Spacecraft programs need to make critical ADCS, propulsion, sensor, and power trade-offs early, before design lock, but doing those trades thoroughly while maintaining schedule momentum is difficult. When GNC and subsystem models don’t drive early design choices, teams risk discovering compromises late. And when hardware and software integration becomes the pacing item, timing, interface, and performance gaps surface only after full system integration is already underway.
FLEX and our space subsystems model library run comprehensive ADCS, propulsion, power, and sensor trades up front, keeping that exact architecture into SIL, HIL, and flight.
GuideTech’s customized GNC and flight software are developed and validated in closed-loop simulation early, so requirements and interfaces stabilize before design lock.
Our team integrates flight software, avionics, and sensors through computer and hardware-in-the-loop tests to verify timing, I/O, and performance long before full-stack bench testing.
We develop GNC and autonomy tailored to your specific vehicle and concept of operations to achieve your design’s maximum performance.
“GuideTech has been a key partner in translating novelty into real missions. They have supported mission planning for rapid and transorbital maneuvers, as well as development of flight software and operational design. This work has helped move Portal’s capabilities from hypothetical to demonstrable, creating a foundation for proof, operational use, future training, and mission rehearsal as these new maneuver profiles become part of real-world operations.”
