Suitable For All GNSS Reference Networks
Leica SpiderQC processes GPS (including L2C and l5), GLONASS and Galileo (including AltBOC) data in the standard RINEX format that is supported by all leading reference station software. Leica SpiderQC is the perfect companion for all reference station networks. It allows the network operator to monitor the quality of the network in an efficient manner. Paired with the superior performance and flexibility of GNSS Spider reference station software and the GR10, GRX1200+ and GMX902 receivers, Leica Geosystems is setting new standards for GNSS Reference Stations.

		Leica SpiderQC helps you to select the best location for your reference station. Use it to evaluate code and phase multipath, check for RF interference and signal attenuation, measure data quality and completeness and much more. Use the Quality Check feature for verification of the quantity (tracking information, data gaps), quality (cycle slips, multipath, SNR) and the format (compliance to the RINEX standard) of your GNSS data.

		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.

		Using Leica GNSS Spider RT 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.

		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 Nivel200 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.
