Mobile SATCOM Service Provided by Inmarsat Government to South Orkney Islands Expedition


Inmarsat Government has successfully provided mobile communications support to the South Orkney Expedition.

This multidisciplinary expedition, supported by the research vessel RV Braveheart, took place on Signy Island from February 21 to March 6, 2020. The South Orkney Islands are located in the Southern Ocean, about 375 miles north-east of the Antarctic Peninsula.

This expedition was undertaken by the Perseverance DX Group, a nonprofit expedition organization that conducted record-setting, multi-mode high frequency (HF) communications using amateur radio frequencies, ranging from just above the Amplitude Modulated (AM) broadcast band to the edge of the very high frequency (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 their Broadband Global Area Network (BGAN) SATCOM services that enabled expedition members to partner with schools to supplement STEM classroom education of the Antarctic. Furthermore, the expedition relied on Inmarsat’s highly dependable Global Satellite Phone Service (GSPS) via the Inmarsat-4 constellation to stay connected in this remote region.

Dr. David Lloyd, South Orkney Expedition leader, said these internet activities would not have been possible without Inmarsat’s services and the expedition appreciates 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.”
