In 2022, he took over the Head of R&D position, being responsible for the sensor development and calibration procedures as well as for groundstation hardware development.


Grow MultiSonde and sounding center - an introduction

A wide variety of user groups rely on multiple simultaneous radio soundings to make mission-critical decisions. Graw addresses these needs with the new scalable, modular, affordable and highly reliable MultiSonde system, which can be configured with 2-16 simultaneous receiver channels and is available in fixed and mobile configurations. The system comes with a completely redesigned GRAWMETX software that allows any number of sounding workstations to be networked to multiple receivers. Graw's sounding center resolves the well-known challenge for observation networks of managing and monitoring a large number of ground stations and remote sites. The new web-based solution is scalable and customizable and provides near-real-time quality control and visualization of sounding data. Deployments can be either cloud-based or on-premises, so data never leaves a segregated network when needed. The system can be accessed from virtually any device without additional installation, and data can be read or updated over the IP network.
