Australia’s flagship icebreaker has for the first time used drone
technology to navigate treacherous Antarctic waters, overcoming
significant technical hurdles, officials said Wednesday.
The
Aurora Australis is on an annual resupply voyage to Australia’s Casey
research station with images of sea-ice conditions from the quadcopper
drone helping navigation decisions.
The Australian Antarctic
Division said the unmanned aerial vehicle (UAV) was proving to be a
valuable addition to the current suite of sea-ice navigation tools,
which include satellite imagery and radar.
But it has not been plain sailing in the sub-zero conditions.
“The
electronics do not like snow, the batteries do not like the cold, and
the drone’s compass did not like the ship’s thousands of tonnes of
steel,” Australian UAV director James Rennie said.
“Because the
compass couldn’t calibrate on the ship and its need to work alongside
the unit’s GPS, there was potential for the UAV to behave unpredictably.
“We
found that by disabling the GPS and flying the drone in full manual
mode enabled the drone to operate successfully and deliver the required
footage.”
The drone carried out five missions during the nine-day
voyage to Casey, with a decision on its more permanent use for
navigation to be made after a review of the inaugural flights.
Australia
has four stations in the Antarctic wilderness and Aurora Australis has
already made a resupply run to its Davis outpost. It is also scheduled
to visit Mawson and Macquarie Island, delivering fuel, supplies and
expeditioners for the year ahead.
