In-flight connectivity (IFC) is one of the most demanding operational environments for satellite communications. Aircraft move fast, antennae are constrained, and passengers expect broadband performance that matches what they experience on the ground. Delivering that QoS over a satellite link requires a physical layer that performs at the ceiling of what the standard allows - consistently, reliably, across every phase of flight.

IFC systems must maintain high-throughput, low-latency connectivity through constant satellite handovers, variable link geometry, and the interference environment of a commercial aviation platform. Every fraction of a decibel of link efficiency matters. Every reduction in BLER translates directly into a better passenger experience and lower retransmission overhead.

AccelerComm's LDPC and Polar FEC IP, combined with the AccelerComm EVK for system-level validation, gives IFC system developers the physical layer performance and integration confidence to deliver broadband-grade connectivity from orbit. The same technology is already proven in orbit on more than 100 commercial satellites — including platforms used in demanding mobility applications.

KEY CHALLENGES

ACCELERCOMM SOLUTIONS

KEY CHALLENGE

  • Constant aircraft movement creates dynamic link conditions that degrade PHY performance in standard implementations

ACCELERCOMM SOLUTION

  • AccelerComm's FEC IP is optimised for operation across variable and degraded channel conditions, maintaining performance through the full geometry of a flight path

KEY CHALLENGE

  • Antenna and power constraints on aircraft platforms limit the link budget available for broadband services

ACCELERCOMM SOLUTION

  • Advanced LDPC decoding delivers 1 dB uplink sensitivity improvement, maximising the capacity achievable within the constraints of airborne antenna systems

KEY CHALLENGE

  • Passenger expectations for broadband-grade connectivity leave no tolerance for error-rate floors or service interruptions

ACCELERCOMM SOLUTION

  • Ultra-low BLER decoding eliminates error-rate floors and retransmission overhead, delivering consistent service quality throughout the flight

KEY CHALLENGE

  • Validating IFC system performance across the full range of operational conditions is complex and time-consuming

ACCELERCOMM SOLUTION

  • The AccelerComm EVK provides end-to-end system validation from Layer 1 through Layer 3, enabling confident performance assessment before deployment

KEY CHALLENGE

  • IFC programmes require physical layer IP that can be integrated cleanly into diverse platform and gateway architectures

ACCELERCOMM SOLUTION

  • AccelerComm's LDPC and Polar IP cores are FPGA- and ASIC-ready, with pre-validated interoperability and a clear migration path from evaluation to production
