WASHINGTON — The Pentagon’s House Growth Company desires to listen to from satellite tv for pc producers about their capabilities to assist the company’s plans to deploy a big community of spacecraft in low-Earth orbit.
SDA in a request for information issued April 10 asks firms that intend to compete for an upcoming contract to substantiate that they are going to have the ability to meet particular technical necessities. A key concern of SDA is to to ensure satellites from completely different distributors are interoperable.
The subsequent procurement of satellites by SDA is predicted later this 12 months. The company intends to purchase 150 satellites to be launched in late 2024. The plan is to award a number of contracts as SDA desires to create an open market the place distributors can compete for orders. The priority, nonetheless, is to be sure that satellites from completely different producers can speak to one another.
“SDA is looking for trade suggestions on its capability to assist a homogeneous constellation design,” stated the request for data.
SDA already has acquired 28 satellites for its Tranche zero constellation. The subsequent batch of 150 satellites might be Tranche 1.

A essential requirement for SDA satellites are optical crosslinks. Any future army community has to have the ability to cross large quantities of information from satellite tv for pc to satellite tv for pc, from area to the bottom and from area to plane in flight.
Satellites for Tranche 1 should have optical inter-satellite hyperlinks and the power to ascertain and keep no less than three optical hyperlinks concurrently, with an goal of 5 or extra.
