Do I still need to collect Base GNSS data with the ROCK Ultra?
Yes! Data from the ROCK Ultra still needs to be processed using the PPK workflow in ROCK Desktop, which requires Base GNSS data collected before, during, and after your survey.
Can I collect SLAM or mobile data with the ROCK Ultra?
No, the ROCK Ultra is designed for airborne data capture only.
What altitude limits do I have when flying the ROCK Ultra?
You can collect LiDAR data with the ROCK Ultra up to an altitude of 500 meters (1,640 feet). However you will still need to follow any airspace restrictions or government regulations for the maximum height you can fly your drone.
What program should I fly the ROCK Ultra with?
Using the ROCK Pilot app is preferable as all steps like system initialization, data collection start, calibration flights, and data collection completion are built into the program. Additionally ROCK Pilot allows you to update the Point Rate and Rotation settings depending on your survey area and goals. However, you can still fly the ROCK Ultra with a program like DJI Piot, you will just need to manually start and stop data collection using the 1 button method, and manually fly your calibration flights.
What is the maximum speed I can fly the ROCK Ultra with?
This is going to depend on your survey goals. During testing of the ROCK Ultra, we have flown at a maximum speed of 15 meters per second and still were able to produce a high quality point cloud and surface from the collected data. If you wish to discuss the best mission parameters for your survey, you can always reach out to the ROCK Customer Success Team (support@rockrobotic.com) to discuss in greater detail.
Do I still need to capture calibration flights before and after my survey?
Yes! Here's the calibration data that needs to be collected:
- 30 second static collection before take off.
- High speed kinematic flight after take off (minimum of 5 seconds duration at a speed of 10 meters per second or greater).
- Figure 8 calibration.
- High speed kinematic flight after the survey is complete (minimum of 5 seconds duration at a speed of 10 meters per second or greater). This can be done as the "return to home flight."
- 30 second static collection after landing.
What drones can I fly the ROCK Ultra with?
The ROCK Ultra can be configured to fly with any drone that can support the 1.4 kilogram payload.
Can the ROCK Ultra be set up on a plane or helicopter for data collection?
Yes! ROCK recommends that an additional damper is used to reduce vibrations on the ROCK Ultra.
