Job Description:

Kratos Antenna Solutions is currently seeking an experienced Servo Motion Control Engineer to research, develop, plan and design electro-mechanical motion control systems for transportable/fixed earth station antennas. The engineer will have responsibility for the design, development, integration, and test of cutting-edge antenna pedestal drive systems used in satellite communication terminals utilized in ground transportable and fixed applications. The engineer is responsible for full-scope Design, Verification & Validation (IV&V) solutions for antenna products, including architecture trades, design, development, integration, deployment, and sustainment of antenna drive systems and associated integrated system verification solutions. The engineer will implement best practice standards regarding the planning, coordination, and implementation of antenna drive design and servo systems modeling with sound engineering process discipline and guidance. The effective candidate will have a good mechanical foundation and experience in dynamic real-time servo system design with specific knowledge in antenna pedestal or robotic control and system tuning. The position is located in the Plano, TX office and reports to the Principal Engineer.

  • Analyze, design, develop, support and troubleshoot control algorithms for Earth station satellite antenna servo systems
  • Will be responsible for analog, digital, S-domain and Z-domain controller design with appropriate analysis, modeling and simulation.
  • Responsibilities also include electrical, mechanical and software test and/or test support in the lab and in the field to verify system performance and troubleshoot problems. This includes test fixture design, assembly, test set-up and test data collection.
  • Responsibilities include characterization of servo motors, gearboxes, gear trains, and mechanical structures used for positioning satellite antennas.
  • Responsibilities also include requirements definition for individual servo components (electric motors - power, velocity, torque; gear trains - reduction ratios, backlash, friction, starting torque; feedback devices - resolution, accuracy, repeatability, etc).
  • Work with vendors to select off-the-shelf components or customized components to meet design criteria.
  • Responsible for keeping accurate engineering development records (test reports, analysis studies, schematics, block diagrams, theory of operations, white papers, etc).
  • Responsible for all documentation necessary to support production (test procedures, test records, bill of materials, interface control drawings, source control drawings, change requests, change notices, etc).
  • Responsible for generating documentation as necessary for customer support (conceptual presentations, PDR/CDR presentations, field instructions, troubleshooting procedures, field service bulletins). QUALIFICATIONS AND SKILLS:
    • Associates/Bachelor's degree in mechanical/electrical engineering or related field and 3-5 years engineering design work and precision motion control.
    • Excellent written and verbal experience is must
