GNSShöjdmätare
GNSShöjdmätare is a compact, modular sensing system designed to measure vertical displacement and height-related phenomena in geophysical and engineering contexts. The device combines optical interferometry, inertial sensing, and GNSS positioning to provide high-resolution measurements of altitude changes and related parameters. It is intended for use on fixed installations, mobile platforms such as unmanned aerial systems, and handheld survey setups.
The core of GNSShöjdmätare is an optical interferometer that monitors phase changes in a short, stabilized
Applications span geodesy, earthquake and structural monitoring, volcano and atmospheric research, and civil engineering. In field
Development of the instrument began in the mid-2010s, with iterative prototypes progressing toward sensitive, field-ready configurations
