Leica Geosystems Updates GNSS Quality Control and Data Analysis Software

August 20, 2010

Leica SpiderQC v4.0 is now part of a new reference station software update that also includes Leica GNSS Spider and Leica SpiderWeb, Leica Geosystems said. SpiderQC (previously known as GNSS QC) adds a range of advanced features for multi-frequency, multi-GNSS data analysis, visualization, and numerous other new features, improvements, and optimizations.

SpiderQC provides a suite of tools to help select the best location for reference stations, perform quality control of the reference station data, detect site movements, and visualize and monitor the integrity of single base and network RTK corrections in real time.

The new version fully supports quality control and data analysis of Galileo and GIOVE data including the E1, E5a, E5b and E5a+b (AltBOC) signals. Multi-frequency Galileo or GPS data can be used for advanced data analysis such as phase multipath estimation. With support for standard data formats including RINEX v2.11 and v3.0, Leica SpiderQC is compatible with all Leica and third-party receivers. Improved handling of GLONASS inter-frequency biases in v4.0 make analysis of data from mixed receiver types easier than before, the company said.

New features are now available for visualizing and analyzing the information recorded by Leica GNSS Spider or other reference station software when rover users connect to the system. Network operators can see who is connecting to their network and for how long, which products they are using, where they are located, and the time it takes them to obtain a RTK fixed solution.

Improved support for high-precision Leica Nivel200 inclination sensors further improves the ability to detect in real time movements of GNSS monumentation, the company said. High-precision inclination sensors can detect very small movements of the antenna independently and more accurately than the GNSS system itself. Warning messages and webpage output of status and time series now make monitoring reference stations with tilt sensors easier than before, the company said.
