DYNAMICALLY UPDATING A TIME INTERVAL OF A GPS |
| 摘要 |
A seismic system includes a wireless sensor node. The wireless sensor node includes a global positioning system (GPS) device to receive a GPS time value at an interval; a temperature sensor to measure temperature; an oscillator to measure time; and a memory to store the GPS time value, the temperature, and the oscillator time. The wireless sensor node also includes a processor to determine a rate of temperature change during the interval, and to dynamically update the interval to receive the GPS time value from the GPS device, based on the rate of temperature change. |
