STM debuts single-chip for GPS, GLONASS, Galileo and QZSS

STM-Teseo-IIST Microelectronics has announced the Teseo II chipset family, the first capable of receiving GPS, GLONASS, Galileo and QZSS signals.

As GLONASS and Galileo begin to offer global coverage, the use of multiple-positioning systems promises improved performance in difficult environments such as urban canyons, as well as greater accuracy.

Samples of the first chipset in the Teseo II family, the STA8088EX, are available now, with volume production scheduled for Q3 2011.

Here’s the full news release.

  1. Is this the chip used in the Garmin eTrex 30.

  2. Is this the chip used in the Garmin eTrex 30.

    • Probably. It’s certainly been widely reported on’s message board that it is, but I don’t recall anything from Garmin or STM that said so.

      • Thank you for the reply. I really baffles me why Garmin does not state this under their specification.

        • Yep, not exactly a trade secret when any competitor can buy one, take it apart and figure it out.

          • Yeah that was my next step. But I worry that I break the magical Garmin waterproof seal. They don’t exactly go out of their way to make their devices waterproof. So any disturbance of the seal weakens it (or so I feel). Now just hope Garmin is interested in this model long enough for more updates to follow. Like Glonass only operation and supporting QZSS when operational.
