Chassis Management Solutions
Crossfield Technology develops SOSA-aligned chassis management systems including IPMC, ChMC, and ChassisBerry development platforms. Our solutions implement Hardware Open System Technologies (HOST) standards with VITA 46.11 compliance. These systems enable real-time platform monitoring, fault detection, and system health management for embedded applications while maintaining full IPMI compatibility across Texas and Colorado operations.
Instrumentation Gateway
Our ultra-high-speed instrumentation gateways connect modular sensors to real-time processors via 100 Gbps fiber optic links. Designed for applications like physics-based simulation and environmental sensing, these systems support both high-bandwidth sensor arrays and ultra-low-power wireless deployments. The gateways facilitate seamless data transfer while maintaining SWaP constraints for defense and industrial applications.
Embedded Firmware Design
We develop embedded firmware across multiple platforms including FPGA SoCs, MCUs, and MPUs. Our engineering team implements real-time control systems using Embedded Linux, Altera Quartus Prime Pro, and Mentor ModelSim tools. Solutions span from simple sensor controllers to complex heterogeneous computing systems requiring precise timing and deterministic operation in remote environments.
RF Circuit Design
Using AWR Microwave Office software, our engineers create RF and microwave circuits for wireless communication and sensor applications. We specialize in high-frequency PCB layouts, integrated microwave assemblies, and antenna systems. The designs support both short-range high-speed communications and long-range environmental monitoring deployments across diverse operating conditions.
System Architecture Validation
We validate system designs using MATLAB/Simulink and other simulation tools to ensure architectural integrity before implementation. This process covers sensor network performance analysis, data throughput optimization, and thermal management simulations. Our validation process reduces development risks while accelerating the transition from concept to deployed systems for mission-critical applications.
