Parakeet (communication system)

Last updated

Parakeet is an Australian Army mobile battlefield communication system. It was introduced into service in the mid-1990s through project JP65. Parakeet was considered (at the time) advanced military communications. This included secure voice and data trunking services. Project JP2072 has been recently raised to upgrade its sub-systems. It is operated by Royal Australian Corps of Signals (RASIGS) personnel.

Australian Army land warfare branch of Australias defence forces

The Australian Army is Australia's military land force. Formed in 1901 through the amalgamation of the Australian colonial forces following federation, it is part of the Australian Defence Force (ADF) along with the Royal Australian Navy and the Royal Australian Air Force. While the Chief of the Defence Force (CDF) commands the ADF, the Army is commanded by the Chief of Army (CA). The CA is therefore subordinate to the CDF, but is also directly responsible to the Minister for Defence. Although Australian soldiers have been involved in a number of minor and major conflicts throughout Australia's history, only in Second World War has Australian territory come under direct attack.

Military communications military operations and doctrine regarding communications

Military communications or military signals involve all aspects of communications, or conveyance of information, by armed forces. Military communications span from pre-history to the present. The earliest military communications were delivered by runners. Later, communications progressed to visual and audible signals, and then advanced into the electronic age. Examples from Jane's Military Communications include text, audio, facsimile, tactical ground-based communications, terrestrial microwave, tropospheric scatter, naval, satellite communications systems and equipment, surveillance and signal analysis, encryption and security and direction-finding and jamming.

Royal Australian Corps of Signals administrative corps of the Australian Army

The Royal Australian Corps of Signals (RASigs) is one of the 'arms' of the Australian Army. It is responsible for installing, maintaining and operating all types of telecommunications equipment and information systems. The motto of the Signals Corps is Certa Cito and is translated as 'Swift and Sure', signifying the aim of the signal service – that communication be carried out with maximum speed and certainty. Like their British counterparts, the Royal Australian Corps of Signals' flag and hat badge feature Mercury, the winged messenger of the gods, affectionately referred to by members of the corps as "Jimmy".

Kākāriki common name for three species of birds

The three species of kākāriki or New Zealand parakeets are the most common species of parakeets in the genus Cyanoramphus, family Psittacidae. The birds' Māori name, which is the most commonly used, means "small parrot". The etymology is: from kākā, parrot + riki, small. The word is also used to refer to the colour green because of the birds' predominantly green plumage. The patches of red on the birds' rumps are, according to legend, the blood of the demigod Tāwhaki. The three species on mainland New Zealand are the yellow-crowned parakeet, the red-crowned parakeet, or red-fronted parakeet, and the critically endangered Malherbe's parakeet or orange-fronted parakeet.

Members of the parrot genus Psittacula or Afro-Asian ring-necked parakeets as they are commonly known in aviculture originates found from Africa to South-East Asia. It is a widespread group, with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of Parrot which has the majority of its species in continental Asia. Of all the extant species only Psittacula calthropae, Psittacula caniceps and Psittacula echo do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, Psittacula krameri, is one of the most widely distributed of all parrots.

Parakeet auklet species of bird

The parakeet auklet is a small seabird of the North Pacific. Parakeet Auklets used to be placed on its own in the genus Cyclorrhynchus but recent morphological and genetic evidence suggest it should be placed in the genus Aethia, making them closely related to crested auklets and least auklets. It is associated with the boreal waters of Alaska, Kamchatka and Siberia. It breeds on the cliffs, slopes and boulder fields of offshore islands, generally moving south during the winter.

Echo parakeet Species of parrot endemic to Mauritius

The echo parakeet is a species of parrot endemic to the Mascarene Islands of Mauritius and formerly Réunion. It is the only living native parrot of the Mascarene Islands; all others have become extinct due to human activity. Two subspecies have been recognised, the extinct Réunion parakeet and the living echo parakeet, sometimes known as the Mauritius parakeet. The relationship between the two populations was historically unclear, but a 2015 DNA study determined them to be subspecies of the same species by comparing the DNA of echo parakeets with a single skin thought to be from a Réunion parakeet. As it was named first, the binomial name of the Réunion parakeet is used for the species; the Réunion subspecies thereby became P. eques eques, while the Mauritius subspecies became P. eques echo. Their closest relative was the extinct Newton's parakeet of Rodrigues, and the three are grouped among the subspecies of the rose-ringed parakeet of Asia and Africa.

This species that used to occupy the whole country is now confined to only a few areas on the mainland and some offshore islands.

<i>Sōryū</i>-class submarine JMSDF submarine

The Sōryū-class submarines (16SS) are diesel-electric attack submarines. The first boat in the class entered service with the Japan Maritime Self-Defense Force in 2009. The design is an evolution of the Oyashio-class submarine, from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders. The Sōryūs have the largest displacement of any submarine used by post-war Japan.

Talking bird

Talking birds are birds that can mimic the speech of humans. There is debate within the scientific community over whether some talking parrots also have some cognitive understanding of the language. Birds have varying degrees of talking ability: some, like the corvids, are able to mimic only a few words and phrases, while some budgerigars have been observed to have a vocabulary of almost 2,000 words. The hill myna, a common pet, is well known for its talking ability and its relative, the European starling, is also adept at mimicry. Wild cockatoos in Australia have been reported to have learned human speech by cultural transmission from ex-captive birds that have integrated into the flock.
