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

In the previous tutorial on configuring the simpleRTK3B as a static base station, we demonstrated the process of establishing the reference position using Septentrio’s auto mode. While this method provides a fundamental reference with good pass-to-pass accuracy, achieving high absolute accuracy for the rover requires the utilization of an exceptionally precise reference position. There are

QField is a mobile field mapping and data collection app that integrates with QGIS, allowing for efficient outdoor data gathering directly compatible with QGIS desktop. QField can run on Android, iOS, Windows, Linux and MacOS. If you want to know how to use RTK receiver with QField on your Android device instead of iOS, check

Onocoy is a community-powered GNSS reference station network that provides high-quality RTK reference station data to enable ultra-precise positioning. It ensures a high data quality through rigorous data validation and by incentivizing operators of reference stations with rewards. At the core of getting rewards for contributing your RTK reference station data to Onocoy lies the

QGIS is a free and open-source desktop geographic information system (GIS) app that provides data viewing, editing, and analysis. It can be used for almost any GIS application by GIS analysts, cartographers, surveyors, foresters etc. to visualize geographic information. In this tutorial, we’ll explain step by step how to integrate your RTK receiver with QGIS,
