Job description

We are building the next-generation Global Satellite Constellation for highly precise and secure Positioning, Navigation, and Timing (PNT) using Low Earth Orbit (LEO) satellites. We are seeking an RF & Communications Engineer to lead the development of Inter-Satellite Link (ISL). The role involves development of RF communication architectures, modem design, synchronization techniques, link performance analysis, etc. for space-based ISL.

Key Responsibilities

• Design, simulate and analyse RF ISL architectures under realistic orbital conditions for LEO satellites.
• Develop communication waveforms, modulation and coding schemes for satellite crosslinks.
• Perform RF link budget analysis for inter-satellite communication scenarios.
• Design synchronization, acquisition and tracking algorithms for ISL terminals.
• Work on Doppler compensation and carrier/frequency synchronization for high-dynamics LEO environments.
• Develop ranging and time-transfer techniques using RF crosslink signals.
• Support design improvements and component selection for hardware realisation of ISL.
• Evaluate spectrum allocation, interference and coexistence considerations for ISL operation.
• Support hardware integration, laboratory testing and realtime ground and space testing.
• Collaborate with other subsystems like navigation, timing, mission planning etc. during the entire ISL development.

Required Skills & Experience

• Master’s or PhD in Electronics and Communications Engineering, related field.
• Strong understanding of RF and digital communication systems including modulation, coding, synchronization and wireless link design.
• Experience with RF system analysis, link budget calculations and communication system simulations using tools.
• Knowledge of satellite communication systems, orbital dynamics effects on communication links and Doppler compensation techniques for high-dynamics environments.
• Familiarity with RF hardware concepts including transceivers, antennas, frequency synthesizers, signal generators and laboratory test equipment for communication system validation.
