Understanding the Geometric Dilution of Precision (GDOP) with a simple example. In A someone has measured the distance to two landmarks, and plotted their point as the intersection of two circles with the measured radius. In B the measurement has some error bounds, and their true location will lie anywhere in the green area. In C the measurement error is the same, but the error on their position has grown considerably due to the arrangement of the landmarks.
Navigation satellites with poor geometry for Geometric Dilution of Precision (GDOP). Navigation satellites with good geometry for Geometric Dilution of Precision (GDOP). Conceptually you can imagine errors on a measurement resulting in the term changing. GPS Tracking System. Tools and tips for GPS navigation and mapping. News: CGVD2013 is now available!
Natural Resources Canada has released the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the new reference standard for heights across Canada. This new height reference system is replacing the Canadian Geodetic Vertical Datum of 1928 (CGVD28), which was adopted officially by an Order in Council in 1935. Read more Geodetic reference systems stem from the need to provide a consistent and integrated reference surface for data analysis. Applications include surveying, mapping, navigation, remote sensing and mineral exploration amongst others. This site provides end-users with the geodetic data and tools they need for a range of commercial and private uses. Date modified: OpenStreetMap & Via Alpina.
