With the SLANTRANGE 3P - you can capture huge amounts of data in a single flight. This is thanks to the onboard processing unit, which only requires a 20% image overlap. Contrast this with previous NDVI sensors, which required an 80% overlap, and you can see just how much time and money can be saved by investing in the SLANTRANGE 3P.

This NDVI solution is also designed to be easily integrated with an array of flying platforms including popular models from DJI. For more information on compatibility and potential use cases for this aerial multispectral sensor give us a call on 0191 296 1024 or email






SlantView is the analytics toolset from SLANTRANGE that analyses raw data from airborne sensors and collates it into valuable information for farmers. SlantView was architected from the start to deliver the highest value information, and that includes two fundamental differences from other analytics packages: 1) Diverse and customisable information types can be tailored to the user’s immediate needs through advanced computer vision and machine learning techniques; 2) Those information layers can be delivered in a matter of minutes

There are three service levels of SlantView available - see below for what you get with each package:

    • SlantView Lite – (FREE) This default version comes with the 3p as standard with image pre-processing and calibration for analysis with 3rd party applications
    • SlantView Basic – (Contact for Pricing) The basic level comes with all the capabilities of 'Lite' plus access to Vegetation Stress maps and multiple NDVI products allowing for as little as 20% overlap and rapid in-field processing
    • SlantView Pro – (Contact for Pricing) This is the complete suite of SlantView analytics tools which combine spectral imaging with powerful computer vision and machine learning tools



The SLANTRANGE 3p's design elements run together through its integrated hardware/software architecture to deliver the most accurate measurements available for small aircraft:

  • An integrated solar spectrometer for frame-to-frame radiometrically accurate reflectance measurements
  • Individual lens characterization for precise de-warping and de-vignetting
  • Optimised algorithms for dynamic cross-channel registration
  • Smart Filtering, which selectively samples scene elements to avoid the contaminating effects of background soils, shadows, specular reflections, or other noise sources.


What resolution are the cameras?

The resolution is 1280 x 1024.

What is the Ground Sample Distance (GSD) of this sensor?

4.8cm/pixel @ 120m AGL. The resolution will vary depending upon the height of your aircraft.

Does the sensor have built-in storage?

Yes - there's a 64gb removable SD card (which can record for around 4 hours flight time)

How do I use the Imagery from the 3P?

Simply remove the SD card and upload them to your PC or Mac. Use the SlantView software to process the images and data you've captured.

How is the Sensor powered when being used with a drone?

The sensor can accept 9 VDC - 36 VDC and usually draws ~11W. 

Can I use a Flight Planning software with the 3P?

Yes - DroneDeploy is supported.

Does the SlantRange 3P need a gimbal?

No - it's designed to be flown facing straight down.

I just bought a DJI Mavic Air Heliguy - I had looked at getting it from a number of different online stores, but Paddy answered a few questions I had really quickly, was able to make sure that I received my order the next day, and made the buying experience really personal, which is often hard when buying online. I would thoroughly recommend purchasing from Heliguy based on this high level of service.
