Real-time single-frequency precise point positioning for cars and trains
In this month’s Innovation column, we bring together, perhaps for the first time, single-frequency and real-time PPP. Our authors describe a series of experiments they have conducted on roadways and a railway achieving sub-meter horizontal positioning at a 95 percent confidence interval. Such accuracies may already be sufficient for freeway lane and railway track guidance. But we might expect even better accuracies in the future. After all, PPP is getting better all the time. read more

PPP for hydrography

PPP_opening_O

A new high-accuracy technique using one dual-frequency GNSS receiver, precise point positioning (PPP) offers the possibility of cost-effectively obtaining coordinates. This study investigates the accuracy of kinematic PPP for hydrographic applications on rivers, and shows results comparable to double-difference solutions. read more

Countering Ionospheric Disturbances Affecting GNSS in Brazil By Marcio Aquino After 27 months of intense research, the CALIBRA project ended successfully in February 2015, with the project team devising solutions to tackle the effects of perturbations typical of the Brazilian ionosphere on high-accuracy GNSS positioning. CALIBRA was funded by the European Union and the European GNSS Agency. Kicked off in 2012, CALIBRA first confirmed the vulnerability of... read more

UNB’s PPP Software Centre v2.0 Beta Now Available

June 17, 2015By

The PPP Software Centre, an email-based Online PPP comparison utility hosted by the University of New Brunswick, is once again functioning with its release of version 2.0 Beta following an extended hiatus while being rewritten. The centre is a convenient method for the GNSS community to compare results from several online precise point positioning services. For a more detailed description, including submission instructions, see the homepage at http://www2.unb.ca/gge/Resources/PPP/. Note that... read more
