About this file
This notice of intent describes a planned sole source procurement by the U.S. Geological Survey for a LiDAR scanner system. The system must be compact for mounting on aircraft or drones, eye-safe, and capable of high measurement rates through vegetation at ranges up to 700 meters. It requires integrated INS/IMU and GPS with specified accuracies. The solicitation will be for a Riegl USA scanner meeting attached salient characteristics. Responses are due by June 17, 2022 and award will be made using simplified acquisition procedures. The purpose is to satisfy requirements to consider responses for a system designed for the USGS' aircraft and drones to support volcanic monitoring at Hawaiian Volcano Observatory.

Volcano Science Center, Hawaiian Volcano Observatory (HVO) LiDAR scanner with integrated IMU/GNSS
Salient Characteristics
Specifications meet or exceed the following criteria:
Compact size/weight for external mounting to MD 500 helicopter or DJI M600 Uncrewed
Aircraft Systems (UAS):
Must have dimensions that allow mounting on a DJI M600 UAS (generally less than 620 mm x 320 mm x 505 mm).
Maximum weight with IMU: 6 kilograms or less – realistic limit for M600 UAS to maintain usable operational range.
Eye-safe Class 1 laser product, to avoid negative impacts to the public and local wildlife.
Scanning specifications necessary for effective measurements of young lava flows and volcanic terrain – including near-vertical crater walls – at such rates that can also see bare-earth surfaces through thick tropical vegetation:
Nadir/forward/backward scan patterns.
Effective measurement rate of at least 1,200,000 measurements per second.
Laser pulse repetition rate of at least 1.5 MHz (1500 kHz).
Operation at near-infrared wavelength of 1550 nanometers.
Ranging based on full-waveform capabilities.
Maximum scan speed: 300 lines per second or better.
Minimum accuracy and precision: 10 millimeters or better.
Minimum field-of-view: 90 degrees.
Measuring range of at least 700 meters for low-albedo (as low as 20%) targets at
>100 kHz laser pulse repetition rate (PRR).
Integrated inertial navigation system (INS) / inertial measurement unit (IMU) and
GPS/GNSS system for seamless operations, with the following specifications:
Minimum roll/pitch and heading accuracies: 0.05 degrees or better.
Minimum horizontal and vertical positional accuracies: 10 millimeters or better.
External INS/IMU sensors directly interface with scanner.
Integrated mirrorless digital camera system with calibration and mounting hardware with capability to interface with at least 2 external cameras.
Shipping case to accommodate the scanner with INS/IMU, GPS/GNSS and camera system attached.
Raw data that includes integrated laser scan data, INS/IMU values, and GPS/GNSS values.
Integrated software package and online waveform processing capabilities, to enable rapid turnaround of datasets to HVO personnel and emergency managers during volcanic eruption responses, with a tested workflow and usable end products. The software package and processing capabilities must be compatible with those of the Army Corps of Engineers’ Cold Regions Research and Engineering Laboratory, a partner agency of the Hawaiian Volcano Observatory on various LiDAR projects, and whose expertise and engineering capabilities will be heavily relied upon for setup and operation of this system.
