You will be able to watch the gun salute above from 12:00 BST.
Gun salutes are being fired across the UK in honour of Prince Philip, who died aged 99 on Friday morning.
The military recognition will take place in the capital, at the Tower of London and the Woolwich Barracks, as well as Hillsborough Castle in Belfast, Cardiff Castle, Edinburgh and several other locations including Gibraltar.
Gun salutes have been fired to mark significant national events, including the Queen’s Coronation and the deaths of Queen Victoria and Winston Churchill, since as early as at least the 18th century.
The public is being encouraged to observe the gun salutes, which will be broadcast online and on television, from home.
Prince Philip died peacefully in his sleep on Friday morning at Windsor Castle. He would have celebrated his 100th birthday in June.
The Duke of Edinburgh is expected to be given a ceremonial royal funeral rather than a state one and will not lie in state.
