Satellite technology is changing constantly. Israel plans to put up a commercial satellite this year which will be five times as precise as the best existing satellite, nearly as clear as a spy satellite. Taiwan has already signed up to receive images. Also, several private corporations in the US will soon enter the satellite market.
衛星科技日新月異，以色列即將在今年發射的衛星，其解像度比目前最精準的衛星還要高五倍，幾乎像偵察衛星一樣清楚，太遙中心已經簽了約準備接收；美國也有幾家民營衛星即將投入空中市場。
