Septentrio Post-Processing Kinematic (PPK) software has been upgraded with multi-GNSS and BaseFinder functionality. BaseFinder improves project efficiency by automatically finding the most suitable reference station data needed for centimeter-level accuracy.
–Septentrio, a leading
manufacturer of accurate and reliable GPS technology, has released a key
upgrade for their GPS post-processing software. Both GeoTagZ and PP-SDK now feature
BaseFinder, a tool that speeds up survey workflow by automatically finding
reference data needed for augmenting GNSS* logs with sub-centimeter accuracy.
BaseFinder accesses an online database of reference networks and extracts the
most suitable corrections available. BaseFinder is available via an App or via
an API and can be incorporated into any existing software.
*GNSS: Global Navigation Satellite System such as the American
GPS, European Galileo, Russian GLONASS, and Chinese BeiDou. These satellite
constellations broadcast positioning information to receivers which use it to
calculate their absolute position.
Septentrio has two decades of experience delivering reliable and
robust RTK and PPK sub-centimeter positioning to industrial applications. PPK
is often used for ground surveys with aerial drones, allowing high precision
georeferencing without the need for a real-time base station link or ground
control points (GCPs).
“Surveying without a base station will allow users to reduce
costs and set-up time. With this PPK upgrade we are improving the end-user
experience as well as developer experience,” commented Danilo Sabbatini,
Product Manager at Septentrio.
The new release of this GNSS post-processing software also
includes two additional GNSS constellations: European Galileo and Chinese
BeiDou. Having access to all the signals from all GNSS constellations improves
reference network compatibility. It also improves positioning availability in
difficult environments. This is particularly important when working in areas of
low satellite visibility such as near tall structures or under foliage.
When doing photogrammetry with a drone, GNSS data is often recorded and then post-processed together with base station data to achieve sub-centimeter positioning accuracy. This base station data can be obtained either with proprietary base stations or by using base station data from a public reference network (see diagram below). Septentrio receivers are designed to bring accurate and reliable positioning to photogrammetry, aerial inspection, marine survey as well as mobile mapping.
