Design & Analysis
Space Vector has over 40 years of experience in launch vehicle design and missile guidance and control (G&C).
Control System Analysis and Design
- Design - Given a vehicle system to control we can develop a model and feedback control system to optimize performance based on design goals.
- Implementation - Using the most modern tools we can implement the control electronics using hardware (CPLD, FPGM) or software (mP, DSP) implementations based on design goals.
- Independent Review - Space Vector can provide an independent review of an existing or proposed control system design including a comprehensive report identifying strengths and weaknesses of the design along with suggestions for improvement.

Space Vector produces a variety of custom avionics boxes for the launch vehicle industry. Some boxes are build-to-print to customer designs but most are designed-to-specification where Space Vector provides all the engineering design and documentation. We also perform all the necessary individual acceptance testing (IAT) on each unit and qualification testing required by the program.
Examples of custom avionics developed by Space Vector include:
- Power Distribution Units (PDU)
- Payload Sequencers and Switching Units
- Thrust Vector Control Junction Boxes and Controllers
- Vehicle Interface Units (AKA Missile Interface Units)
- Flight Termination System Relay Boxes
- Telemetry Signal Conditioners

Air Bearing Testing
The Space Vector air bearing facility is used to to test post boost attitude control systems in a space-like environment. This is a complete hardware-in-the-loop (HWIL) test running the flight software. TM data and laser pointer traces are used to verify system performance.

Special Test Equipment
Space Vector has developed a variety of ruggedized test consoles using proven data acquisition and analysis software together with data acquisition cards. The test consoles are centered around a COTS computer. Standard models are designed into a two to three stack 19-inch rack anti-vibration transit cases with an optional printer.
One of our key pieces of test equipment is the Telemetry Ground Station. This system can receive up to 5 S-Band PCM links (2200 to 2400 MHz) simultaneously. Each link has a 10 Mbit/sec data width and outputs can be configured as NRZL, NRZM, NRZS, and 422 data. The system uses dual processors operating at 450 MHz. Data is stored directly to an 18 GB hard drive for processing.
Space Vector owns two GPS constellation simulators: A Spirent GSS7700 and a dual output GSS8000. These simulators are used for testing our GPS tracking units under flight representative scenarios.
