IVIGMSThis LiDAR was developed for planetary rover applications with a focus on situational awareness, mapping and hazard avoidance. Using a novel, patented spinning design, it is able to scan rapidly over a field of view of 360° in azimuth and 45° in elevation. The sensor is random-access, meaning the operator can command any beam trajectory desired. Several pre-programmed trajectories are provided that are tuned to rover-based mission objectives. High-rotation rate scans are employed for situational awareness and hazard avoidance. High resolution (lower rate) scans are also possible for detailed mapping requirements. Hybrid scans provide the best of both worlds employing phase-shifted high rate scans that evolve over time to fill the gaps left in previous passes.



360 LiDAR 1 sec.

1 second scan of a 30x20m high-bay
(~200k pts)

360 LiDAR 10 sec.

10 second scan of a 30x20m high-bay

The sensor can gather range measurements at 200 KHz, which corresponds to a 200m max range, or at 25 KHz with a maximum range of 1km.

The prototype sensor mass is 7.3kg and requires no external power conditioning or processing. External connections are 28V power and Ethernet. Communications are handled with a delivered API or through Neptec’s user interface software (which adds data analysis capabilities).
