About this file
This document outlines technical specifications for a light detection and ranging (LiDAR) sensor and components to be mounted on a DJI Matrice 600 unmanned aerial system for the Department of the Interior US Geological Survey Office of Acquisitions and Grants. The LiDAR sensor must meet or exceed specified performance characteristics including precision of less than 2.5cm, accuracy of less than 3.0cm, integrated inertial measurement unit and GPS, eye-safe laser wavelength, field of view, point rate, echoes per measurement, laser beam divergence, integrated 20MP RGB camera, operating temperature range, weight of less than 1.65kg including camera and battery, physical dimensions, standalone battery power for minimum 1 hour of autonomous operation including two batteries and charger, USB flash storage drives, GPS antenna and cable, boresight calibration and angle correction certificate, software for post-processing GNSS, IMU and raw LiDAR data to specified accuracies, one year warranty and maintenance on all hardware and software, installation and training, shipping and associated fees, and backpack for carrying.
The related federal contract opportunity is solicitation number 140G0123Q0273 for a LiDAR scanner and components mountable on a DJI Matrice 600 for the Department of the Interior US Geological Survey Office of Acquisitions and Grants.

Attachment 1 - LIDAR Sensor Requirements
Meet or Exceed the Following:
1. Interface with existing sUAS platform (DJI Matrice 600) including mount for M600
2. Light Detection and Ranging (LiDAR) Scanner with integrated Inertial Measurement Unit (IMU), GPS, and
RGB Camera for direct georeferencing and colorization of lidar point cloud (LPC)
3. Wavelength: 905nm Class 1 Eye Safe Laser
4. Scanner Precision: equal to or less than 2.5cm – This is measured as the mean value of absolute elevation differences between 2 flight lines recorded in opposite directions over a nadir-located 40m² hard surface area. This specification is the average of three data collects flown at 10m/s at flight elevations 60m, 90m and 120m AGL. (Precision, also called reproducibility or repeatability, accounts for the variation in successive measurements taken on the same target.)
5. Scanner Accuracy: equal to or less than 3.0cm – This specification value is obtained by averaging the accuracy from 3 flight levels @ 60, 90 and 120m AGL when flown at 10m/s. At each flight level, the accuracy is considered as the RMSE value of the elevation differences between targets and the point cloud extracted from 2 flight lines recorded in opposite directions. Validation targets are located within a 40m wide corridor centered along the flight line axis. (Accuracy is the degree of conformity of a measured position to its actual (true) value.)
6. IMU Geospatial Accuracy after post processing of =< 0.02 m – 0.05 m
7. Field of View: => 70 degrees Horizontal / => 77 degrees Vertical
8. Equal to or greater than 240,000 measurements / second (Point Rate)
9. Equal to or greater than 3 Echoes per measurement
10. Laser beam divergence =< 0.28° (Vertical) × =< 0.03° (Horizontal)
11. Integrated 20MP RGB camera with a global shutter for co-collecting imagery with lidar data for colorizing the lidar point cloud
12. Operating Temperature Range: equal to or better -4 to +104 degrees F / -20 to +40 degrees C
13. Weight equal to or less than 1.65 kg / 3.64 lbs including camera and battery
14. Physical outside dimensions =< 22.7 cm (Length) x 10.4 cm (Width) x 12.8 cm (Height)
15. Stand-alone Battery Power and Operation with no electrical connection to UAV
16. Battery Power and Data Storage for a minimum of 1 Hours of Autonomous Operation
17. Includes at least (2) batteries and (1) charger
18. Includes at least (2) USB flash storage drives
19. Includes at least (1) GPS antenna and cable
20. Payload must be boresight calibrated and provide an angle correction certificate.
21. Includes Software for Post-Processing GNSS and IMU data for accuracies stated above
22. Includes Software for Post-Processing Raw Lidar data to output an industry standard, geo-referenced, LAS
Point Cloud to the accuracy specifications above, individual strips adjusted, automatically colorized with RGB camera data and terrain points classified as ground/non-ground
23. Minimum 1 year warranty and maintenance on all hardware and software
24. Include installation and training
25. Include shipping and associated fees
26. Include backpack for carrying
