Perhaps you’ll spare me the time to tell you a personal story about Harxon. I use one of their antennas (specifically the HX-GS481A) on one of our GNSS RTK base stations. At one point the antenna quit working: I’m inclined to believe it was a lightning strike because we get a l...
1x 20+ft SMA extension can be handy when first experimenting with base stations so you can sit indoors with a laptop and analyze the output of the GPS-RTK 1x A standard camera tripod The ZED-F9P can be configured using Serial, SPI, or I2C. We’re fans of the daisy chain-ability of...
Fixed coordinates were obtained using long-static averaging with a tripod (~240 min), over several periods of time, and postprocessed in comparison with nearby IGN (Institut Géographique National) GNSS stations. Repeated measurements of other geodetic marks provide insights on georeferencing quality. ...
Figure 1. Distribution map of the experimental stations. 2.2. NWP ZTD Integral Method Two methods: the integral method and model estimation method, are commonly used to derive the ZTD from the NWP meteorological parameters [28]. In this study, the results of the integral method and model ...
For effective GNSS-RTK processing, it is essential to have reference stations with accurately known locations as a prerequisite. The single difference (SD) measurement equations for the rover and reference receivers [34] can be expressed as Psf ,br = ρsbr + c dtbr − dtsf ,br + Isbr ...
