The OK-GLI, also known as Buran Analog BTS-02, was a Soviet atmospheric test vehicle of the orbital Buran spacecraft. It was constructed for the Buran programme in 1984, and was used for 25 test flights between 1985 and 1988 before being retired.

Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing behaviour and systems of aircraft or testing the atmospheric phase of launch vehicles and reusable spacecraft. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or atmospheric testing of launch vehicles and reusable spacecraft. This data is validated for accuracy and analyzed to further modify the vehicle design during development, or to validate the design of the vehicle.
