GPS module consumes only 21mA in tracking mode

June 03, 2013 // By Julien Happich
MSC now offers the new L26 multi-GNSS module from Quectel, featuring an ultra-low power consumption of only 21mA in tracking mode and drawing 29mA in acquisition mode, with a sensitivity of -165 dBm in tracking operation and -148dBm in acquisition operation.

The L26 module is based on the MediaTek MT3333 chip and has 99 acquisition and 33 tracking channels. It enables the simultaneous use of the U.S. Global Positioning System (GPS), the globally available Russian counterpart Global Navigation Satellite System (GLONASS) and the Japanese Quasi-Zenith Satellite System (QZSS). The high number of available satellites, the Multi-tone Active Interference Canceller (MTAIC) function for efficient elimination of narrow band interference and noise integrated on the MT3333 and the likewise integrated very low-noise amplifier not only ensure rapid first fixes, but also high positioning accuracy.

Thanks to EASY (Embedded Assist System), an Assisted GPS technology developed by MediaTek and an innate logger function implemented on the MT3333 chip, no additional external memory is required for safe operation of the L26 module. The 16.0x12.2x2.4mm module has a wide operating temperature range from -40°C to +85°C suited for use in a wide range of consumer, automotive and industrial applications.
