Accuracy of GPS precise point positioning (PPP)

, 2020
We tried to show how the accuracy of GPS varies with respect to observing sessionduration by using the method of GIPSY precise point positioning (PPP), and how the site?scoordinates latitude, longitude and ellipsoidal height are affected.We used eleven IGS sites scattered almost evenly across the earth. GPS data wereobtained from SOPAC archives at http:

Shaping Energy Transitions: Sectoral Demand, Climate Risk Exposure, and Renewable Pathways in Sub‐Saharan Africa

Business Strategy and the Environment, EarlyView.
ABSTRACT Energy is a fundamental driver of economic growth, shaping productivity, industrialization, and long‐term economic resilience. In sub‐Saharan Africa (SSA), where energy access remains uneven and infrastructure is underdeveloped, understanding sector‐specific energy demand is essential for designing sustainable energy strategies.

Does Climate Risk Affect Employment Decisions? International Evidence

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the effect of climate risk on corporate employment decisions. Using a large sample from 41 countries, we find a positive association between climate risk and underinvestment in labor, notably manifesting as excessive employee layoffs.

Market and Nonmarket Strategies in Focus: How Entrepreneurs Tackling the Grand Challenge of Waste Management Navigate Institutional and Market Adversity in Ghana

Business Strategy and the Environment, EarlyView.
ABSTRACT Waste management remains a critical grand challenge in African countries. While entrepreneurship has been a viable strategy for addressing this challenge, it is fraught with constraints. This study investigates the strategies orchestrated by entrepreneurs to navigate adversity in Waste management and ensure the social and economic viability of

Board Networks and Corporate Carbon Emissions: A Cross‐Country Analysis of Causal Effects

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether board networks influence corporate carbon emissions and the strategic pathways through which firms decarbonize. Using a sample of 1952 firms across 48 countries from 2003 to 2020, we employ dynamic stacked regressions that exploit exogenous carbon‐regulation shocks affecting firms connected through shared third ...

Realtidsmätning inom fastighetsbildning med "Precise Point Positioning" (PPP)

, 2016
Vid GNSS-positionering i samband med fastighetsbildningsåtgärder används vanligtvis den traditionella RTK-mätningen (Real-Time Kinematic) via SWEPOS nätverks-RTK-tjänst. Denna tjänst kräver mobiltelefontäckning eller motsvarande tvåvägskommunikation, vilket kan vara problematiskt inom områden med bristfällig mobiltelefontäckning.

Consolidation and assessment of a technique to provide fast and precise point positioning (Fast-PPP)

, 2023
The research of this paper-based dissertation is focused on the Fast Precise Point Positioning (Fast-PPP) technique. The novelty relies on using an accurate ionosphere model, in combination with the standard precise satellite clock and orbit products, to reduce the convergence time of state-of-the-art high-accuracy navigation techniques from ...
