ERBS

 1984-108B


The Earth Radiation Budget Satellite (ERBS) was originally planned as the fourth Applications Explorer Mission (AEM-D). ERBS was carried into space aboard the Space Shuttle Challenger on mission 41-G. Launch was at 1103 on 1984 Oct 5. It was deployed by the RMS arm at 2218 on Oct 5 into a 353 x 355 km x 57 deg orbit. A hydrazine internal propulsion system was used to raise the orbit. Its final orbit was 601 x 605 km x 57 deg.

DFH-46

 1999-025A


The first operational FY-1, FY-1C, was launched in 1999. The number of channels in the radiometer was increased, as well as on board data storage capacity. The resolution is 1.1 km. Vehicle is a 1.4m cube with two solar panels of 8.6m span. Mass is 958 kg. According to AvWeek, FY-1C was built by CAST/Beijing for the National Satellite Meteorological Center  but most sources say the FY-1 series were built in Shanghai.
