Waypoint RTKNav/RtStatic

Real-Time

The RTKNav/RtStatic/RtDLL series of modules form the basis of our Win2000/XP (not recommended for Windows 98 or NT 4.0) based Real-Time-Kinematic applications. They are designed for accuracies from the centimetre to sub-metre level. The real-time modules have a specific graphical interface like GrafNav/GrafNet, but they are principally designed so that developers can integrate these modules into their own systems. One feature of the modules is that they have the ability to process data simultaneously from up to 20 remote GPS receivers. Also, the modules can perform high precision computations whether the base station is stationary or moving. This provides additional flexibility for users who require relative range and azimuth determination from a moving base to a non-stationary target. These modules can also be configured in an attitude determination mode for computation of roll, pitch and azimuth.

RTKNav is a stand-alone RTK program with a full-featured Graphical Interface capable of handling code and carrier phase data from up to 20 remotes simultaneously while providing up to centimetric accuracies from single or dual frequency receivers. This module has its own built-in serial and network device driver, and it can handle real-time binary data from Ashtech, Marconi, NovAtel, and NavSymm receivers simultaneously on any combination of serial or network ports. Processed and/or raw data may also be written to the hard disk or output from a separate serial or network port to another device or computer.

The report Tracking Sonobuoy's with RTKNav (PDF - 112KB) describes how RTKNav was used to process data from GPS-equipped sonobuoys in the calibration of underwater sonar systems.

RtStatic is an optional add-on to the RTKNav real-time kinematic processing package. This option is aimed at near real-time deformation monitoring applications. RtStatic uses Waypoint's GrafNav processing engine to provide Fixed Static solutions in near real-time. Simultaneously, the standard kinematic engine processes the same data in real-time to monitor fast moving events in standard kinematic fashion. Filtering of the time history of the Fixed Static solutions produces millimetre level coordinate changes on slow-moving features such as slopes or dams. On short baselines, single or dual frequency receivers can be used with similar precision. Raw input or processed output data can be transferred in real-time over serial or network connections.
