Inmarsat Supports HF, Amateur Radio Communications for Antarctic Expedition
Friday, April 10, 2020 | Comments

Inmarsat Government provided mobile communications support to the South Orkney Expedition. This multidisciplinary expedition, supported by the research vessel RV Braveheart, took place on Signy Island Feb. 21 – March 6. The South Orkney Islands are located in the Southern Ocean about 375 miles northeast of the Antarctic Peninsula.

This expedition was undertaken by the Perseverance DX Group, a nonprofit expedition organization that conducted record-setting, multimode high frequency (HF) communications using amateur radio frequencies, ranging from just above the AM broadcast band to the edge of the VHF band, under widely varying space weather (ionospheric and solar flux) conditions. The team also collected marine sediment samples for scientific research.

Additionally, middle and high school science teachers were provided information for use in their classrooms on a number of science, technology, engineering and mathematics (STEM) topics. The expedition team also tested satellite communications and new amateur radio technologies in this remote region of the world.

During the expedition, Inmarsat Government provided its Broadband Global Area Network (BGAN) satellite communications services to enable expedition members to partner with schools to supplement STEM classroom education of the Antarctic. The expedition also relied on Inmarsat’s Global Satellite Phone Service (GSPS) via the Inmarsat-4 constellation to stay connected in this remote region.

“These internet activities would not have been possible without Inmarsat’s services,” said David Lloyd, South Orkney expedition leader. “We appreciate Inmarsat Government’s cooperation, technical assistance and the equipment that included BGAN and satellite phone services. Conducting expeditions to remote parts of the world to do research and support student STEM education requires having communications equipment that can reliably provide voice and broadband data communications under extreme conditions.”
