Recent activity of international standardization for highaccuracy GNSS correction service
Dr Rui Hirokawa
In this article, the recent activities of international standardization for high- accuracy GNSS correction services are introduced. The high-accuracy GNSS positioning will be widely accepted in a wide range of applications for next decade, the inter-operability of different services and receivers is highly important.... [more]

Remote Sensing for air pollution control
A K Jain
Air pollution in India has become one of the most serious causes of environmental damage and health risks. As per the WHO (2018), 13 Indian cities are among the World's top 20 cities with severe levels of PM 2.5 and PM10. The strategic pathway towards clean air starts with digital, real time development of various sources of air pollution. This should be the basis of the preparation of pollution control plans at district, municipal, and local levels.... [more]

Global experiences with public private partnerships for land registry services: A critical review
Dr. Keith Clifford Bell
The purpose of this paper is to provide an overview of experiences globally with LRS PPPs and privatization proposals. We present here the first of the three parts of the paper.... [more]

The general advantages of multi-GNSS are that one can obtain more accurate and more robust parameter solutions.
In the positioning domain this translates into faster executions of PPP and PPP-RTK due to the shorter convergence times and for RTK to the ability of using longer baseline lengths for which instantaneous ambiguity resolution is still possible....says Professor Peter Teunissen
