NASA-艾姆斯研究中心与通用原子航空系统公司合作，一直在开发实时数据采集和信息传输系统，采用无人飞行器 (UAV) 技术进行减灾和评估演示。我们与负责野火管理和缓解的灾害社区机构美国林业局合作，开发了名为“第一响应实验”(FIRE) 的大规模野火演示。在 2001 年夏末的实验中，参与者展示了无人机平台、实时数据处理和数据遥测等创新技术的融合，以快速分析灾难事件。在受控燃烧中使用了通用原子公司 ALTUS 无人机、机载红外灾害评估系统 (AIRDAS) 和超视距 (OTH) 卫星数据遥测设备，以测试危险任务灾害监测和缓解平台的可行性。 ALTUS 无人机用于演示无人平台获取灾害相关数据的长持续时间、高度和有效载荷能力。 ALTUS 的工作高度可达 45,000 英尺（13,700 英寸），飞行时间为 24 小时，有效负载能力超过 300 磅。 （148.5 公斤）。这使得该平台能够在监测和减轻美国各地灾害事件所需的条件下运行。四通道 AIRDAS 数据（火灾事件的校准热红外数字图像）从 ALTUS 无人机通过卫星通信系统（NERA 转发器和 INMARSAT 卫星）发送到 400 英里外 NASA-Ames 研究中心的数据存档服务器和图像处理工作站。
NASA-Ames Research Center, in collaboration with General Atomics Aeronautical Systems, Inc. has been developing real-time data acquisition and information delivery systems employing uninhabited aerial vehicle (UAV) technology for disaster mitigation and assessment demonstrations. Working in conjunction with the US Forest Service, a disaster community agency responsible for wildfire management and mitigation, we developed a large-scale wildfire demonstration called the First Response Experiment (FIRE). During that experiment in late summer 2001, the participants demonstrated the melding of innovative technologies such as UAV platforms, real-time data processing, and data telemetry for quick analysis of a disaster event. The General Atomics ALTUS UAV, the Airborne Infrared Disaster Assessment System (AIRDAS) and Over-The-Horizon (OTH) satellite data telemetry equipment were employed over a controlled burn to test the feasibility of a disaster monitoring and mitigation platform for hazardous duty. The ALTUS UAV was employed to demonstrate the long duration, altitude, and payload capability of unmanned platforms for acquiring disaster related data. The ALTUS has an operational altitude to 45,000 feet (13,700 in), with a flight duration of twenty-four hours and a payload capacity of over 300 lbs. (148.5 kg). This allows the platform to operate under the conditions that would be necessary for monitoring and mitigating disaster events throughout the Unites States. The four channel AIRDAS data (calibrated thermal infrared digital imagery of the fire event) was sent from the ALTUS UAV via a satellite communications system (NERA transponder and INMARSAT satellite) to a data archive server and an image processing work station at NASA-Ames Research Center, 400 miles away.
