SpaceX has introduced a new website for its next-generation
@Starlink V3 satellites, along with new information about the satellite.
• 1 Tbps downlink capacity (~10× higher than Starlink V2).
• 160 Gbps uplink capacity (~22× higher than Starlink V2).
• 2,048 downlink beams + 2,048 uplink beams (vs. 192 downlink/144 uplink beams on V2).
• Upgraded phased array antennas enable the increased user capacity and beam count.
• New SpaceX-designed beamformer chips power the phased arrays.
• Modem chips handle ~64× more throughput per chip, allowing more efficient simultaneous service and real-time beam allocation based on demand.
• Each satellite includes 6 high-capacity 400 Gbps laser links, enabling a redundant petabit-scale laser mesh network for global routing.
• Each satellite also has 4 quad-band RF backhaul antennas operating across Ka, E, V, and W bands.
• RF backhaul capacity increases to 1.2 Tbps (>8× Starlink V2).
• Backhaul uplink supports 60 GHz of spectrum across frequencies and polarizations (4.3× more than V2).
• New solar arrays generate ~2× the power of the V2 satellite arrays.
• Solar arrays are manufactured using a continuous roll of solar blanket, cut into 19-meter sections, with 4 sections stitched together per array.
• Solar arrays are optimized to reduce atmospheric drag in low Earth orbit.
• A Starship launch carrying V3 satellites will deploy ~20× more network capacity than a Falcon 9 launch carrying V2 satellites.
• V3 technology will support future Starlink Mobile Gen 2 satellites, delivering terrestrial-like LTE speeds directly to unmodified smartphones.
