Generation-3 Navigational Doppler Lidar device developed during earlier COBALT project.
To demonstrate maturation of the technologies…[testing includes]… an integrated hardware-in-the-loop simulation, aircraft testing, helicopter testing, and suborbital flight testing onboard a commercial, reusable rocket vehicle.
The Safe and Precise Landing – Integrated Capabilities Evolution project, or SPLICE, plans to develop, mature, demonstrate, and infuse precision landing and hazard avoidance (PL&HA) technologies for NASA and for potential commercial spaceflight missions.
PL&HA technology advancements are being pursued in the following areas:
– Navigation Doppler Lidar (NDL), which provides direct velocity and ranging measurements using Doppler-based techniques
– Hazard Detection Lidar (HDL), capable of generating a real-time, 3-D terrain map within a 50-meter radius of the landing target, at a sufficient range to allow for safe landing site determination
– Algorithms for performing guidance and navigation, including Terrain Relative Navigation (TRN) and Hazard Detection (HD)
– Advanced computing capabilities, via a high performance space computing-based platform with a path to spaceflight, capable of supporting processing-intensive algorithms for navigation and image processing
In order to demonstrate the maturation of the technologies, an integrated ground test and flight test capability will also be developed as part of the project. This includes an integrated hardware-in-the-loop (HWIL) simulation, aircraft testing, helicopter testing, and suborbital flight testing onboard a commercial, reusable rocket vehicle.
