Slide 9: Trials
Trials Trial (v): test (something, especially a new product) to assess its suitability or performance.
Slide 10: Step 1: Training and Govt. Legislation
Step 1 TRAINING AND GOVT. LEGISLATION CASA The legalities of use of the system Overkill of bureaucracy and licensing Easing of instruction due to the RPAS Certified Course Manufacturer training Are we pilots now?
Slide 11: Lesson 1: The Great Drone Unknown
Lesson 1 THE GREAT DRONE UNKNOWN Where did/does it fit in the air according to CASA Original requirement was Private Pilots License – Visual Flight Rules (PPL VFR) Now Remotely Piloted Aircraft Systems (RPAS) certification
Slide 12: Testing
Testing QUESTIONS, QUESTIONS, QUESTIONS…. How will the data impact our processes? Will it become the primary source of survey data? How will the customer react to all the extra information? The first question that was raised was “How long is this new process going to set back the time line in ge
Slide 13: Live ROM Test
Live ROM Test THE CRITERIA THAT WAS TESTED INCLUDED 1. Time taken to conduct the survey 2. Time taken to calculate the volume 3. Level of confidence in the quality of the results 4. Variance of volume calculations from different methodology 5. Safety factor

Slide 16: Tribulations
Tribulations Tribulation (n): an experience that tests one's endurance, patience, or faith.
Slide 17: Expectations, hurdles and obstacles
Expectations, hurdles and obstacles ENCOUNTERING THE UNKNOWN How will it handle a lake environment and extreme weather conditions? What to use as landing and take-off areas? Will it be a distraction to mining personnel? In the planning for the use of the Trimble UX5, two factors loomed large
Slide 18: Expectations, hurdles and obstacles
Expectations, hurdles and obstacles SPEED AND HEIGHT The Trimble UX5, once airborne and on its flight path, travels at a Ground Speed of 83-91kph, and when it comes in to land, the displayed Ground Speed is 68-73kph. So even with the fully laden Trimble UX5 weighing in at only 2kg, significant for

Slide 20: Adjustments made to the camera trigger
Adjustments made to the camera trigger SIMPLIFYING TO ACHIEVE GREATER QUALITY Light Sensor camera trigger. Due to extreme light conditions (caused by salt lake reflection) up to 6% of photos not taken. USB hard wire photo switch. Since swapping to this trigger (approx. 22 months) the photo loss is 0
Slide 21: Learning to fly…….
Learning to fly……. THE OBJECT IS TO STAY IN THE AIR Over 440+ flights completed to date Not every flight has gone according to plan We have trialled, learnt and improved Worked with the agents (HLGS) and manufacturer (Trimble) to improve the performance
Slide 22: The Wedge Tail Eagle
The Wedge Tail Eagle NATURAL ENEMY OF THE UAV Wingspan between 182 and 232 cm (6 ft 0 in and 7 ft 7 in) Weighs between 3 and 5.77 kg (6.6 and 12.7 lb) Length varies between 81 and 106 cm (32 and 42 in) Each pair occupies a home range, which may extend from as little as 9 km2 (3.5 sq mi) to m

Slide 26: Triumphs
Triumphs Triumph (n): Joy or satisfaction resulting from a success or victory
Slide 27: Universal Acceptance
Universal Acceptance THE TRIMBLE UX5 HAS NOW BECOME THE PRIMARY SURVEY TOOL Data quality, both in accuracy and precision, the amount of data capture and refining the process has allowed broad usage of the flight surveys by all departments. They include but are not limited to Weekly open pit survey
