SBIR Phase II: Airborne Science Data Relay Using ORBCOMM

9509059 兰福德 这是一个小型企业创新研究第二阶段的奖项，以支持一个项目，以开发和展示一个双向，低成本的机载科学数据中继。 该公司确定了为科学飞机提供轻型、低成本、双向通信链路的需求。 该项目的第一阶段调查了大气科学用户对数据中继和使命控制的要求。 利用低地球轨道通信卫星满足这些要求的可行性已通过对一个黄铜板系统的地面测试得到证明。 在演示该系统时，发现直接将数据中继到第一颗可见卫星并不总是提供最短的信息传输时间。 为了确保最及时地提供科学和使命数据，开发了一个供ORBCOMM系统使用的“SmartLink”调度程序。 第二阶段将实现实时版本的调度器，将系统安装到无人机通信包中，并进行超视距飞行测试。 集成到ORBCOMM收发器中的SmartLink调度器将首先用于无人驾驶科学飞机;然而，它也可以为有人驾驶飞机提供低成本的互联网链接。 任何需要低成本、短延迟、与远程站点进行Internet通信的操作都将受益于此产品，并且是潜在客户。

9509059 Langford This is a Small Business Innovation Research Phase II award to support a project to develop and demonstrate a two-way, low-cost airborne science data relay. The company identified a need for a lightweight, low-cost, bi-directional communications link for science aircraft. Phase I of the project investigated atmospheric science user requirements for data relay and mission control. The feasibility of using low-Earth orbit communications satellites to meet these requirements was demonstrated through ground testing of a brassboard system. In demonstrating this system, it was discovered that straightforward data relay to the first visible satellite does not always provide minimum message transmission time. In order to ensure the most timely delivery of science and mission data, a "SmartLink" scheduler for use with the ORBCOMM system was developed. Phase II will implement a real-time version of the scheduler, install the system into a UAV communications package, and conduct over-the-horizon flight tests. The SmartLink scheduler, integrated into ORBCOMM transceivers, will be used first for unmanned scientific aircraft; however, it also can provide a low-cost Internet link for manned aircraft. Any operation requiring low-cost, short latency, Internet communication with a remote site will benefit from this product and is a potential customer.
