We design, build, and field unique sensor packages for observation and data collection of high-speed events and space exploration.


At OKSI, we are leading experts in designing and fielding customer remote sensing packages for detection, tracking, and characterizing hypersonic platforms and re-entry vehicles. In partnership with DoD, NASA, SpaceX, and more, we develop high-altitude airborne sensors and support various programs, space-based techniques, and seeker technology for hypersonic interceptors and long-range strike vehicles.

We also extract calibrated thermal imaging over long distances of hypersonic vehicles, their bodies, and their wakes. For powered hypersonics, we can also identify and extract information from the engine in real time.

Our proprietary methodology for space-based detection of hypersonic vehicles can provide 3DOF location of the target and cue other OPIR sensors.


We have several sensors that operate at high altitudes on manned and unmanned platforms to monitor hypersonics, including SAMI (SCIFLI Airborne Multispectral Imager) designed to support observations of launch vehicles as well as hypersonic re-entry of space objects.


Our novel seeker solution for terminal vehicle guidance negates failures from optical windows reaching high temperatures at the stagnation point.

EO/IR Systems

With over 30 years’ experience in the development of unique EO/IR sensors for hyperspectral and multispectral imaging systems, our sensors cover the spectrum from the UV through LWIR, and into the Passive millimeter wave (PMMW). The applications cover nano-second spectroscopy, imaging, and imaging-spectroscopy, along with a wide range of configurations.




Our systems cover wavelength ranges from UVis, SWIR, up to MWIR and LWIR. Our sensors cover a wide range of configurations and performance characteristics.

4-D Imaging Spectrometer Sensors

Our 4DIS sensors intercept phenomenology measurements from ground tracker mounts, telescopes, and airborne platforms. 


We develop algorithms for anomaly detection, target detection, scene/terrain classification, spectral unmixing and subpixel target detection, along with airborne ATD/ATR using hyperspectral sensors. 


Using our 4DIS sensors to product up to 100k image cubes/second, we can study energetic events such as explosively formed penetrators (EFPs). The sensors provide 2D spatial, spectral, and temporal data.

Combustion & High Enthalpy Flow Diagnostics

Our expertise in reactive flow includes optical non-intrusive diagnostics for flow field and species characterization and mapping, in applications from rocket engine plumes, internal combustion, airbreathing combustion systems, and more.

Our techniques for real-time, in-chamber rocket engine diagnostics detect anomalies that can precede engine falure. With our rocket plume analysis, we can also determine engine, types of propellants, and performance characteristics.


We utilize the sensitivity and specificity of tunable laser absorption spectroscopy (TLAS) to produce sensors for combustion diagnostics and material testing. Our sensors provide high-speed, quantitative temperature and concentration measurements at arc jets, wind tunnels, shock tubes, and plasmatrons.


During static firing and live launches, our imaging spectrometers are used to characterize/measure rocket engine plumes. This is used in real-time for prognostic health management (PHM).


We are capable of taking spectral measurements on a nano-second scale, to study material composition based on spectral emissivity. We can also do ultrafast Schlieren imaging showing shockwave evolution during high energy events.


Whether in situ or remote, we have deep experience in analyzing rocket engine plumes to optimize performance and create predictive diagnostics. Our techniques also enable optimal use of expensive components in reusable rocket engines.


Modeling & Simulation

Modeling & Simulation

Modern airborne and space vehicles are moving towards highly complex system of systems (SoS) approaches that integrate advanced sensors and avionics with machine learning models.  Due to the scale, cost, and safety concerns of testing these systems in real-life, we use the latest digital engineering methods to design, test, validate, and deploy autonomous aircraft in photorealistic 3D environments. Our modeling includes the spectral/temporal/spatial characteristics of the observables, radiative transfer, computational fluid dynamics of the surrounding flowfield, and sensor model including optics and detector.

We have also created realistic simulations of targets in their environments using tools like SSGM, OSC, SPF, SPURC for space-based and airborne vehicles.


We model targets in their environments using validated tools and target models across the spectrum from the UV through LWIR.  Such modeling allows us to compute the spectral radiation at the sensor’s aperture.


We use relevant radiation transfer codes along with computational fluid dynamics to model and test sensors measurements. We can retrieve target parameters based on sensor measurements while simultaneously minimizing system uncertainties.


Using various scene generation AI.ML tools, we generate rich test-case environments for training Deep Learning (DL) algorithms for ATD/ATR.   The scene generation include realistic high-fidelity terrain and target models in various environments.

Space Exploration

Understanding the origins of our universe and beyond is at the forefront of many minds. Our experience in space-based mission planning and science gives us a unique perspective on space exploration. Our ConOps and astrophysics knowledge combined with our proprietary low SWaP sensors allow us to take targeted measurements to help answer many unknowns about planets and other celestial bodies.

Planetary Isotope Sensors

Isotope-ratio analysis is a powerful tool to elucidate planetary systems. Isotopic data can provide information on potential sources of water in the solar system, as well as evidence for life beyond Earth. We have developed a Capillary Absorption Spectrometer (CAS) that analyzes trace-gas and isotopes.


It has become clear that dust on celestial bodies without thick atmospheres will have sharp dust grains. Futhermore, the dust can be charged, causing static cling, which then erodes our Earth-based equipment and fabrics. With our extensive knowledge, we have novel techniques to mitigate these issues.


Our long history of ground-based, space-based, and planetary-based mission designs, our aid in mission operations helps ensure mission success from the scientific and engineering perspectives.
