Lynk Global

Last updated

Lynk Global is a company developing a satellite-to-mobile-phone satellite constellation that aims to provide a "cell tower in space" capability for global mobile phone service coverage, including in underserved rural areas without cellular coverage.

Lynk has requested a license from the US Federal Communications Commission to launch up to ten test satellites as early as 2022, with the goal to begin continuous global coverage in 2025 using a constellation of several thousand satellites. [1]

History

Lynk Global Inc. was founded in 2017 by Charles Miller, Margo Deckard, and Tyghe Speidel. [2] The business plan for Lynk came out of a multi-year effort to look for the killer app for small satellites, specifically satellites as small as cubesat-class nanosatellites, which led to the concept of connecting a satellite directly to a mobile phone. The idea had been thought to not be possible by some, but the Lynk concept and patents gave Lynk founders and investors confidence it was achievable. [2] Lynk raised US$20 million from investors during early years and expects to raise a US$100 million round later in 2021. [1]

In February 2020, Lynk "sent the world's first text message from a satellite in orbit to a standard mobile phone on the ground" in a test supported by both NASA and several mobile network operators. [3]

On 25 May 2021, Lynk filed with the US telecommunications regulator, the FCC, to license Lynk's satellites and multiple satellite launches, with the goal to enable global mobile connectivity from space-based assets. [3]

By May 2021, Lynk had launched four "cell-tower-in-space" test satellites into orbit. [4] The fifth one, Shannon, was launched on 29 June 2021 [5] and is a test sat of a new design suitable for mass production. Shannon is larger and operates at a higher power level and greater telecom capacity than the earlier test satellites. According to Lynk, the design is capable of being scaled up to provide greater communications throughput. [6]

On 25 July 2023, Lynk published the first public video demonstrating a satellite-to-phone voice-call, [7] though earlier in April of the same year, AST SpaceMobile claimed to have made the first space-based two-way telephone call with an unmodified smartphone. [8]

Technology

According to the company, Lynk satellite mobile technology is capable of connecting to standard [3] mobile phones from satellites in 500 km (310 mi)-altitude orbits. [2]

Lynk technology connects to mobile phones on the ground in a way similar to roaming networks, where the satellite mobile service will connect to another available cellular network when outside the range of its home network. To accomplish the regulatory side of this novel telecommunications method will require that Lynk work through the various geographically dispersed, and often country-specific, mobile network operators in any area of the world in which the service is to be available. [1]

Satellites launched

The first Lynk payloads to be tested in space have been flown attached to Cygnus spacecraft following their departure from the ISS. The first was tested on Cygnus NG-10 in February 2019, the second on Cygnus NG-11 in August 2019 and the third on Cygnus NG-12 in January 2020. [9] [10] Those have been followed by two free-flying test satellites, Lynk 04 ULTP and Lynk 06 Shannon, that have been launched on Falcon 9 Block 5 rockets in March 2020 and June 2021 respectively. [11] [12] The launch of operational satellites, named Lynk Towers, started in April 2022 with 3 satellites launched as of January 2023. [12]

A personal communications service (PCS) is set of communications capabilities that provide a combination of terminal mobility, personal mobility, and service profile management. This class of services comprises several types of wireless voice or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced cellular mobile or paging services. In addition, PCS can also be used to provide other wireless communications services, including services that allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other fixed locations. Described in more commercial terms, PCS is a generation of wireless cellular-phone technology, that combines a range of features and services surpassing those available in analogue- and first-generation (2G) digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.

Iridium Communications Inc. is a publicly traded American company headquartered in McLean, Virginia, United States. Iridium operates the Iridium satellite constellation, a system of 75 satellites: 66 are active satellites and the remaining nine function as in-orbit spares. Iridium Satellites are used for worldwide voice and data communication from handheld satellite phones, satellite messenger communication devices and integrated transceivers, as well as for two-way satellite messaging service from supported Android smartphones. The nearly polar orbit and communication between satellites via inter-satellite links provide global service availability.

<span class="mw-page-title-main">Satellite phone</span> Type of mobile phone

A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio link through satellites orbiting the Earth instead of terrestrial cell sites, as cellphones do. Therefore, they can work in most geographic locations on the Earth's surface, as long as open sky and the line-of-sight between the phone and the satellite are provided. Depending on the architecture of a particular system, coverage may include the entire Earth or only specific regions. Satellite phones provide similar functionality to terrestrial mobile telephones; voice calling, text messaging, and low-bandwidth Internet access are supported through most systems. The advantage of a satphone is that it can be used in such regions where local terrestrial communication infrastructures, such as landline and cellular networks, are not available.

Satellite Internet access or Satellite Broadband is Internet access provided through communication satellites. This technology enables users to access the Internet regardless of their geographical location. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using Ku band to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.
