(3) And then Arthur Ashe Stadium is named after Arthur Ashe who played professional men’s tennis from 1969 to 1980, becoming the first black player to win single’s titles at the US Open, the Australian Open and Wimbledon (three of the four tennis Grand Slams). She is renowned not only for her tennis prowess but also for her commitment to gender equality and social justice more broadly. (2) Billie Jean King National Tennis Center is named after the former top-ranked women, Billie Jean King, who played professional tennis from 1959 to 1990. At the time of drafting this article in mid July, no major withdraws had been announced for the 2021 US Open and 100% fan capacity is expected at the matches. The 2020 US Open was obviously held during the middle of the COVID-19 pandemic so it featured a reduced field with notable starts, including Rafael Nadal, Roger Federer and Ashleigh Barty, not in attendance.

These images have custom processing and color balancing applied by Apollo Mapping. Laykold courts have a variety of key differentiators according to the company website, with the major advantage being force reduction for the longevity of athletes’ bodies and joints.Ī 50-cm color image of the Billie Jean King National Tennis Center in Queens, New York collected on Jby Pléiades 1B and then a 1.5-m SPOT 6 image of the same stadium collected on July 6, 2020. In 2020, the United States Tennis Association (UTSA) announced a new 5-year agreement with Laykold to replace and maintain the court surfaces at Billie Jean National Tennis Center. Construction on Arthur Ashe was completed in 1997 by the engineering firm, WSP. The largest of the indoor arenas is Arthur Ashe Stadium with a capacity of 23,771. These capabilities can meet a wide variety of customer needs for a single test or a series of test and evaluation scenarios.In July we checked out the site of the opening ceremony for the 2020/2021 Tokyo Olympics, and for the August edition of the Pléiades 1 – SPOT 6/7 Stadium of the Month we head back to the United States with a look at the site of the next Men’s and Women’s tennis Grand Slam, Billie Jean King National Tennis Center in Queens, New York.Ībout the Stadium: Located on the northside of the Queens borough in New York City, Billie Jean National Tennis Center is actually a collection of multiple stadiums that surround 22 tennis courts as well as 12 outside courts. High-speed video and film cameras running up to 40,000+ frames per second are also available. Transducer data may be sampled at up to 1.25 MHz. Time-space-position information (TSPI) can be acquired at up to a 1-KHz rate, with accuracy within one foot. The facility uses photometrics, laser trackers, telemetry, and hardwire systems to gather data from a variety of instruments and transducers. The ACF has exceptional instrumentation capabilities. Test windows may vary between 10 seconds and one minute, depending on the vehicle velocity. Telemetry control and monitoring of the vehicle and onboard systems is available. Proven technology exists for vehicles and velocities in excess of 300 knots. Sandia engineers can design and build trolleys to meet specific customer needs, or customer-furnished hardware may be integrated for use as a cable car. A 200 x 225-foot net can provide a soft-catch method for items dropped from altitudes.Ī cable car or trolley can be rolled or rocket-propelled on a cable to flight velocity to serve as a test target (simulated aircraft for missile systems) or test platform (aircraft onboard systems). The ACF can also be configured to accommodate a wide variety of additional testing scenarios, including artillery firing and scoring, countermeasures and warning systems evaluation, and explosives testing. Target impact angles of 30 to 90 degrees can be achieved, and the angle of attack can be tightly controlled and measured. The ACF can conduct rocket-assisted impact tests, with impact speeds up to 1,200 feet per second. Can accommodate highly instrumented test articles.Used extensively in simulating B61 laydown environments.Can be elevated on back end to perform laydown-like impacts.I-Beam rail designed as “miniature” inverted sled track.Typically requires on-board data recorder in test article.High-speed imaging to provide diagnostics, impact parameters.Rocket sled is captured by catch box at top of track.Tow ropes are severed just above target so that the test unit impacts in free flight.Upon unit release from cable system, the rocket sled tows the test unit downward.Tow ropes pass through sheaves on the target, connecting the test unit to the rocket sled.Test unit suspended from aerial cable system.Utilizes rocket sled track and tow rope to pull test article towards target.
