Spot 卫星的组装和试验正在按计划进行。卫星将于1985年底发射。有效载荷试验已于1984年12月底结束,在此之前在图卢兹空间中心的环境模拟台上进行了太阳真空和热真空试验。平台的组装及试验与有效载荷试验同时进行。平台已于1985年初交货。平台及有效载荷的组装是1985年1月初完成的,之后进行了校准测量、电试验和卫星性能试验。 Spot satellites are being assembled and tested as planned. The satellite will be launched by the end of 1985. The payload test, which ended in late December 1984, was followed by solar vacuum and thermal vacuum tests at an environmental simulation station at the Toulouse Space Center. Platform assembly and testing are carried out simultaneously with the payload test. The platform was delivered in early 1985. The assembly of the platform and payload was completed in early January 1985, followed by calibration measurements, electrical tests and satellite performance tests.
