Starlink Launches More Satellites Amid IPO Buzz
SpaceX launched 25 new Starlink satellites from Vandenberg Space Force Base on March 8, bolstering its West Coast operations. The aggressive expansion is fueling speculation of a potential SpaceX IPO this year, with analysts projecting a $1.75 trillion valuation, as the company also plans a $650 million investment in its Starbase facility.
The consumer-facing "Dishy" terminal is an integrated phased-array antenna, a technology once confined to multi-million dollar military systems like the F-22's AESA radar. SpaceX commoditized this by using custom silicon, reducing the number of beamformer chips from ~80 to ~6 between early generations, and employing hybrid PCB materials to cut costs to an estimated $400 per unit. This allows electronic beam steering in microseconds to track satellites moving at 7 km/s, a feat impossible for mechanically-steered dishes. Each satellite itself is a node in a space-based optical mesh network. They employ three optical inter-satellite links (ISLs), or space lasers, operating at near-infrared wavelengths (~1550 nm) to route data between satellites at up to 200 Gbps, bypassing ground stations entirely for transoceanic or polar communication. This laser communication technology is now being offered to third-party satellite operators. Onboard processing and control systems rely heavily on custom ASICs and FPGAs, a focus area for SpaceX's silicon engineering teams. These chips manage everything from the five Ku-band phased array antennas and three dual-band antennas to the ion propulsion thrusters, which were the first to use argon in space. Custom-built star trackers provide precise orientation data for agile attitude control via four reaction wheels. To achieve its rapid deployment cadence, SpaceX has vertically integrated its manufacturing, bringing PCB and electronics assembly in-house. The Redmond, Washington facility operates more like a consumer electronics line than a traditional aerospace factory, using high-speed pick-and-place machines and automated optical inspection. This allows the company to produce six satellites per day. The $650 million investment in Starbase supports the development of a "Giga Bay" designed to house 24 Starship rockets. The expansion is heavily reliant on robotics and automation for welding, assembly, and quality control, driving a need for mechanical and electrical engineers. The recent acquisition of AI firm xAI is expected to further integrate artificial intelligence into this automated production, shifting from anomaly detection to predictive and prescriptive process control.
