The Board of Ordnance was a British government body. Established in the Tudor period, it had its headquarters in the Tower of London. Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence of the realm and its overseas possessions, and as the supplier of munitions and equipment to both the Army and the Navy'. The Board also maintained and directed the Artillery and Engineer corps, which it founded in the 18th century. By the 19th century, the Board of Ordnance was second in size only to HM Treasury among government departments. The Board lasted until 1855, at which point it was disbanded.

In 1904 the title was changed again to Third Sea Lord and Controller of the Navy. In 1965 the office of the Third Sea Lord was abolished. The post-holder is responsible for procurement and matériel in the British Royal Navy.

This includes the five great theodolites—great in name, great in size and great in accuracy—used in surveys of Britain and other parts of the world. Ramsden also provided the equipment used in the measurement of the many base lines of these surveys and also the zenith telescope used in latitude determinations.
Colonel Sir Charles Frederick Arden-Close, was a British geographer and surveyor. He was Director General of the Ordnance Survey from 1911 to 1922.

He was born Charles Frederick Close and changed his surname to Arden-Close in 1938 so as to comply with a bequest.

Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose, which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015 Ordnance Survey has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Business, Energy and Industrial Strategy. It was also a member of the Public Data Group.
