GPS Receiver Sets Power Benchmark

Enlisting a SiRFstar III chipset, the hardware revision 04 of the A1080-A GPS receiver operates from a 3.3V supply and draws 23 mA at one fix per second (average) and 32 mA (maximum) during satellite acquisition. Reportedly, this power performance outperforms comparable stand-alone GPS receivers by 50%. Embedded into applications, users can reduce power consumption even further by using two low power modes. The adaptive-trickle-power mode drives down the processing power by maintaining periodic and accurate position output. In push-to-fix mode, the module goes to sleep and keeps the ephemeris updated automatically. Additionally, the module’s stand-alone design requires only a single power supply, an antenna, and a standard serial interface for operation and no other external components are necessary.
