SpaceX Wants to Increase Starship’s Power
SpaceX asked the FCC for permission to increase radio signal strength for Starship’s orbital return tests. Here is the new connection infrastructure planned for critical flight phases.
SpaceX applied to the US Federal Liaison Commission (FCC) to strengthen the connection systems of the spacecraft that will return from orbit within the scope of the Starship Orbital Return Demo mission. The company aims to increase the radio signal strength in the tests to be carried out at Starbase facilities by requesting an intermittent operating permit (STA), which is planned to be valid between July 29 and December 28, 2026.
This application, made to ensure that the critical information traffic and telemetry exchange during Starship’s return from orbit to Earth continues uninterrupted, covers the frequencies of 2056 MHz and 2062 MHz. This measure is of great importance to maintain the stability of the control mechanisms during high-dynamic flight phases where the vehicle interacts with the atmosphere.
- SpaceX requested permission from the FCC to increase signal strength for use in Starship’s orbital return tests.
- The requested frequency range covers the 2056 MHz and 2062 MHz bands, which are critical for the flight control of the vehicle and the transfer of telemetry data.
- Operations are planned to be conducted at Starbase facilities in Texas between July 29 and December 28, 2026.
- It is aimed to achieve 100 Watt transmission power and approximately 1 kW ERP costs in communication systems.
Communication Infrastructure is Strengthened
Starship missions to be carried out in the future require the vehicle to leave orbit safely and successfully complete the atmospheric entry phase. In this process, maintaining the relationship between Starship and ground stations is considered the key to flight success.
The technical documents submitted by SpaceX to the FCC reveal that M2 Antenna Systems FGFD-1-SC-2-N antenna systems and specially designed radio modules will be used. These hardware are optimized to ensure lossless transmission of information even in severe conditions at high altitude.
High-power radio signals play a vital role in minimizing data interruptions that may occur during Starship’s return from orbit.
Technical Needs Are Determined
The technical parameters detailed in the application indicate that radio modules with a transmission power of 100 Watts will be used. This value is converted into an equivalent broadcast power (ERP) of approximately 1 kW, ensuring that the signal remains accessible even in heavy layers of the atmosphere. In particular, the broadcast parameters of the 4M05G1D type provide a critical capacity for the tracking beam, which will be used both in transmitting information to the control center and in real-time tracking of the vehicle.
This infrastructure enables the vehicle to always remain in contact with the ground equipment, even in rapidly changing orbital conditions.
Process Pending Official Approval
This temporary permit application, assessed by the FCC, is seen as a module of technical progress in SpaceX’s space transportation program. Experts note that such a power increase has become a standard procedure in managing the flight dynamics of reusable superheavy systems such as Starship. The data provided by the company confirms that the engineering preparations necessary to keep communication channels open even during the most risky moments of the flight have been completed.
