The actual limits are as follows: US export restrictions limit most receivers to 60000 ft or 18000 m. US export restrictions limit most receivers to 999 kts or 515 m/s. So, you could theoretically go faster than 1000 knots if you were under the 60.000 foot limit, but most GPS's enforce the limit for either violation. Also, as I understand this (from doing research lately), all consumer-grade GPS receivers enforce the limit, since I doubt any consumer needs to worry about going faster and/or higher than the limits.
