PPP
PRECISE POINT POSITIONINGSOLUTION
INTERNET BASED
WHAT IS magicPPP?magicPPP is an internet based service that permits GNSS users to determine their position or trajectory with centimeter-level accuracy.
magicPPP implements novel Precise Point Positioning (PPP) algorithms developed by GMV as a result of 25 years experience in GNSS based precise orbit determination, time synchronization and positioning.
magicPPP supports any commercial receivers that can provide data in standard formats like RINEX. Binary formats from most receivers manufacturers are also supported. Users can either upload raw data files in the web-based workspace or send them via e-mail to [email protected].
Unlike RTK, the PPP technique does not require data from core stations (CORS) in the proximity of the user. It is an ideal solution for precise trajectography over long distances and/or where no full CORS coverage is available.
MULTICONSTELLATION, MULTIFREQUENCYmagicPPP has been conceived as a multi-constellation system. It currently supports GPS and GLONASS and it is Galileo-ready. magicPPP algorithms have been thoroughly validated with real GPS and GLONASS data, as well as with data from GIOVE, the first Galileo satellite in orbit since 2008.
In order to obtain the highest accuracy level, magicPPP processes dual-frequency code and phase measurements.
CORE PRODUCTS GENERATIONPPP positioning requires a number of so-called core products that include precise orbit predictions, satellite clock corrections and other corrections for the GPS and GLONASS satellites. Precise orbits accuracy must be in the order of 2-4 centimeters and clock corrections errors must be kept around 0,15 nanoseconds.
In order to provide fast response, full autonomy and multiconstellation capabilities, magicPPP employs core products routinely generated using the company’s state-of-the-art, proprietary magicODTS precise orbit determination and time synchronization suite. The products are automatically generated processing data from a network of around 50 worldwide distributed stations.
Orbit predictions are automatically updated every 15 minutes and clock corrections can be updated up to every second and made available to magicPPP users. For the processing of GPS data, users can optionally select core products from the International GNSS Service (IGS), which are automatically managed by the system. magicPPP can also process core products generated using user-defined regional or global networks.
magicPPP can also provide real-time PPP corrections to use with standard PPP clients.
PERFORMANCEPPP positioning accuracy depends on the observation time. For observation times below 1 hour, PPP accuracy is below 10 cm. For observation times around 2 hours, PPP accuracy is around 2 cm.
magicPPP algorithms have been optimized to complete the processing and report generation in a few seconds.
EASY TO USEGNSS data processing for high precision positioning usually requires to use complex tools and a deep GNSS knowledge.
The spirit of magicPPP is to make it simpler and faster to increase productivity and speed-up the learning curve. With a few clicks, the user can upload the GNSS data, select the processing mode and obtain the precise position or trajectory. Together with the position or trajectory, magicPPP provides a complete report with comprehensive information on input data quality, configuration used, estimation process, and positioning quality.
Managing data has never been so easy, a dynamic map shows all stations and datasets available for the selected date. The user can select the datasets to process by simply clicking on the map.
magicPPP offers two preconfigured processing modes, static and kinematic. In kinematic mode, the user can select if the user is terrestrial or aerial user in order to apply the most appropriate configuration.
