Inmarsat supports HF, Amateur Radio communications for antarctic expedition

Radio Resource International report 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.�
