Abstract

We investigate context-sensitive models for rover onboard data analysis. These “science maps” consider not only raw rover sensor data but also the sampling location. They improve onboard data understanding by revealing environmental trends and boundaries that can inform autonomous sampling and data return decisions. They also help identify novel features by highlighting anomalies that are unexpected in context of the local environment. In this work, tests with navigation imagery suggest that context-sensitive data analysis using a Hidden Markov Model offers performance benefits for novelty detection during rover traverse.
