Does Parrot SQ+ have the same software than Parrot Sequoia? Can I transform my Parrot Sequoia into a Parrot Sequoia+ ?. 2 Why is there a target with my Parrot Sequoia+?. 2 Which wavelengths are captured by Parrot Sequoia+?. 2 What index can be measured by Parrot Sequoia+?     1.       What is the purpose of using Parrot Sequoia+?   By capturing images of crops from the sky, the multispectral sensor provides the user with unrivaled information on the status of their crops. This information will help farmers optimize the management of their plots. This information can concern the health status of the crops, the density of the vegetation …   2.       What are the technical difference between Parrot Sequoia and Parrot Sequoia +?   The Parrot Sequoia + and the Parrot Sequoia have exactly the same hardware. The Parrot Sequoia+ has a specific factory radiometric calibration: an extensive calibration based on more than 1200 images has been performed in the factory for each sensor. When using Pix4D software for processing the images captured by a Parrot Sequoia+, the use of a radiometric calibration target is not required. Parrot Sequoia+ combined with Pix4D software provides absolute reflectance values without the need of a radiometric calibration target.   With Airinov platform or others processing software, a radiometric calibration target is needed to have absolute reflectance values for both Parrot Sequoia and Parrot Sequoia+   3.       Can Parrot Sequoia+ be used with others software?   Yes. However the results are optimal when using Pix4D software.   4.       Does Parrot SQ+ have the same software than Parrot Sequoia?   Yes, the same firmware is used for Parrot Sequoia and Parrot Sequoia+. Parrot Sequoia+ has a specific factory calibration to be compatible with the targetless workflow with Pix4D.   5.       Can I transform my Parrot Sequoia into a Parrot Sequoia+ ?   The Parrot Sequoia cannot be transformed by the end-user into a Parrot Sequoia+. It needs an intensive factory calibration.   6.       Why is there a target with my Parrot Sequoia+?   The radiometric calibration target is included with the Parrot Sequoia +. The target is used to measure absolute reflectance values when using another processing software than Pix4D. By using Pix4d to process Parrot Sequoia+ images, the user experience is enhanced and the errors are reduced.   7.       Which wavelengths are captured by Parrot Sequoia+?   Parrot Sequoia+ has four different global shutter sensors which capture the images in 4 different bands:           - Green: 550nm +/- 40nm           - Red: 660nm +/- 40nm           - Red border: 735nm +/- 10nm           - Near infrared: 790nm +/- 40nm 8.       What index can be measured by Parrot Sequoia+?   Parrot Sequoia+ can compute dozens of index. Some of them are: NDVI, GNDVI, NDRE, ARVI2, WDRVI…

What is the cost of Sequoia, and what does a purchase include ? The Sequoia recommended package costs $3,500.00 USD. It includes the multispectral camera, the Sunshine sensor, power & trigger connectors to interface between host aircraft and the two sensors, a 32GB SD card, three different mount for the Sunshine sensor, a protection lens for the main body and a soft cloth to clean the lenses. Where can I purchase a Sequoia? You can buy Sequoia alone on the Parrot online store. Sequoia is also sold by the four different companies of the Parrot Group, each one selling the package alone or integrated in their solutions.

Can Sequoia be integrated with a SenseFly’s eBee Autopilot software e-Motion? Yes. The Sequoia is fully compatible with e-Motion. What is the data output format? Is it one image for each camera or a composite? The data is saved, on the internal memory or on the SD card, as a RAW 10-bit TIFF file for the 4 bands and as a JPG for RGB camera. It stores 5 images for each picture (one per band + RGB). Are there some mounts to integrate Sequoia on specific drones? Three different mounts are provided in the package for the sunshine sensor. At this time we are not selling mounts that go with the main body.

Sequoia is a state of the art multispectral sensor for agriculture. Its development has been made with four major features in mind: sharpest accuracy, smallest size, lightest weight and absolute ease of use, allowing for Sequoia to be carried by any drone. With better precision than Satellite imagery and higher flexibility than manned aircraft solutions, the Sequoia sensor can provide very accurate reports of plants conditions. Agronomists, growers and farmers can benefit from its simplicity and flexibility to set up a regular monitoring of their crops.   Its embedded cutting-edge technologies include four narrowband filters - capturing images that are highly sensitive to plants biological status - and a RGB camera to keep a true vision of the field. The collected data provide very reliable information for cultural decision making. In addition, the Sequoia sensor comes with an included calibrated Irradiance sensor that captures the incident light. It allows for comparisons and analysis of images captured in different lighting conditions.   Sequoia sensor was born from the collaboration of four international companies specialized in agriculture and professional drones. Lead by Parrot, these companies provide multiple solutions involving the Sequoia sensor.   Sensefly : eBee Ag, the precision agriculture drone The SenseFly’s fixed-wing eBee Ag is the precision agriculture drone used by farmers and consultants the world over; the highly durable and fully automatic eBee Ag is the next logical step in your operation’s evolution.
