InteTrak GPS Network Monitoring Software

The InteTrak GPS Network Monitoring Software comprehensively manages the collection, processing and tracking of data from continuous and semi-permanent GPS networks deployed for high precision displacement monitoring of structures and natural hazards.

InteTrak manages:

• GPS field station operations and network communications, including remote GPS receiver configuration.
• Real-time GPS data streaming via network and serial protocols.
• Sub-centimeter, near-real-time static and kinematic* GPS processing.
• Full integration with the embedded database server.
• Database and disk file archival of raw GPS code and carrier phase measurement data, satellite ephemerides, and kinematic and static processing results.
• Time series, 2-D graphics of positioning data (North, East and Vertical [NEU]) data tables, message logs.
• Graphical interface for manual cleaning of data outliers.
• Automated programmatic cleaning of outliers using statistical data filters.
• Solutions (positions, processing and statistics) data export and reports.

InteTrak was developed for unattended and autonomous network operation to generate continuous, high-rate displacement and deformation monitoring for scientists, engineers and operations managers. It has been adapted and applied to automated, periodic campaign surveys for repeat, campaign monitoring of large infrastructure.

Notes:
* Software releases from 2002-2006 consisted of static (RS), kinematic (RT) and the combined static and kinematic (CMB) processing packages. The kinematic engine was developed primarily for high-rate monitoring of tall buildings and long-span bridges. However, it was also used for processing L1-only data in CMB-mode for slope stability monitoring projects. L1-kinematic processing is a rarely used approach (kinematic is more reliable on dual frequency [L1/L2] GPS data). Although it did show monitoring utility and could be beneficial for recording failure mechanisms, the high-rate data burden associated with kinematic was determined to be of limited benefit in slope stability monitoring. Therefore, the kinematic module was sidelined during a major rewrite. However, we are developing new approaches to high-rate positioning and reintegration of kinematic processing into InteTrak.
