Canadian Spatial Reference System and Precise Point Positioning
|GIS Learning Home|
Natural Resources Canada's (NRCAN) Canadian Geodetic Survey (CGS) provides an online application for GNSS data post-processing enabling higher accurate positioning from raw observation data. This service is unique as it allows the submission from a single frequency receiver, such as the GNSS Surveyor. In addition, processing capabilities are provided for operation in either static or kinematic modes.
Bad Elf users of the GNSS Surveyor can capture raw data and convert this raw data directly to RINEX via the tools built into the Bad Elf iOS app. Results are typically delivered in 90 minutes or less.
Before you can use this service you must create an account. To create an account at the Natural Resources of Canada, visit the following link: https://webapp.geod.nrcan.gc.ca/geod/account-compte/login.php
The steps listed below are provided as a guide for the most common of scenarios. Bad Elf suggests that you explore the NRCAN portal for a complete understanding of all the options and expectations for the results. This web link provides additional description on the service and some of the additional capabilities not outlined here.
Note: because the Bad Elf receiver does not have a registered antenna you will receive a warning that can be disregarded that states: “YourObservationFile.obs | Warning : Although an antenna record was located in the RINEX file, no phase centre information could be found in the IGS/NGS file for your antenna. Estimated height should be used with caution. Ensure that both the antenna type and the RINEX header record "ANT # / TYPE " are valid.”
