In our day-to-day RTK surveying, we usually use GSM or radio to transmit correction data from base to rover. Compared with the configuration of GSM mode, the parameters of radio mode may be more difficult to understand, such as serial port baud rate, air baud rate, radio channel, and frequency. In this blog, let’s unravel the intricacies of these concepts to empower you in achieving a seamless RTK radio mode setup.

In the field of surveying and mapping, coordinate inverse and forward calculation are very common methods, which help us determine azimuth angle, distance, point coordinates, etc. based on known information. In this blog, we will introduce these concepts and simplify their practical application with time-saving solutions of SingularPad software.

In daily RTK measurement, we usually need to input the height of the ranging pole in order to convert the coordinates into a ground target point. Have you ever wondered the original position measured by the GNSS receiver are? Is it above, below or inside the GNSS receiver?

In our previous blogs, we introduced NMEA-0183 and the key message $GPGGA. For RTK devices, providing Positioning, Navigation and Timing (PNT) data to different software and platforms often involves the use of standard NMEA messages. In this blog, we will introduce the most common NMEA messages used in RTK devices, in addition to $GPGGA.

For surveying or GIS, positioning data can meet the demands. But for some navigation applications such as auto-steering systems for agricultural operations or guiding UAVs, it is crucial to get the orientation information. We primarily describe this orientation using three parameters: pitch, heading, and roll. Roll refers to rotation around the X axis, pitch is rotation around the Y axis, and heading denotes rotation around the Z axis (as illustrated in the accompanying image).

In the last chapter, we have explored how to import a road file like XML, and how to design a road file in different methods based on your project requirements. After the preparation work, in today's blog, let's learn how to conduct the road stakeout tasks in SingularPad software with ease.
