GNSS (GPS) Data Post-Processing
Note: This information is provided as a reference and does not imply that Juniper Systems will provide full support for the use of any specific third-party device, software, or service with a Juniper Systems product.
Post-processing raw GNSS (GPS) receiver data can provide positioning accuracy improvements. The benefits of post-processing are highly dependent on the receiver hardware and field methodology. Lower cost receivers often do not support post-processing, or at least may not output the necessary information to provide any benefit after post-processing collected data. Some mid-range single frequency receivers (L1 only) can offer benefits from post-processing using software and services as listed below.

The National Geodetic Survey (NGS) OPUS service is intended for use by geomatics (certified land survey) professionals using high cost dual-frequency (L1/L2) receiver hardware. OPUS processing requires long term occupation (2 or more hours for Static, 15 minutes to 2 hours for Rapid Static) of a single position for each data point collected. A list of supported receiver hardware (antenna type) is provided on the following webpage.
