英文要約SBIR technological innovation business in 2008 fiscal year "Feasibility study of small GPS receiver for space"
The GPS receiver for the spaceborne already exists. However, it is expensive, and large-scale with several hundred million yen. Moreover, the content is not disclosed. Therefore, it became a problem in the development of the satellite. It was necessary to develop low-priced GPS receiver for space use.In this business, the feasibility study was done as follows. We set up the prospect of achieving these. a.)The adaptability of the navigation processing algorithm (GRAPHICS) and the characteristic of the projected GPS receiver is analyzed, and verified. And, we set up the prospect of achieving high accurateness (about 10cm/s -> 1cm/s) b).We confirm that built-in computer in projected GPS receiver can process navigation processing algorithm.As a result, we sets up the prospect of achieving the miniaturization and lightening. (one-unit (excluding power unit): about 1kg or less) c).It was achieved to lower the cost by the above-mentioned:(price (including development cost):about 60 million yen, equipment complete set price (excluding power unit ):10 million yen or less) Spacelink Ltd. executed the following content.1). Document study For the performance and the function of a small GPS receiver for space, 2). We have done market study and reflected the result in specification. 3). We investigate the best specification . 4). The structure of hardware and software of small GPS receiver for space are investigating. 5). Development plan is investigated 6). Result report is being made
