Polar Telescience Via Satellite Communication Relay

9362197 DOUGLASS该项目将使用一个低高度、极轨道数据收集卫星平台，与商业通信卫星一起，直接在全球范围内恢复和分发来自现场仪器平台的数据。 它还为无人看管的平台的远程控制提供了一个命令链接。 该项目提供了一个负担得起的方法，大大提高了极地生物学。 这将大大提高通信能力，减少已部署系统数据恢复的延迟。 该计划的总体目标是与现有系统相比，将每日数据吞吐量提高100倍或更多。 预计的系统总成本使私营部门出资开发该系统并以收费服务方式运营成为可行。 第一阶段研究将（1）审查用户要求，（2）制定系统规格，（3）准备传感器平台和卫星设备的初步设计，（4）进行成本效益分析，包括预算寿命周期成本，（5）制定系统开发、模拟和演示的第二阶段计划。 这项研究将强调通过使用简单的传感器平台通信包、低成本的开发方案、经过验证的卫星部件和现有的经过验证的通信卫星系统来最大限度地减少系统的复杂性和成本。 ***

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. ***
