The Department of Defence has extended until 2020 its managed satellite services agreement with Optus.
The agreement covers the Defence payload on Optus' C1 satellite and follows a $19.5 million, four-year extension signed by the parties last year.
"Optus Satellite is especially proud of our ongoing partnership with the Department of Defence and we continue to strive to deliver the support, services and satellite communications requirements of the Department," said Paul Sheridan, vice-president of Optus Satellite.
"As an enduring component of the Australian Defence Force’s satellite communications capability, Optus C1 provides critical enabling service for training and operations in Australia and the region," said Commodore David Greaves, commander, defence strategic communications, in the Defence CIO Group.
"The Defence payload on Optus C1 provided the ADF with its first sovereign satellite communications capability; the extension of this important agreement to the satellite’s end of life reinforces this important relationship with Optus," Greaves said in a statement.
C1 was launched in June 2003 and has separate payloads for defence and Optus' commercial customers.
The initial C1 contract was signed by Defence in 1999, with both Defence and Optus having equal responsibility for the satellite.
The satellite provides Defence with communications in the X, Ka and UHF radio frequency bands.
The financial terms of the extension were not disclosed.
