2. Precise Point Positioning - Wikipedia

   en.wikipedia.org/wiki/Precise_Point_Positioning

   Precise positioning is increasingly used in the fields including robotics, autonomous navigation, agriculture, construction, and mining. [2]The major weaknesses of PPP, compared with conventional consumer GNSS methods, are that it takes more processing power, it requires an outside ephemeris correction stream, and it takes some time (up to tens of minutes) to converge to full accuracy.

3. Satellite navigation - Wikipedia

   en.wikipedia.org/wiki/Satellite_navigation

   GNSS-2 is the second generation of systems that independently provide a full civilian satellite navigation system, exemplified by the European Galileo positioning system. [5] These systems will provide the accuracy and integrity monitoring necessary for civil navigation; including aircraft.

4. Southern Positioning Augmentation Network - Wikipedia

   en.wikipedia.org/wiki/Southern_Positioning...

   Precise Point Positioning (PPP) via SouthPAN (PVS) service will provide horizontal accuracies of 15cm (95% Confidence) to a range of industries following a convergence time in the tens of minutes. The PVS service will be open access and able to be incorporated onto mass-market GNSS devices across Australia, New Zealand and their maritime zones.

5. GNSS enhancement - Wikipedia

   en.wikipedia.org/wiki/GNSS_enhancement

   GNSS enhancement refers to techniques used to improve the accuracy of positioning information provided by the Global Positioning System or other global navigation satellite systems in general, a network of satellites used for navigation. Enhancement methods of improving accuracy rely on external information being integrated into the calculation ...

6. Real-time kinematic positioning - Wikipedia

   en.wikipedia.org/.../Real-time_kinematic_positioning

   A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1]

7. GNSS applications - Wikipedia

   en.wikipedia.org/wiki/GNSS_applications

   Spacecraft use GNSS as a navigational tool. The addition of a GNSS receiver to a spacecraft allows precise orbit determination without a ground tracking station. This, in turn, enables autonomous spacecraft navigation, formation flying, and autonomous rendezvous. The use of GNSS in MEO, GEO, HEO, and highly elliptical orbits is feasible only if ...
