SYSTEM AND METHOD FOR COMPRESSING GPS DATA |
摘要 |
A system and method are provided for compressing global positioning system (GPS) data. The method includes determining a first GPS position and an associated first time; incorporating the first GPS position and the associated first time in a GPS update packet; determining a time interval for a set of GPS positions subsequent to the first GPS position and specifying the time interval in the GPS update packet; and for each of the set of GPS positions subsequent to the first GPS position: computing a relative latitude value and a relative longitude value; compressing the relative latitude and longitude values by reducing precision; and storing compressed relative latitude and longitude values in the GPS update packet. There is also provided a system and method for decompressing such compressed global positioning system (GPS) data. |
