Study on high inclined elliptical orbiter aiming to support high data taransmision from ambulance

VHF模拟通信和NTT DoCoMo移动通信系统在救护车上的应用存在以下问题：在目前的地面无线通信环境下，我们无法为EMT提供合适的医疗控制，也无法避免救护车运输过程中出现的麻烦问题。例如，气管导管未插入食管，即使训练有素的EMT在VA中也有85%的失败率。为此，我们开始研究采用高倾斜椭圆轨道器的全国应急通信系统的可能性，旨在支持救护车的高数据传输。这些项目被调查。日本市区接收电源，来自HEO的信标；彗星卫星2号。日本城市地区360度光学相机能见度测量研制微波四象限探测器跟踪目标卫星。频率限制应答器的研究IMT-2000与HEO的比较急性心肌梗死医疗费用与heo7发射费用的比较。基于DSP技术的心电降噪采用高椭圆轨道卫星通信系统对4800辆救护车来说，可能比IMT-2000更具成本效益。未来，数据将从陆地移动设备实时发送，从而能够在运输过程中监测患者的病情；提供详细的数字运动图像，如光反射图像、损伤部位、气管内插管时声带图像、12张心电及超声心动图、饱和度等。这些传播可能会帮助病人。

VHF analog communications and NTT DoCoMo's mobile communication system are used on ambulance but they suffer from the following problems; 1) narrow band width, 2) multipath, 3) shadowing, 4) limited coverage Under the present wireless communication environment on the ground, we cannot provide a suitable medical control for EMT and cannot avoid troublesome problems during transportation on ambulance. For example, miss insertion of endotracheal tube into esophagus, even well-trained EMT performed 85% in VA. For this reason, we have started to study on possibility of nation wide emergency communications system with high inclined elliptical orbiter aiming to support high data transmission from ambulance. There items are investigated 1. Receiving power at urban area in Japan, beacon from HEO ; COMETS satellite 2. Visibility Measuring with 360 degree of optical camera at urban area in Japan 3. Development quadrant detector with microwave to track target satellite 4. Investigation on frequency limit transponder 5. Comparison between IMT-2000 and HEO 6. Comparison between medical cost of acute myocardial infarction and launching cost of HEO 7. Denoise of ECG with DSP technologyThe satellite communications system with High Elliptical Orbiter might be much more cost effective than IMT-2000 for 4800 ambulances. In the future, data will be sent in real time from land mobile unit, which enable monitoring patient conditions while in transit; providing detailed digital moving images such as light reflex images, injured site, vocal cord image during endotracheal tube insertion, 12 ECG with cardio echography, saturation levels, etc. These transmissions might help patients.
