The NAVY GFO satellite was launched on February 10, 1998. The spacecraft system and the GPS instrument have experienced a number of problems that have prevented the mission from entering normal operations. However the GFO radar altimeter has been turned on a number of times and does appear to be performing well. We have been approved to help monitor the long term trends in the altimeter similar to the functions we have been performing for the Ocean Topography Experiment POSEIDON (TOPEX) radar altimeter. We will present some analysis of the pre-launch test data from the GFO altimeter to indicate the characteristics of the instrument. We will also present analysis of in-flight data indicating that the altimeter performance appears to be nominal. The current in-flight trends based on the calibration mode will be discussed.
