Polar Telescience Via Satellite Communication Relay

道格拉斯该项目将使用低空、极轨道、数据收集卫星平台，与商业通信卫星一起，提供直接的全球范围内的原位仪器平台数据恢复和分发。它还为无人值守平台的远程控制提供了命令链接。这个项目提供了一个经济实惠的方法，大大提高了极地科学。它将显著增加通信容量，减少部署系统的数据恢复延迟。与现有系统相比，该计划的总体目标是将每日数据吞吐能力提高100倍或更多。由于预计的系统总成本，可以利用私营部门的资金开发该系统，并在按服务收费的基础上运作。第一阶段研究将(1)审查用户需求，(2)制定系统规范，(3)准备传感器平台和卫星设备的初步设计，(4)执行成本效益分析，包括预算生命周期成本，以及(5)制定系统开发，模拟和演示的第二阶段计划。该研究将强调通过使用简单的传感器平台通信包、低成本开发选项、成熟的卫星组件和现有的、成熟的通信卫星系统进行数据分发，使系统的总复杂性和成本最小化。＊＊＊

9362197 DOUGLASS This project will to use a low altitude, polar-orbiting, data collection satellite platform, in conjunction with commercial communication satellites, to provide direct worldwide recovery and distribution of data from in-situ instrumentation platforms. It also provides a command link for remote control of the untended platforms. This project offers an affordable approach to greatly improved polar telescience. It will significantly increase communication capacity and reduce delays in data recovery for deployed systems. The overall objective of the program is to increase the daily data throughput capability by a factor of 100 or more, compared to existing systems. The anticipated total system cost makes it feasible to develop the system with private sector financing and operate it on a a fee-for- service basis. The Phase I study will (1) examine user requirements, (2) develop a system specification, (3) prepare a preliminary design of the sensor platform and satellite equipment, (4) perform a cost effectiveness analysis, including budgetary life cycle costs, and (5) develop a Phase II plan for system development, simulation, and demonstration. The study will emphasize minimization of total system complexity and costs by using simple sensor platform communication packages, low cost development options, proven satellite components, and existing, proven comsat systems for data distribution. ***
