CSRS-PPP update – Automatic decimation of high-rate static submissions

Beginning Friday, March 26, 2021, the CSRS-PPP service will automatically decimate high-rate static datasets to a data rate of 30 seconds. This will affect only dual-frequency, static datasets containing both code and phase data for which at least 75% of the expected 30 second intervals are available. For all other data sets, there will be no impact. To learn more about why this change is being made, and what the impacts may be on your submission, please visit the CSRS-PPP modernization page.

CSRS-PPP service upgrade from version 2 to version 3

On Tuesday, October 20, 2020 at 11:00 EDT, the Canadian Geodetic Survey of Natural Resources Canada updated the Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP) service. This CSRS-PPP modernization includes PPP with ambiguity resolution (PPP-AR) for data collected on or after 1 January 2018. Data collected prior to this date will continue to be processed with the IGS final products without ambiguity resolution. For more information, please visit the CSRS-PPP modernization page or download the tutorial describing the changes.
