General definition (in Hinduism)
Source: Sanskrit Vimarsah: The Dhruvabhrama-Yantra of PadmanābhaDhurvabhramayantra (धुर्वभ्रमयन्त्र):—The Dhurvabhrama-yantra is an oblong (āyata-caturasra) metal plate one side of which is designed as the Dhurvabhrama-yantra and the reverse side as a sine quadrant (Turya- or Turīya-yanta). The Dhurvabhrama-yantra proper is a kind of nocturnal, i.e. an instrument to be employed at night. Its construction is based on the apparent diurnal rotation of the stellar sphere around the celestial poles.
Among the various astronomical instruments described in these Sanskrit texts, the Dhruvabhtama-yantra is an interesting multi-purpose instrument. While it is generally difficult to say which instrument was invented by whom, we know fortunately that this instrument was invented by Padmanābha in the first quarter of the fifteenth century.
The Dhruvabhrama-yantra consists of an oblong (āyatacaturasra) plate with a narrow horizontal slit close to and parallel to one of the shorter sides, say at the top. Below the slit are drawn eight concentric circles, producing seven annuli or rings (koṣṭhakas). These annuli contain different scales and the legends pertaining thereto.
