Parsons will send a Level 0 data file to ESPC on May 1 for product processing. The file is expected to carry a two-orbit long GAC data, covering the observation time from 13:26:43z to 17:01:33z. The file will be used to test the relevant L1a and L1b product processing at NSOF. The possible outcomes include:

·      Two separate L1b GAC files, each of which is one orbit long;

·      One L1b GAC files, which is two orbits long, or
