Veripos extends Apex service, offers Quantum software

Veripos, a global supplier of high-precision GNSS positioning services to the offshore oil and gas industries, has extended its ranges of proprietary software with the introduction of Quantum, a new, all-purpose suite of visualization modules providing a state-of-the-art user interface to support next-generation services and features.

Designed to operate with all current Veripos positioning options including its latest Apex5 multi-constellation PPP service (see below), the new software has been developed with significant input from a wide range of users by way of simplifying any system configuration while easing methods of interpretation. Other advances include integral diagnostic functions for simple identification of operational problems together with indications of likely solutions.

Visualization modules can also be operated independently without affecting concurrent positioning calculations which might otherwise be feeding critical survey or vessel systems.

At the same time, the Quantum framework comprises a series of different modules to meet a variety of specific operational tasks such as those necessary for hydrographic and seismic surveying as well as dynamic positioning. Its versatility also extends to providing a basic foundation for accommodating new modules or features.

Apex5 PPP service launched

Veripos has extended its Apex service with introduction of Apex5, which is capable of receiving observations from five available satellite constellations comprising GPS, GLONASS, Beidou, Galileo and QZSS.

Using precise point positioning (PPP) methods for correction or modeling of all GNSS error sources, the new multi-constellation service with its access to increased civilian signals ensures greater power levels via interoperable networks in addition to improved levels of observation and redundancy.  Other advantages include a higher satellite count and position availability, particularly in masked and scintillated environments.

Calculations are based on Veripos’s own orbit and clock determination system (OCDS) which derives real-time corrections for all available satellite constellations using proprietary algorithms.  The OCDS uses data from the company’s own global network of reference stations with multiple and redundant systems supported by dedicated network control centres in Aberdeen and Singapore.

Apex5 is broadcast alongside existing Apex, Apex2 and Ultra services via seven geostationary satellites to ensure continuous availability and service redundancy. Typical position accuracies are better than 5cm horizontal at the two sigma (95 percent) confidence level.
