Pseudomatrix, as defined by Bill Dickinson in 1970, is the term for lithic fragments that have been deformed to become (part of or exclusively) a traditional sandstone matrix.  This is formed when a lithic-rich sandstone is compacted.  The compaction is usually more effective on the (typically) weaker lithic fragments in comparison to the stronger, coarser-grained framework grains.

Davison Army Airfield. Davison Army Airfield or Davison AAF  is a military use airport serving Fort Belvoir, in Fairfax County, Virginia, United States.

The airfield is located  southwest of Washington, D.C. It was named for noted World War II aviation engineer Brig. Gen. Donald Angus Davison.

The airfield provided support for Army One from 1957 to 1976 for presidents Dwight Eisenhower, John F. Kennedy, Lyndon Johnson, Richard Nixon, and Gerald Ford. Its role of support for the presidential helicopter ended in 1976 when responsibility for the helicopter was transferred entirely to the United States Marine Corps. The 12th Aviation Battalion (part of The Army Aviation Brigade, TAAB) now operates Davison AAF and the Pentagon helicopter pad. The battalion's 18 UH-60 Blackhawks including 4 VH-60 models ("Gold Tops") is responsible for priority regional transport for US Army and Pentagon senior leadership. 

The Civil Air Patrol National Capitol Wing uses a small tower for use during exercises and flights, and bases their four Cessna 172 and 182s there.

A helicopter operating a training flight from Davison was involved in the 2025 Potomac River mid-air collision.

Facilities 
Davison AAF has one runway designated 14/32 with an asphalt surface measuring 5,618 by 74 feet (1,712 by 23 m).
