Guidance, Navigation, and Control

Our employees and teammates have been a part of JPL and Lockheed Martin Mars Lander missions from Mars Pathfinder to Mars Insight.  The DSS team has created our own hardware in the loop testbed for our CLPS Lunar Lander. We can help your team with whatever GN&C challenge you may be facing, including Rendezvous Proximity Operations and Docking (RPOD).


We can rapidly transition your team from operational concepts to analyzable algorithms and testable flight software.


Our model libraries allow us to rapidly configure accurate and complete models of your mission and systems, including:

  • Dynamics (rigid and, if necessary flexible body)

  • Environments (gravity, atmosphere, solar pressure, magnetic field, etc.)

  • Sensors (star cameras, optical or radio navigation aids, horizon, sun, gyros, accelerometers, magnetometer, pressure, etc.)

  • Effectors (reaction wheels, thrusters of all types and sizes, torque rods, aero surfaces, etc.)

Simulation Model Development and Documentation

If the simulation models that you need do not exist, we can build them for you.

Object-Oriented Software Architecture/ Design

Our object oriented approach to simulation libraries and related flight software, ground test software, and flight command and telemetry software allows us to instantiate your mission system design and begin meaningful analysis and testing in days not months.


Contrary to traditional aerospace lore, you do not need a building full of VME racks of EGSE to have a hardware in-the-loop testbed.  We can help you make your spacecraft a safe test-like-you-fly testbed, and to clone cost-effective replicas of the core avionics to become HITL testbeds that can fit on a desktop.

Let us help you get more bang for your buck in test effectiveness.


You've got a bunch of data, but what does it all mean?  Do you have all the data you need to verify by test? Where does verification by test leave off and verification by analysis, inspection or demonstration pick up?  Do you have the analysis tools you need to complete those tasks?  Our expert analysts can help you get it right, starting with an Analysis Plan.
