Amazon Leo has now filed an application with the FCC to deploy 5,105 satellites for its proposed new direct-to-device mega-constellation. It plans to combine its Amazon Leo satellite network with Globalstar’s spectrum, satellites, and ground infrastructure. This will help it expand beyond emergency messaging to offer voice, data, and industrial IoT across geographies and service conditions.
Amazon Leo’s 5,105 satellites could expand direct-to-device connectivity
The application was filed by Kuiper Systems LLC (an Amazon subsidiary). It will use Globalstar’s wireless spectrum after Amazon completes its $11.57 billion acquisition of the company. The deal became official in April with a goal to expand its satellite network and boost direct-to-device services. It should finalize in 2027. Globalstar is quite popular already, mainly for supporting emergency satellite features on Apple devices.
The proposed satellites would operate in low Earth orbit at altitudes of 510km to 580km, with orbital inclinations of between about 56 and 84 degrees. The FCC filing includes orbital slots for more than 11,000 satellites. However, the company says the planned constellation would not exceed 5,105 satellites.
The company eyes Iridium’s spectrum for satellite connectivity
Amazon Leo also wants to use competitors’ Iridium’s exclusive frequencies in the 1618.725-1621.25MHz range outside of the United States. This, along with L-Band frequencies (1518-1525/1668-1675MHz). The FCC has now put out this filing for public review. However, the situation could become complicated as RocketLab is reportedly moving towards a deal to acquire Iridium for nearly $8 billion and is also interested in retaining these frequencies for itself.
However, in its listing, Amazon Leo says that its satellites will share the frequencies with other co-frequency and adjacent band users. It also ensures to take all required and practical steps to avoid harmful interference. The company also told the FCC that its D2D system will help expand mobile connectivity to more people and devices.Â
