sun-synchronous navigation
This is from CMU, actually from a 2001 exploration in the Canadian arctic. But in terms of interest in exploring other planets, I found it very interesting. What is sun-synchronous navigation? Sun-synchronous navigation is a technique that involves tracking the sun while exploring terrain. It is accomplished by traveling opposite to planetary rotation and in synchrony with the sun to always remain in sunlight. Robotic explorers on the planets and moons can employ sun-synchronous navigation to maintain continual exposure to sunlight to acquire the power necessary to sustain operation for extended periods of time. By setting their speed appropriate to their latitude and navigating to avoid shadows cast by local terrain, these solar-powered robots will be able to operate continuously. Furthermore for some missions, by following the dawn (specifically by lagging...
