|Abstract:||This work addresses the topic of using low cost GNSS sensors for infrastructure and land monitoring with the aim of presenting the technological solution proposed by Nottingham Scientific Limited (NSL) and currently adopted in the frame of “LiveLand” Demonstration Project, within the ESA integrated Applications Promotion Programme. The first network of NSL’s low cost devices (named “STICK”) will be deployed around the West Highland Line railway track at Glen Douglas (about 47Km NW of Glasgow, Scotland). Several problems will affect the installation of the low cost GNSS monitoring network which is meant to be continuously operating in a site where the communication coverage is poor, the availability of the main power distribution is lacking and continuous operating GNSS reference stations are not nearby. Here we describe how such limitations are going to be overcome and how the STICK architecture works: the network is composed by different nodes which transmit raw data acquired by the STICK units to the NSL server. Different communication options are available for ensuring direct contact during operation. The server receives and stores the transmitted data and the serverbased positioning software automatically processes the raw data by providing estimated position and displacements information. The performances of the GNSS sensor and the software adopted by the NSL’s processing engine in its current state of art are presented through multiple tests. Dynamic and pseudo-static tests were carried out for assessing the achievable accuracy and precision, problems, optimal configurations and operations.|
