The Interpretation Centre, located on the premises of Jantar Mantar, Jaipur, was developed by the Amber Development and Management Authority. 

The artefacts are displayed in two galleries, the audio-visual room and the Astrolabe Gallery. An audio-visual clip is played to introduce visitors to Jaipur's observatory, its yantras and their working principles. The centre also exhibits models of yantras such as the Kranti Vritta yantra, the Rama yantra, the Laghu Samrat yantra and the Nadivalaya yantra. The Astrolabe Gallery has astronomical instruments on display along with a telescope, logarithm tables and wax statues of Maharaja Sawai Jai Singh (1688–1743) having a discussion with Portuguese astronomers (Father Manuel de Figueredo and Pedro da Silva Letao) over astronomical literature and tables from Europe.

The astrolabe is an extremely versatile instrument, offering solutions to problems as diverse as telling the time during the day or at night, establishing the precise moment of a specific celestial event, constructing horoscopes, determining direction and measuring the height of buildings. At present, there are around 22 astrolabes in Jantar Mantar ranging from 110 mm to 500 mm in diameter. These astrolabes were constructed in Jaipur itself and are approximately 100–150 years old. 

The Jantar Mantar complex also has a museum shop and a food-and-drinks kiosk.
