Web5 apr. 2024 · This document is a guide getting high accuracy static positions from your GPS using Precise Point Positioning [PPP]. The rare few that have a GPS that output raw measurement data for L1 and L2 can achieve absolute accuracy of around 3 cm. The u-blox ZED-F9P and ZED-F9T can be better than 1 cm. WebNatural Resources Canada (NRCan) is presently getting ready to release a new vertical datum for the country by November 2013. The Canadian Geodetic Vertical Datum of 2013 (CGVD2013) will be defined by the geopotential surface 62,636,856.0 m2s-2, which was agreed between the USA and Canada. This geopotential value is representative of the …
