Autor: Koivula Hannu, Kuokkanen Jaakko, Marila Simo, Lahtinen Sonja, Mattila Tuukka
Publikováno v: Journal of Geodetic Science, Vol 8, Iss 1, Pp 136-144 (2018)
We tested the accuracy and usability of a sparse GNSS reference station network for network RTK (NRTK) using the Finnish permanent GNSS network FinnRef. We modified the configuration of the FinnRef network stations used in NRTK computation. This allo

Datum Problem Handling in Local Tie Surveys at Wettzell and Metsähovi
Autor: Kallio, Ulla, Klügel, Thomas, Marila, Simo, Mähler, Swetlana, Poutanen, Markku, Saari, Timo, Schüler, Torben, Suurmäki, Heli
The datum problem is a fundamental issue in the network adjustment when connecting a local measurement network to an external reference frame. Datum elements in 3D networks are scale, translation, and orientation. We consider here the local tie netwo

Traditionally, sea level is observed at tide gauge stations, which usually also serve as height reference stations for national leveling networks and therefore define a height system of a country. One of the main deficiencies to use tide gauge data f
