Abstract: Navigation of an agent, such as a person with blindness or low vision, in an unfamiliar environment poses substantial difficulties, even in scenarios where prior maps, like floor plans, are ...

Unlike on Earth there aren’t dozens of satellites whizzing around Mars to provide satellite navigation functionality. Recently NASA’s JPL engineers tried something with the ...

Abstract: It is challenging to ensure both high accuracy and low complexity when localizing radiation sources. To address this challenge, we propose two novel methods leveraging time difference of ...

NASA has mapped every inch of Mars, so positioning consists of the rover looking for geologic features and then comparing that to the distance that the rover has traveled. Older rovers had to stop and ...
