AB: Precision satellite orbit determination, constellation station-keeping, debris avoidance, reentry timing, satellite subsystem performance and safety, and communication link enhancement are among the major technological activities that are affected by space weather. There are numerous applications being developed to mitigate space weather affects on these domains. However, the common language for information exchange still needs community attention. We report on progress towards a) providing applications and services that mitigate adverse effects caused by space weather and b) developing international standards for exchange of information. For applications and services, Space Environment Technologies (SET) has developed a) new solar indices that reduce 1-sigma uncertainty by 50 percent in atmosphere density calculations, b) new spacecraft surface charging characterizations, and c) new solar irradiances that capture solar flare effects on transionospheric communications. These solar products have been developed and tested for: 1) daily time resolution for historical, nowcast, and intermediate-term forecast periods (1-day granularity, 1-hour cadence, and 1-hour latency extending 4.5 months); 2) high time resolution for recent, nowcast, and short-term forecast periods (3-hour granularity, 1-hour cadence, and 1-hour latency extending 96 hours); and 3) precision time resolution for recent, current epoch, and near-term forecast periods (1-minute granularity, 2-minute cadence, and 5-minute latency extending 6 hours). These indices and solar irradiances are used for improving atmosphere density and ionosphere models' outputs and we describe specific case studies as well as coupled applications that serve space systems users in orbit planning, satellite operations, and communication activities. For standards, we report on the activities of ISO TC20/SC14/WG4, which has the authority to develop international standards related to the space environment.
