OHB Sweden is a leading Swedish supplier of space systems. We develop, build, test and commission satellites and subsystems for space missions in, for example, communication, earth observation and space research for institutional and commercial customers within and outside Europe.Job Description: We are seeking a highly skilled RF ISL Specialist to join our dynamic team. The successful candidate will be responsible for the development and implementation of an onboard RF Inter-Satellite Link on small satellite platforms.Key Responsibilities:
  • Mission Requirements Collection - Gather and analyse potential mission requirements for using RF ISL in small satellite constellations in LEO for LEO-LEO and LEO-GEO communications.
  • Technical Specifications Definition - Define technical specifications for the RF ISL, including frequency bands, data rates, modulation schemes, and link budget.
  • Market Research - Conduct market research to identify available RF ISL hardware suitable for small satellite platforms. Focus on Technology Readiness Level (TRL), power demand, mass, pointing requirements, and available data rates.
  • System Architecture Development - Develop a system architecture document outlining the RF ISL components and their interactions. Include block diagrams, flowcharts, and descriptions of the overall system design, with a focus on the Telemetry and Telecommand (TM/TC) concept of operations in S-Band.
  • Component Design - Create design documents for each RF ISL component, including transceivers, antennas, amplifiers, and filters. Provide schematics, circuit diagrams, and technical specifications for each component.
  • Signal Processing Documentation - Document the signal processing algorithms and protocols used in the RF ISL as part of a Space-to-Space Interface Control Document (ICD). Include mathematical models, flowcharts, and descriptions of the signal processing techniques.
