Technologies

Geodetics' technologies provide three-dimensional Precise Instantaneous GPS ("ΠGPS") positioning for applications ranging from positioning a single static/dynamic object, to monitoring many static, deforming and dynamic objects in a wide-area network simultaneously.  The technologies can also provide very accurate attitude information for dynamic objects.

The technologies are based on Geodetics' proprietary RNA (Rapid Network Analysis) module with Epoch-by-Epoch™ technology, a new class of instantaneous, real-time GPS positioning algorithms.

This innovative technology provides an independent estimate of position for each epoch of dual-frequency (L1 and L2) observations to five or more GPS satellites.  Geodetics products also supports geodetic-quality single-frequency (L1) observations for localized networks.

Epoch-by-Epoch™ Advantages

• Provides instantaneous initialization and re-initialization compared to the typical 30-45 seconds for RTK positioning
• Unaffected by cycle slips and receiver losses of lock
• Easier to detect and reject bad data points compared to batch or RTK positioning methods
• Robust estimation of multiple single-epoch static positions improves site coordinate precision vs conventional batch processing
• Extremely efficient algorithms allow the simultaneous, real-time network positioning of multiple (> 50) receivers sampling at high receiver sampling rates

Geodetics' Real Time Dynamic (RTD) family of products, based on Epoch-by-Epoch™ technology, controls completely the flow of data from networks ranging from two to hundreds of GPS instruments into multiple data servers, data archives, and clients (rovers).

RTD's server/client applications support Precise Instantaneous Network ("PIN") positioning, while simultaneously monitoring the integrity and possible deformation of the base network, Epoch-by-Epoch™.

PIN positioning is a new network-based real-time methodology, not requiring multi-epoch initialization and re-initialization inherent in conventional RTK surveying and network RTK methods.  Geodetics technologies have been especially designed for real-time, wireless environments, and the software is optimized for extremely fast dissemination and processing of data.
