Abstract
Conventional radar and laser altimeters offer high altimetric accuracy but with insufficient spatial and temporal resolution. Global Navigation Satellite System-Reflectometry (GNSS-R) reveals new perspectives for Earth observations. Earthreflected signals from GNSS systems show high reflection characteristics to some surfaces like water, ice and wet soil. The main advantage of GNSS-R is the large number of available GNSS signals and their dense global coverage so that multiple simultaneous height measurements within a wide field of view are possible. The subject of the following paper is to introduce GNSS-R and to summarize some of the activities done at GFZ. In addition, preliminary results from ongoing work will be presented.
