Drone surveys have become a key tool for acquiring accurate topographic data in a short time. But to achieve professional-level accuracy, you need a system capable of correcting GPS signal errors in real time. That\u2019s where the RTK base comes into play. Until recently, these technologies were complex and reserved for expert surveyors. Today, thanks to intuitive solutions like ProTRACK<\/strong><\/a>, even less experienced professionals can achieve centimeter-level results with ease. If you\u2019re looking for a lightweight, affordable, and easy-to-use RTK GPS<\/strong>, this guide will help you understand how ProTRACK<\/a> works and why it\u2019s the right choice for your drone surveys.<\/p><\/blockquote>\n\r\n\r\n<\/a>\n

If you’re thinking about using a drone for topographic, photogrammetric, or agricultural surveys, you may have already encountered terms like RTK, GNSS base, differential corrections, or centimeter-level accuracy<\/strong>. And maybe you\u2019ve asked yourself: \u201cDo I really need all this equipment to work effectively?\u201d<\/em><\/p>\n

The answer is yes \u2014 but with good news: today, there are lighter, more intuitive, and accessible solutions<\/strong>, like the ProTRACK<\/a> GPS by Analist Group, which allows you to achieve the same professional precision even if you\u2019re not an expert surveyor.<\/p>\n

In this article, you\u2019ll discover what an RTK base for DJI drones<\/strong> is, what it\u2019s used for, and how you can use it easily.<\/p>\n

Why a drone alone isn\u2019t enough for accurate surveys<\/h3>\n

The latest-generation drones, such as the DJI Mavic 3 Enterprise RTK or Matrice 350 RTK<\/strong>, are powerful tools: they capture ultra-high-resolution photos, cover large areas, and enable the creation of 3D terrain models, orthophotos, and digital maps.<\/p>\n

However, there\u2019s a limitation: the standard GPS position received by the drone from satellites can have errors of several meters. That\u2019s fine for a video or tourist photo \u2014 but not accurate enough for drone and GPS-based surveys.<\/p>\n

What is an RTK base and why you need one<\/h3>\n

To obtain centimeter-level precision, you need a system called RTK (Real-Time Kinematic). This system is based on two GNSS receivers:<\/p>\n
