    Abstract: According to an aspect, an apparatus may obtain map data associated with a tunnel system of an underground worksite, obtain a start position and an end position for a mining vehicle configured to operate in the tunnel system; obtain vehicle information comprising at least kinematic restrictions and space restrictions associated with structural body members of the mining vehicle and a movable work device of the mining vehicle, the kinematic restrictions comprising movability limits of the movable work device; and determine at least partly based on the map data, the start and end positions, and the vehicle information, a collision free continuous route between the start and end positions for the mining vehicle, the collision free continuous route having at least one collision free position for the movable work device within the movability limits of the movable work device along the collision free continuous route.

    Abstract: The disclosed embodiments include a rotating survey tool. The rotating survey tool includes a first sensor array that in operation collects a first set of survey measurements during a downhole drilling operation. Additionally, the rotating survey tool includes a second sensor array directly coupled to the first sensor array that in operation collects a second set of survey measurements while a drill bit drills during the downhole drilling operation. Further, the second set of survey measurements has a greater base accuracy than the first set of survey measurements.
