Best Cheap Drones for Surveying

1.DJI Phantom 4 RTK

The DJI Phantom 4 RTK (Real-Time Kinematic) is an enterprise version of the popular prosumer DJI Phantom 4 Pro. The Phantom 4 RTK gets a hat up the top of it to fit in a real-time kinematic (RTK) positioning system, which combines with its other GPS, GLONASS, Galileo and BeiDou positioning systems to offer extreme positioning accuracy. It is a Phantom 4 quadcopter that is designed to deliver centimeter-level accurate mapping that can be extremely useful for surveying, construction sites, and inspections.  The Phantom 4 RTK can achieve 1cm+1ppm RTK horizontal and 1.5cm+1ppm RTK vertical positioning accuracy.

In addition to the real-time kinematic (RTK) receiver, the Phantom 4 RTK can achieve such accuracy due to DJI’s TimeSync system and the gimbal camera’s calibration process. The camera is the same one that’s on a standard Phantom 4, but with the Phantom 4 RTK, each camera has its radial and tangential lens distortions measured. They are added to the metadata of all captured images, allowing for accurate post-processing that account for the distortions.

The Phantom 4 RTK can perform mapping duties in real-time and When mapping, pilots can utilize the Photogrammetry and Waypoint Flight modes in the GS RTK app. This gives mapping-specific functionality, such as selecting flight paths and directly loading KML area files. Combine it all and you have an enterprise-level mapping solution that can be used right out of the box.

Phantom 4 Pro V2 was designed to improve on the earlier Phantom 4 models, Phantom 4 pro is cost-effective, easy to use, durable, and dependable. Phantom 4 Pro V2 with its high specification, allows for the creation of professional aerial photography and film and makes it very suitable in almost every sector, from marketing to aerial surveying and creating 3D maps using UAV photogrammetry.  The Phantom 4 Pro is the best known RTK drone for surveying because it just works. The main advantage of the Phantom 4 RTK is that you will need to shoot fewer ground control points because of the onboard GNSS module and the DJI base station. The Phantom 4 Pro has consumer-grade GPS with GLONASS and so you need a lot of ground control in order to anchor and correct the model. It gives 0.1′ vertical accuracy as it has a 1-inch 20MP CMOS sensor and a mechanical shutter, eliminating rolling shutter distortion.

Many companies develop applications such as DroneDeploy for UAV 3D mapping, which can be used with the DJI Phantom 4 Pro V2.

Other companies, such as DRONExpert have designed a special mount where a drone thermal camera can be fitted on the Phantom 4 Pro V2.

4.YUNEEC H520 RTK+ E90

security, construction, surveying and mapping DronesThe Yuneec h250 is built for inspection, law enforcement, security, construction, surveying and mapping application in addition to offering cinematic imaging payload systems. The Yuneec H520 is very comparable to the DJI Phantom 4 Pro, with the added benefit of being run on open-source software. The E90 1” sensor camera is recommended for surveying. Further, Yuneec is an Intel portfolio company, so it can be used when DJI products are not allowed for security reasons. H520 with real-time kinetics (RTK) technology is able to stand in the air with centimeter accuracy, enabling extremely precise, repetitive photos, faster 3d mapping and more accurate inspection flights.  The software takes a little more experience to use than DJI’s, but it is a totally capable surveying drone.

Surveying Drones in NigeriaFixed-wing drones have always been a niche in the drone surveying market, but if you fit into that niche, they provide immense value. If a typical site is above 50 acres, then using a fixed-wing aircraft will save a lot of time, and the senseFly eBee X is the best of the fixed-wing aircraft out there.  The sensefly S.O.D.A 3D camera is suitable for 3D construction in vertical environments, the Aeriax and Duet T for creating geo-accurate maps. We recommend the senseFly eBee X with RTK/PPK Activation paired with the senseFly S.O.D.A. 1-inch 20MP sensor. With high quality, swappable payloads, the data quality is great. The only downsides are the price, and the inability to fly small sites or at low altitudes — fixed-wing aircraft just cannot fly low and slow.

  • Maximum flight time – 90 min
  • Vision accuracy- 3cm
  • Covers up to 500 ha at 400ft
