Introducing a globally consistent orbital‐based localization system

Abstract: In spite of the good performance of space exploratory missions, open issues still await to be solved. In autonomous or composite semi‐autonomous exploration of planetary land surfaces, rover localization is such an issue. The rovers of these missions (e.g., the MER and MSL) navigate relatively to their landing spot, ignoring their exact position on the coordinate system defined for the celestial body they explore. However, future advanced missions, like the Mars Sample Return, will require the localization of … Show more

“…Apart from reducing the dependency on communication passes, it also virtually eliminates the limit on traversed distance per Sol, except for the obvious energetic constraints. The main issues with the different absolute localization techniques developed so far (see [18], [19], [20]) is either a lack of reliability, low precision or the need for big amounts of data (or a combination of these). The approach presented here to estimate global pose corrections does not require big amounts of data, it actually (re)uses the local map generated by SLAM.…”

“…However, LiDARs are hardly used in planetary rovers due to the heavy weight and high power consumption and to the authors knowledge, there exists no LiDAR sensor qualified for planetary rover space missions. Other notable work in Boukas, Gasteratos, and Visentin (2018) and Hwangbo, Di, and Li (2009) proposed solutions based on matching networks of landmarks or regions of interest that are traceable both from ground and orbital images. A global network is calculated offline from orbital images around the landing site ellipse, while the local network is calculated along the traverse.…”

“…Towards this end, in the context of this PhD thesis, we have managed to create a new pipeline for a system that will be able to extract semantic landmarks and autonomously localize a rover on a global reference frame. Moreover, we have systematically studied every aspect of such a system producing noteworthy results [14,[65][66][67][68][69][70][71][72][73]. Our global localization system (Fig.…”
