SL Modem/BBU
Hardware Specification
The satTRAC SL Modem/BBU provides telemetry, ranging, and commanding on a next-gen software radio platform
consisting of a high-availability commercial off-the-shelf server, a high-performance signal converter, and one or more
software applications. The tables below summarize the hardware specifications for the SL platform. Please refer to the
satTRAC top-level data sheet for an overview of the innovative capabilities of satTRAC. Refer to each individual software
application data sheet for a summary of the waveform performance specifications.
