- W4206476864 abstract "Distance and speed measurements from a single instrument is a powerful tool for navigation as well as situational awareness. Psionic has developed NASA’s NDL technology to the point it can become practical and cost effective for critical autonomous spacecraft operations. In this paper we discuss the advances made toward the commercialization of the NDL technology developed by NASA Langley. We will also show the results of testing in the laboratory and in flight that demonstrate some of the results of these upgrades. Overall, the work done decreases the cost, mass, and power while increasing performance and functionality. The system was conceived as part of a human lunar lander for precision landing at the lunar south pole. The high confidence velocity measurements allowed excellent inertial navigation from 5 km to the surface. With the improvements described here there now exists potential to use the same instrument for rendezvous and proximity operations as well as terrain relative navigation." @default.
