PPP as an alternative procurement method for corporates

22nd Annual European Real Estate Society Conference, 2015
Real estate, mainly being workspace, is an important resource for non-property companies and their core business processes, and ultimately influences productivity. Procurement of such real estate as well as servicing and maintaining it, incurs extensive capital and operating costs, which in turn have a significant impact on the company's performance ...

PPP Performance with Large TEC Gradient and Mitigation Methods

2020 European Navigation Conference (ENC), 2020
During high-level solar activity time, frequent ionospheric irregularities lead to large total electron content (TEC) gradient. precise point positioning (PPP) performance can be significantly degraded under the unfavorable ionosphere conditions. We analyze the causes and effects of the ionosphere potential impacts on uncombined PPP (UPPP) performance ...

A new method to avoid PPP in data evaluation

Chinese Physics, 2004
The Peelle Pertinent Puzzle (PPP) has been studied systematically. The results obtained by using several proposed methods to deal with a sample of 6Li(n,t) are compared with each other. The cause of PPP occurrence has been found. A new method to avoid PPP is introduced, whose main idea is `to selectively make suitable correction for systematic error ...

A comparison of three PPP integer ambiguity resolution methods

GPS Solutions, 2013
Precise point positioning (PPP) integer ambiguity resolution with a single receiver can be achieved using advanced satellite augmentation corrections. Several PPP integer ambiguity resolution methods have been developed, which include the decoupled clock model, the single-difference between-satellites model, and the integer phase clock model.
