ComNav device aids in skyscraper completion

Sep 2023 | No Comment

Sweden’s tallest building, Karlatornet, is expected to be completed in July, 2023. Karlatornet will be Gothenburg’s first skyscraper with its 246 meters. It has 74 floors and covers an area of 143,000 square meters, this inspirational new tower will mark a shift from traditional development patterns in the country.1

It is worth mentioning that 4 x SinoGNSS T300 have been used as “Active Control GNSS Points” on the building top during the construction for delivering 3D coordinates for Total Stations. One SinoGNSS T300 has been used as Base Station. The Core Wall Control Survey is a method invented by Prof. Joël van Cranenbroeck the first time for the Burj Khalifa in Dubai. The PPK mode was used to derived the most accurate results. CGEOS® Creative Geosensing Srl was the consultant for TEODOLITEN company and provided the method statement, the equipment, training and support during the construction.

GNSS-RTK technology is also used for deformation monitoring after the construction of high-rise buildings. Compared with the general buildings, the high-rise structure will produce more obvious dynamic deformation under the influence of wind load, sunshine action, seismic and other factors. Therefore, the performance and precision requirements for GNSS RTK device firmware are very demanding, and SinoGNSS T300 is more than up to the job.

The SinoGNSS T300 is a receiver entirely developed and designed by ComNav Technology, with a new RF and baseband chip built in and a unique Quantum-RTK algorithm.
