A PPP-RTK APPROACH TO MASS-MARKET APPLICATIONS

A Novel Un-differenced PPP-RTK Concept

In this contribution, a novel un-differenced (UD) (PPP-RTK) concept, i.e. a synthesis of Precise Point Positioning and Network-based Real-Time Kinematic concept, is introduced. In the first step of our PPP-RTK approach, the UD GNSS observations from a regional reference network are processed based upon re-parameterised observation equations, corrections for satellite clocks, phase biases and (i...

Review and principles of PPP-RTK methods

PPP-RTK is integer ambiguity resolutionenabled precise point positioning. In this contribution, we present the principles of PPP-RTK, together with a review of different mechanizations that have been proposed in the literature. By application of S-system theory, the estimable parameters of the different methods are identified and compared. Their interpretation is essential for gaining a proper ...

PPP-RTK: Results of CORS Network-Based PPP with Integer Ambiguity Resolution

During the last decade the technique of CORS-based Network RTK has been proven capable of providing cm-level positioning accuracy for rovers receiving GNSS correction data from the CORS network. The technique relies on successful integer carrier-phase ambiguity resolution at both network and user level: at the level of the CORS network, ambiguity resolution is a prerequisite in order to determi...

Pricing-to-Market and the Failure of Absolute PPP

We show that deviations from the law of one price in tradable goods are an important source of violations of absolute PPP across countries. Using highly disaggregated export data, we document systematic international price discrimination: at the U.S. dock, U.S. exporters ship the same good to low-income countries at lower prices. This pricing-to-market is about twice as important as any local n...
