The RGPSM001 GPS module from Racewood Technology is claimed to be the industry ’s lowest power GPS receiver module. Based on a high - performance, low - cost chipset from XEMICS, a Swiss fabless semiconductor company, the device features a power consumption of only 50 mW in tracking mode as opposed to a typical 100 to 200 mW for devices with similar levels of performance .
The low power of the GPS module is based on tight integration of its DSP and RF sub - modules. For example , the baseband advanced channel correlator IC consumes less than 3 mW, while the total RF+channel correlator solution is less then 25 mW. The optimizati on all ows a full PVT ( position velocity time) to be achieved in 50 mW for the GPS platform.
Powered by a powerful 32-bit ARM7-based microcontroller on board, with 128 Kbytes RAM and 512K bytes Flash, the GPS module further allows application customization for high volumes through masked ROM within the platform.
Despite consuming a low power of 17 mA at 3.3V, the module provides position accuracy of less than 3m and features high sensitivity of -143 dBm tracking resulting in good urban canyon performance. Designed to simplify the embedded system integration process, the ready - to - plug module provides warm starts under 42 seconds and hot starts under 10 seconds while also supporting bi - directional NMEA interf ace.
The baseband chip is packed in a 16-pin SO foo tprint, that facilitates the integration of GPS functionality into a variety of mobile devices without adversely affecting product form, factor and size. The RGPSM001 GPS Receiver targets use in automotive, handheld devices and local based tracking systems.
