Top 10 questions about Parrot Bluegrass
How to calibrate Parrot Bluegrass
It is advisable to calibrate the drone before each flying session with the FreeFlight Pro or Pix4Dcapture app. If the app displays a window requesting drone calibration, follow the steps shown on the screen. You can also start the calibration of the drone manually.
With FreeFlight Pro:
1. Select Parrot Bluegrass in the FreeFlight Pro app.
2. Press the Calibration button in the information page on the drone.
3. Follow the on-screen animation. > The animation disappears when the calibration is completed. You can then start the flight plan on Pix4Dcapture.
With the launch of the mission, a "Take-off check-list" control window checks the flight settings. If a calibration is needed, you will be prompted to calibrate the drone by following the steps on the screen.
Select Parrot Bluegrass in the FreeFlight Pro app.
Press the Calibration button in the information page on the drone.
Follow the on-screen animation to calibrate your drone.
How to update Parrot Bluegrass
Parrot Bluegrass can be updated in several ways:
using the FreeFlight Pro app: a notification appears when a new software version is available.
2. using the Pix4Dcapture app: a notification asking you to download the latest available version appears in the drone's checklist.
3. using a USB stick: by downloading the version on the website of the support page.
How does Parrot Bluegrass work?
Consult the user guide and the support section to find out how Parrot Bluegrass works.
What are the types of crop with which Parrot Bluegrass works?
Parrot Bluegrass provides NDVI data for all types of vegetation. The analysis is optimized for wheat, barley, maize, canola and for golf courses.
With a low altitude of flight, Parrot Bluegrass is the ideal monitoring solution for fruit crops such as strawberries, lemons, vines and grapes.
What are the spectral bands of the monochrome cameras?
Parrot Sequoia+ consists of a multispectral sensor and a sunshine irradiance sensor integrated in Parrot Bluegrass.
Parrot Sequoia+ can be used to obtain images of agricultural plots in several spectral bands that measure the state of the vegetation:
Green (550nm wavelength, 40nm bandwidth)
Red (660nm wavelength, 40nm bandwidth)
Red-edge (735nm wavelength, 10nm bandwidth) and near-infrared (790nm wavelength, 40nm bandwidth).
The photos taken can then be analyzed using various software programs. They can be used to make indexed maps (NDVI, NDRE, etc.) and make recommendations regarding nitrogen fertilization.
How to recover data with an SD card
What software can be used with Parrot Bluegrass?
Parrot Bluegrass can be used with Airinov First, Airinov First +, FreeFlight Pro, Pix4DAG and Pix4Dcapture.
How many acres can be covered by Parrot Bluegrass in a single flight?
The battery life of Parrot Bluegrass delivers 25 minutes of flying time. In a single flight, it is possible to cover the following area:
- Up to 74 acres at an altitude of 70 m/230 ft per battery.
Are options like Follow Me, Magic Dronies or Flight Plan available with Parrot Bluegrass?
How to calculate the reflectance
Is the radiometric calibration mandatory? How is the calibration done?
Calibrating Parrot Sequoia+ is an important step. The multispectral sensor flashes purple when calibration is required.
1. Turn the drone on the X-axis until the indicator light of the multispectral sensor flashes green.
2. Turn the drone on the Y-axis until the indicator light of the multispectral sensor flashes cyan.
3. Turn the drone on the Z-axis until the indicator light of the multispectral sensor changes color.
> NB: Once the calibration is complete, the color of the multispectral sensor indicator light varies according to Parrot Sequoia+'s status. For example, if the memory of the multispectral sensor is full, the indicator light will flash yellow
