We’ve explained the different types of heights in the tutorial Ellipsoidal, Orthometric, and Geoid heights, and what they mean for your work. When taking measurements, you might find that the positional information appears accurate, but the height may not be correct. This error could arise from forgetting to input the height of your pole. Alternatively, […]

In the context of GNSS and GPS, we often encounter terms such as heading, course, track, yaw etc. This can be confusing at times because they are frequently (incorrectly) used interchangeably in conversations. Heading By definition though, heading determines the direction in which a vehicle, a boat or a plane is facing. In GPS receivers

Are you navigating the complex world of RTK receivers and wondering which option is the best for your needs? Delve deep into the technical aspects of dual band GNSS/RTK receivers, focusing on a comprehensive comparison between the L1L2 and L1L5 models. Is L1/L5 really cheaper then L1/L2? Does L1/L5 outperform L1/L2? Should you switch to
L1+L2 vs L1+L5: Which dual-band GNSS RTK receiver is better today? Read More »
Not sure if you need a dual-band or triple-band GNSS receiver? Our video breaks it down simply. We cover the basics and then jump into how each type of RTK receiver works best for farming, surveying, drones, robotics, or when deploying a base station. Dual-band vs. triple-band: What’s different? A look into what we do

What is ROS? ROS (Robot Operating System) is a framework designed for building robotic systems. It is not an actual operating system in the traditional sense, but rather a meta-operating system that runs on top of a host operating system (such as Linux). It provides a middleware layer that abstracts the hardware and offers a

Latest generation RTK receivers can provide you with very accurate position at affordable cost. But investing on your own RTK receiver it’s still a big decision. In some countries, RTK corrections are available for free and this helps. But if you are unlucky and there is no free national RTK network, or simply there’s no
Do you need absolute accuracy or relative accuracy is enough? Read More »
It might have happened to you: your RTK receiver is in RTK FIXED, reporting centimeter precision and you are happily doing very accurate measurements. You go back to your desk and compare your results with the measurements from another day or from another person. And you get a big surprise: there is an offset! It’s
Sometimes a video is better than 1’000 words. We prepared a new 10-min videotutorial to explain the basics of RTK and how it is possible to achieve centimeter level accuracy with GNSS. Thanks for watching and we hope today you learn something new!

Table of contents Many customers get confused with the different heights (altitude) reported by their GNSS receiver.In this post we will show the concept of each one with plain words (we apologize to all surveyors and scientists that read this post). Ellipsoidal height: Planet earth shape is simplified as a rugby ball (ellipsoid).Ellipsoidal height is

Dear followers, If you own a Medium Range (MR), Long Range (LR) and eXtra Long Range (XLR) radios or kit, you might have noticed that all specification are mentioning “RF line of sight”. But what does this actually mean, how does it differ from “Visual line of sight”? Digi has written a very good document about
