There are two main ways to obtain high-confidence coordinates for a GNSS base station: Process data from the site relative to other high-confidence static sites, or submit site data to an online point positioning service. If your new base site is within 50 km of a reference site and you have collected several hours of data, it is best to process the site data yourself using e.g. Trimble Geomatics Office (see How to process fast-static and post-processing kinematic surveys using TGO). Otherwise, to obtain a position to within several cm of a static point where a very accurate position is not needed, submit site data to one of the following online services.
CSRS PPP (Canadian Spatial Reference System - Precise Point Positioning) is a flexible service which offers both static and kinematic data processing. Access to the database is free but requires a username and password. Data files can be uploaded directly to the site.
A data file of at least two hours is recommended. Data files can be uploaded directly to the site.
Data files can be uploaded directly to the site.
A JPL service that replaces AutoGIPSY. Data files can be uploaded directly to the site.
