Mergin Maps is a field data collection tool built on the free and open-source QGIS which allows you to collect, store and synchronize your data with your team. With Mergin Maps, you can get your QGIS projects into the mobile app, collect data and synchronize it back on the server. In Android, there are two […]

We’ve already detailed the process for connection and configuring u-blox GPS receivers using u-center on Windows. Following requests from several customers curious about running u-center on Ubuntu, we’ve created this tutorial. Here, we will walk you through the steps to integrate precise positioning data into your Linux projects using the ArduSimple kit powered by u-blox

In our previous tutorial, we demonstrated how to connect your ArduSimple receiver to your mobile device using Bluetooth. While Bluetooth is convenient, it comes with the limitation of a short transmitting range, typically only a few meters. In this tutorial, we will guide you through the process of connecting your phone to the receiver via

In this tutorial we will guide you through the steps of connecting ArduSimple kit to TcpGPS app. This application for field work of surveyors allows the user to perform surveys, stake out plots, terrains and linear works, using base map as well as cartography and web map services. We show the steps for RTK Calibrated

Ever wondered why your GNSS receiver’s accuracy fluctuates? Proper antenna installation is key, and even small errors can greatly impact your results. Our latest YouTube tutorial is here to guide you through the optimal setup of your GNSS antenna, ensuring you achieve the best possible accuracy. From avoiding signal obstructions like buildings and trees to

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,

Post-Processed Kinematic (PPK) is a positioning technique that involves post-processing of GNSS data after the data collection is completed. PPK solutions have several advantages: No real-time corrections required: The rover hardware is simpler, less expensive, lighter, and lower power since post-processing does not require a real-time data link between base and rover.This can be advantageous

Post processed kinematic (PPK) is a GPS correction technology used in surveying that corrects the location data after it is collected and uploaded. The RINEX (Receiver Independent Exchange) format is a data exchange format for raw data from satellite positioning stations that allows the user to post-process the data received to produce a more accurate

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

If you are in the marine industry you probably have read about NMEA protocol over CAN bus, also called NMEA2000. You might have also heard that such devices are expensive, especially if you want a variant that also provides centimeter position accuracy. Today we are going to explain how to build your own NMEA2000 GPS
