Unmanned Aerial Vehicles - DJI M300

We fly the DJI Matrice M300 which is the top-of-the-line Search and Rescue, and Industrial Inspection unmanned aerial vehicle currently available. The ultimate flexibility of this platform comes from the reconfigurable gimbal configuration allowing a wide range of payloads to be carried to meet specific client needs. The M300 UAV:

Has a flight duration of up to 55 minutes depending on payload. Use of hot swappable batteries and with flight turnaround of 3-5 minutes facilitates continuous operations.

Is suitable for operations in harsh conditions:

-20C to 50C
IP45 Water and Dust Ingress rating
Operational Ceiling of 7000m
Wind rating of 54kmph

Can perform a safe landing on 3 motors, increasing its operational safety near people.

Is able to be operated with two controllers simultaneously, facilitating either:

multiple remote pilots in command for expansive operations; or
the splitting of the role of Pilot and Search Operator to provide an optimised workflow.

We can provide video streaming:

Local Streaming to the primary or second controller and display on a standalone HDMI Monitor; or
live stream to third parties via the AWS Cloud.

Has 25km certified Automatic Dependent Surveillance Broadcast (ADS-B) Receive capability on board to track air traffic operating in the airspace.

Features many redundant systems to maximise the safety of the aircraft and those that are operating near it. These include Inertial Management Units, Barometers, GPS units and Antennas, Compasses, Beacons, Vision and Time of Flight Sensors and Flight Batteries.

Survey and Inspection Accuracy

Accuracy when constructing maps and 3D models is imperative. The quality of the results produced are a function of the Technology used and the workflow executed. It is impossible to increase the accuracy bad data and it is therefore imperative that the most accuracy if a consideration through the the entire process of data capture and data processing.

Data Capture

At PHIRE-1 Solutions Pty Ltd, we use a range of technologies to ensure that the work we provide to clients meets their stringent demands. The choice of a UAV that supports Real Time Kinematics and the operational use of Ground Control Points are crucial to the quality of deliverables as they provide the analyst with three means of validating the solution.

Real Time Kinematics (RTK)	Utilising an RTK solution (UAV + Base Station) ensures that the operator has a basic accurate solution from which to confirm his plan execution. It also provides the Analyst with a perspective on the overall accuracy of the solution when compared with the other tools used in the back office.
Post Processed Kinematics (PPK)	By building a PPK solution, the Analyst is able to get a second view of the accuracy of the data that has been captured. There should be no significant difference between the solutions.
Ground Control/Check Points (GCPs)	Ground Control Points are fed into the mathematics of the solution to increase its accuracy. Ground Check Points provide a further means of checking the accuracy of the overall solution.

Back Office and Analytics

Once the sensing phase is complete, PH1S will provide data that meets your specific requirements in the form of GIS objects (Vector or raster layers, TIFFs etc), orthographic images and 3D Models, or just plain JPEGs.

PH1S is equipped to provide rapid mapping solutions in the field using Pix4DReact or Pix4DField. 3D models are provided using DJI Terra and/or Pix4DMapper. 3D objects can be provided in either OBJ or FBX format. For Point Clouds, PH1S can provide LAS and other format solutions.

PHI1S utilises a range of different products to construct our solutions.

Pix4D Mapper is used for construction of Othographic maps and 3Dimensional Models

Pix4D Fields is a mobile application that is used for generating orthomosaic images of agricultural and other land. It is also used to generate indicies that can identify issues such as poor irrigation and crop infestation in the agriculture industry.

Pix4D React is a mobile appliciation that is used to rapidly generate Emergency Services orthographic images in the field to assist wiith the management of incidents.

Terra Solid is our tool of choice for the editing of point clouds to generate high quality Digital Surface, Digital Terrain and Digital Elevation Models.

UAV Sensors

DJI H20T - Inspection and Search & Rescue Camera System

Remote Piloted Aircraft are of limited use without high quality Sensors, and we have available the top-of-the-line DJI H20T Quad Sensor which is most suited to Search and Rescue, and Inspection related work.

The H20T has the following sensors available in the one package:

12 Mega Pixel Wide Angle Camera.
20 Mega pixel Zoom Camera with 23x Optical and 200x digital zoom.
A Radiometric Thermal Camera.
A Laser Range Finder; and
Projected location technology to pinpoint sighted objects for ground search teams.

DJI Zenmuse P1 - Photogrammetry Camera

The DJI Zenmuse P1 is the top-of-the-line photogrammetry camera for the DJI M300 UAV. It integrates a full-frame sensor with interchangeable fixed-focus lenses on a 3-axis stabilized gimbal. Designed for photogrammetry flight missions, it takes efficiency and accuracy to a whole new level.

It features:

Accuracy of up to 3cm Horizontally and 5cm vertically.
A full-frame sensor capturing 45Mega pixels
Raw or JPEG format capture.
A 3 axis stabilised gimbal.
A global mechanical shutter to avoid motion blur.
Oblique and Smart Oblique Capture modes facilitating high quality 3D Model generation

With this camera/UAV combination, more information can be captured per flight while maintaining a small ground sampling distance.

DJI Zenmuse L1 Lidar

The L1 Lidar is our preferred tool for capturing point clouds used in the construction of Digital Surface, Digital Terrain and Digital Elevation Models. It is also a support tool for the construction of 3D Models. Lidar has numerous advantages but the primary benefit is that it is able to penetrate the vegetation canopy to provide returns from the underlying surface. The density of points is also substantially greater than that generated through Photogrammetry. The L1 forms a complete solution that gives you real-time 3D data throughout the day, efficiently capturing the details of complex structures and delivering highly accurate reconstructed models.

The L1 Features:

An Integrated Lidar module, an RGB camera for Point Cloud Colourisation, and a high-accuracy IMU.
Vertical Accuracy: 5 cm / Horizontal Accuracy: 10 cm.
A point rate of 240,000 pts / second.
Three returns and a detection range of 450m; and
The RGB camera has a 1inch 20Mega pixel CMOS detector and includes a Mechanical Shutter to remove motion blur.

The L1 generates a substantial amount of data and we utilise the TerraSolid software platform running under the Spatix CAD environment to manage it. Terra Solid also provides the tools needed to manipulate the point cloud data.

Micasense Altum-PT Multispectral Camera

The Increasing demand placed on agricultural land represents an ongoing challenge to farmers. The technological advances in Precision Agriculture are playing a key role in improving the efficiency of large farming operations and multispectral sensors are a clear example. The data captured by drone-based multispectral sensors can make operations more efficient by providing information that allows for better use of resources and more localized applications.

The Micasense Altum-PT Multispectral Sensors features:

Separate Red Green and Blue Sensors coupled with Red Edge and Near Infrared Sensors in a single unit.
A 12 Mega pixel Panchromatic Camera.
3.2Mega pixels per Multispectral band (Red, Green and Blue).
320x256 pixel Flir Bosun 320 Infrared Sensor; and
Ground Sample Distance of 5cm per pixel at 120m for the Multispectral Bands (Red, Green, Blue)

The Micasense Altum-PT is the leading Multispectral solution in the market at present. When coupled with the Pix4D Fields software package and QGIS Spatial Database , the overall solution that we bring to the table stands out from the crowd.
