Triple frequency or dual frequency?
2024.05.16
With the development of global satellite navigation systems, RTK technology has also gradually evolved and improved. In this process, multiple satellite navigation systems such as GPS, GLONASS, Galileo, and BeiDou have successively introduced multi-frequency signals, providing possibilities for achieving higher positioning accuracy.
Galileo High Accuracy Service (HAS) Performance Analysis Report
2024.04.29
Precise Point Positioning (PPP) technology can achieve high-precision positioning anywhere in the world. Compared with real-time dynamic differential positioning technology, PPP technology does not require a dense reference station network, but its accuracy relies on high-precision satellite orbits and clock deviation products. The Galileo satellite navigation system is a global navigation satellite system (GNSS) jointly developed by the European Union (EU) and the European Space Agency (ESA). Among them, the High Accuracy Service (HAS) issued by the Galileo satellite navigation system can provide real-time precision single point positioning (PPP) services worldwide. Since the birth of the Galileo satellite navigation system, many domestic and foreign scholars and experts have conducted a large amount of research on satellite signal modes, satellite data quality, navigation algorithms, positioning performance evaluation and other aspects based on simulated data or measured data.

The High Precision GIS Pocket Tablet P6H combines the convenience of a handheld device with cutting-edge GNSS technology, making it a game-changer for GIS specialists and investors alike. This article explores the remarkable features and potential impact of ComNav's P6H on the GIS sector.
Alert on Strong Geomagnetic Storming and How Lonospheric Activity Impact on GNSS Performance
2024.03.25
The 23 March CME arrived at around 24/1411 UTC. Severe (G4) geomagnetic storming has been observed and is expected to continue through the remainder of the 24 March-UTC day and into the first half of 25 March. The alert issued by NOAA's Space Weather Prediction Center in Boulder, Colorado.
Galileo's High Accuracy Service (HAS): Unlocking the Potential of Positioning, Navigation, and Timing (PNT) in Africa and Lessons for Global Constellations
2024.03.21
Galileo, Europe's Global Navigation Satellite System, introduced the High Accuracy Service (HAS) to enhance positioning precision. The implementation of HAS in Africa holds substantial promise for revolutionizing Positioning, Navigation, and Timing (PNT) services across the continent. This article examines the transformative impact of Galileo's HAS in Africa and explores the valuable insights that other GNSS constellations can glean from its successful application.
Logging Raw Observation Data for GNSS Devices
2024.03.12
This blog delineates the meticulous process of logging raw observation data from your GNSS device. This data serves a dual purpose: primarily, it is indispensable for post-processing analysis, and secondarily, it furnishes valuable debug information for troubleshooting anomalies. We'll delve into both aspects comprehensively.
Precision Meets Efficiency: The LS300 Laser Scanner Delivers Rapid and High-Quality Data in Rigorous Test
2024.02.20
In an impressive display of technological prowess, ComNav Technology Ltd. has completed a challenging scanning demonstration with the LS300 Laser Scanner. This test highlighted not just the speed of the LS300, but also the exceptional quality of data it can collect, setting a new benchmark in precision scanning solutions.
How to active PPP option for GNSS modules/receivers in your hand
2024.01.30
ComNav's K8 series modules have been fully upgraded. The latest 620F1 official firmware version can support both PPP and RTK. It can support PPP-B2b and PPP-HAS without customization, which to a large extent solves the problem of low accuracy requirements. This advancement is particularly advantageous for customers operating without base stations, eliminating potential complications.So what are the convergence criteria for PPP? How accurate is it?
