ESA-OSIP Alticube+ project in its final stage!

In autumn 2023 the ESA OSIP project “Alticube+ – An Aggregated CubeSats Swarm for Long Fixed-baseline Radar Altimetry” started as one of the seven studies selected from around 70 proposals. OSIP stands for Open Space Innovation Platform. This program offers the exploration of new ideas and may lead to activities …

A successful Radar Altimetry shortcourse

Peter Hoogeboom, emeritus professor Radar Remote Sensing of TU Delft gave a shortcourse on radar altimetry to those who were interested and involved in NL-RIA’s activities to realize a constellation of cubesat-based radar altimeters. The course started off with the properties and operating principles of altimeters and gradually deepened into …

KNMI is 18th member of NL-RIA

On 23 November 2022 KNMI joined the NL-RIA knowledge network. Contact person is Ad Stoffelen. Together with colleagues he performs scientific research on the use and performance of spaceborne radar instruments, including windscatterometers and altimeters. KNMI’s membership brings in expertise in this field, which strengthens the user side of NL-RIA. …

New milestone in radar altimeter electronics development

Recently NL-RIA’s partner RFx solutions managed to realize the first radarboard for the 35 GHz miniaturized altimeter. The design is based on work from Ozan Doğan, during his post-doc assignment. The development was sincerely delayed by Covid-19 and by the worldwide shortages in chips. But after a long period of …
