适合所有GNSS参考网络
Leica Spiderqc处理GPS（包括L2C和L5），Glonass，Beidou和Galileo（包括AltBoc）数据，以所有领先的参考站软件支持标准Rinex格式。Leica SpiderQC是所有参考站网络的理想伴侣。它允许网络运营商有效地监视网络的质量。与GNSS蜘蛛参考站软件以及GR10，GR25和GMX系列接收器的卓越性能和灵活性相结合，Leica GeoSystems为GNSS参考站设定了新标准。

现场评估
Leica SpiderQC可帮助您选择参考站的最佳位置。使用它来评估代码和相多径，检查RF干扰和信号衰减，衡量数据质量和完整性等等。使用质量检查功能，以验证GNSS数据的数量（跟踪信息，数据差距），质量（周期单，多路径，SNR）和格式（符合Rinex标准）。

GNSS参考站数据的自动分析
Reference station networks generate vast amounts of data. To make a detailed analysis of this data is not possible without sophisticated analysis and reporting tools. Leica SpiderQC offers a comprehensive suite of tools tailored to the inspection, alarming, display and distribution of quality data relating to the raw data products of a reference network. Status information is available at a glance using traffic light symbols and other graphics. For more detailed investigations a range of HTML based reports, web pages and graphs can be generated.

Network RTK Performance Monitoring
The Network Online Visualisation of Accuracy (NOVA) feature of Leica SpiderQC enables you to visualize the spatial and temporal quality of single base and network RTK positioning over your network. Real time maps show the distribution of residual ionosphere and troposphere/orbit error enabling you to monitor the network status and identify problem areas in the network. The innovative NOVA maps display the estimated level of residual error for both RTK rover users receiving network corrections and single reference station (nearest site) corrections. The NOVA maps allow network operators to get a measure of the benefit that network corrections bring to their users and allow them to identify potential ‘hot spots’. Network users can view the maps over the web to get assurance on the quality of the corrections provided by the network and to decide between using nearest site and network RTK corrections for the specific location of their survey.

参考站完整性监控
Using Leica GNSS Spider Real Time Positioning or a fixed rover in your network, Leica SpiderQC can monitor the quality and availability of corrections from the network. Statistics such as accuracy, precision, availability, reliability and more can be used to quantify the integrity of the service and warn if thresholds are exceeded so corrective action can be taken.

Deformation Monitoring
Use Leica SpiderQC to detect and visualise movements of your reference stations or other critical infrastructure. Leica SpiderQC integrates with a variety of high speed real time and post processing positioning engines including Leica GNSS Spider and Bernese and any other software supporting standard NMEA and SINEX formats. The software combine to provide a flexible monitoring system for reference stations, bridges, dams, landslides and more. High precision tilt measurements from Leica Nivel 210 inclination sensors can be used to complement the GNSS derived data. Longitudinal, transverse, easting, northing, height, 2D and 3D displacements and more are computed in real time and can be displayed on screen and on the web as time series, scatter plots and vector maps. Data filtering and archiving features are also available.

Limit Checks and Messaging
Three levels of absolute limit checks for each of the longitudinal, transverse, height, 2D and 3D displacements, 2D accuracy, height accuracy, availability, x-tilt and y-tilt may be defined separately for each monitored site. A flexible messaging system allows for configuration of email, SMS and command line actions to be linked to each limit check and system message. The current connection and traffic light status of each site/sensor/solution is shown.

行业标准数据格式
Leica Spiderqc使用标准数据格式，包括Rinex（2.x，3.x），Sinex，Ionex和NMEA GGA，GNS，GGQ和LLQ，除了专有的Leica格式外。支持TCP/IP，串行和SQL数据库通信链接。Leica Spiderqc和Leica GNSS Spider和Leica SpiderWeb之间的直接链接使系统配置快速简便。
