The satellites of China's space program, largely managed by the PLA, exceeded 1,100 in orbit by August 2025, spanning weather, Earth observation, reconnaissance, and the Qianfan and Guowang megaconstellations.
Chinese telegraph code
The Chinese telegraph code, also called Chinese Commercial Code, assigns each common Chinese character a unique four-digit number. Created in Shanghai in 1871, it still appears on identity cards and visa forms.
Chinese Train Control System
The Chinese Train Control System (CTCS, 中国列车运行控制系统) is the automatic train protection standard on China's railways, with levels CTCS-0 to CTCS-4; levels 2 and 3 run its high-speed network.
Chinese treasure ship (宝船)
The Chinese treasure ship (宝船), also called baochuan, was the largest class of sailing vessel in Ming admiral Zheng He's fleet, which made seven expeditions from 1405 to 1433.
Chinese-CLIP
Chinese-CLIP (CN-CLIP) is an open-source family of Chinese-language image-text contrastive models in the style of OpenAI's CLIP, released by Alibaba's OFA-Sys team in 2022 and trained on roughly 200 million Chinese image-text pairs.
Ching Wan Tang
Ching Wan Tang (鄧青雲), born 1947 in Hong Kong, is a Chinese-American physical chemist who co-invented the practical OLED at Eastman Kodak with Steven Van Slyke.
Ching-Ping Wong

Chinook (checkers program)
Chinook is a checkers program developed at the University of Alberta from 1989, the first program to win a human world championship in a game of skill.
Chip Foose
Chip Foose is an American automotive designer and custom-car builder known for award-winning hot rods and for hosting Overhaulin'; he founded Foose Design in Huntington Beach, California.
Chip on board
Chip on board (COB) is a semiconductor assembly technique in which a bare integrated-circuit die is attached directly to a printed circuit board and connected by wire bonds.
Chip scale package
A chip scale package (CSP) is an integrated circuit package whose area is at most 1.2 times that of its die, surface-mountable directly on a board.
Chip seal
A chip seal, also called a seal coat or bituminous surface treatment, is a pavement preservation treatment that sprays asphalt binder and covers it with stone chips.
Chipboard (paperboard)
Chipboard is a low-cost paperboard made entirely from recycled paper waste, with a gray or brown uncoated surface, used for backing sheets, box partitions, and the inner plies of solid fiberboard.
Chipeta
Chipeta, formally Chipeta Processing, LLC, is a natural gas processing complex in Uintah County, Utah, on the Uintah and Ouray Indian Reservation, serving the Greater Natural Buttes field since 2007.
Chiplet
A chiplet is an independently manufactured die implementing a subsystem function, connected through a die-to-die interface and assembled with other dies in one package to improve yield.
Chiplet interconnect
A chiplet interconnect is a standardized die-to-die interface carrying data and cache-coherent traffic between separately manufactured silicon dies in one package, with UCIe, BoW, and Intel's AIB among the standards.
CHIPS and Science Act
The CHIPS and Science Act is a 2022 United States federal law funding domestic semiconductor manufacturing and research, with a total cost of about $280 billion.
ChipScope
ChipScope is a set of hardware debug tools from Xilinx, now maintained by AMD, that embeds logic analyzers inside an FPGA for real-time signal debugging.
Chipset
A chipset is the support silicon on a motherboard that manages input/output and communication between the processor and the rest of the system, once split into north bridge and south bridge chips.
Chiquita
Chiquita, also known as United Brands, is an international banana and pineapple brand sold in nearly 70 countries, tracing back to the United Fruit Company founded in 1899.
Chirag Oil and Gas Field
Chirag (Azerbaijani: Çıraq, meaning lantern) is an offshore oil and gas field about 100 km east of Baku, and part of the ACG block, where first oil was produced in November 1997.
Chiral topological mechanical metamaterials
Chiral topological mechanical metamaterials are engineered structures whose vibrations carry a handedness, supporting one-way edge states protected against backscattering by topology, analogous to the quantum Hall effect.
Chireix outphasing
Chireix outphasing is a power amplifier architecture, introduced by Henri Chireix in 1935, that splits an amplitude-modulated signal into two constant-envelope signals and recombines them efficiently.
Chirp
A chirp, also called a chirp signal, is a signal whose frequency sweeps continuously with time, used in radar pulse compression, FMCW automotive sensors, sonar, and LoRa communications.
Chirp (Google speech recognition)
Chirp is a family of automatic speech recognition models built by Google on its Universal Speech Model research, first released in May 2023 and available only through Google Cloud Speech-to-Text.
Chirp spread spectrum
Chirp spread spectrum (CSS) is a spread-spectrum modulation that sweeps a signal's frequency linearly up or down each symbol period, serving low-power long-range communication and time-of-flight ranging.
