这是来自gps系统的应用限制。从原理或者硬件能力角度来说呢？


【 在 PaoloMaldini 的大作中提到: 】
: 搜了下还挺有意思的：
: In GPS technology, the term "CoCom Limits" also refers to a limit placed on GPS receivers that limits functionality when the device calculates that it is moving faster than 1,000 knots (1,900 km/h; 1,200 mph) and/or at an altitude higher than 18,000 m (59
: ,000 ft).[4] This was intended to prevent the use of GPS in intercontinental ballistic missile-like applications.
