SRAL
Definition
- The SRAL instrument comprises one nadir-looking antenna, externally mounted on the satellite's +Zs Earth panel, and a central electronic chain composed of a Digital Processing Unit (DPU) and a Radio Frequency Unit (RFU). The central electronic chain is mounted inside the satellite on the -Ys panel in a cold redundant configuration. The main frequency used for range measurements is the Ku-band (13.575 GHz, bandwidth 350 MHz), while the C-band frequency (5.41 GHz, bandwidth 320 MHz) is used for ionospheric correction. (en)
