Precise Positioning Now for Everyone

In the relentless drive for greater accuracy, faster convergence and globally available positioning, the recent technological breakthrough of RTK From the Sky has excited comment. This will enable instantaneous centimeter-level accuracy for land, air and marine applications around the world, according to Hexagon. The new approach effectively provides users with the complementary benefits of real-time kinematic (RTK) and precise point positioning (PPP): rapid accuracy everywhere, without dependency on local base stations.

Three expert speakers explore the relative aspects and benefits that commercial and publicly available multi-GNSS corrections now afford. Based on the requirements from corrections customers — accuracy, availability, continuity and rapid convergence — they’ll discuss how these PPP correction services work: real-time transmission, raw data, corrections processing, data set transmission and the benefits of global centimeter-level accuracy across user applications.

These experts discuss how RTK From the Sky technology will be incorporated into the TerraStar portfolio, the new Galileo High Accuracy Service (HAS), transmitting PPP corrections over the E6-B signal, and the multi-GNSS Real-Time Service (RTS) of the International GNSS Service (IGS).
