“…The altimeter electronics is configured in four boxes, two processing units, and two radio-frequency units (nominal and back-up). POS-3 has improved functionality compared to POS-2 on Jason-1 (Carayon et al 2003), such as configuration modes, use of a digital elevation model, and a tracking mode over inland waters or land and coastal areas (see Desjonqueres et al 2009, later in this same issue). The DORIS Precise Orbit Determination system, also a core instrument, provided by CNES (Figures 4 and 5) whose performance has been demonstrated on T/P and Jason-1.…”

Jason-2 was successfully launched by a Boeing Delta II rocket from the Vandenberg site, California. The OSTM/Jason-2 project is a cooperation among NASA, NOAA, EUMETSAT, and CNES. The first two months of the OSTM/Jason-2 mission have been dedicated to the assessment of the overall system. The goal of this assessment phase was:(i) to assess the behavior of the spacecraft, at the platform and payload levels; (ii) to verify that platform performance requirements are met with respect to Jason-2 requirements; (iii) to verify that payload instruments performance requirements evaluated at instrument level are met; and (iv) to assess the performance of the Jason-2 Ground System. The paper will display the main outputs of the assessment of the system. It will demonstrate that all the elements of the onboard and ground systems are within the specifications.

“…In this respect, Steunou et al (2002) and Carayon et al (2003) have performed an extensive analysis of the Jason-1 altimeter noise from the instrument point of view. In parallel, using a high pass filtering technique applied to 20 Hz high rate and the usual 1 Hz compressed measurements, Vincent et al (2003a) described by Dorandeu et al (2002b).…”

One year of collocated, rain-free nadir Ku-band backscatter cross-section measurements from the Tropical Rainfall Mapping Mission (TRMM) precipitation radar (PR) and both Jason-1 and Envisat RA-2 altimeter measurements have been compiled to compare these three sources of Ku-band radar cross section. With the exception of a ϩ1.46 dB relative offset between Jason-1 and PR measurements and a Ϫ1.40 dB offset between Envisat and PR ones, all three Ku-band measurements compare very well in terms of dependencies upon model wind speed estimates and significant wave height measurements. The altimeter radars and the rain radar thus provide consistent measurements, and observed biases can be rationalized as differences in the radar calibration. The precipitation radar, which also covers off-nadir measurements, has been absolutely calibrated using an active radar calibrator. Consequently, the observed relative offsets can be used to indirectly calibrate both Jason-1 and Envisat altimeter Ku-band radar cross sections in an absolute sense.
