Updated July 2009 - ST Microelectronics have just announced a new version of their GPS enabled Cartesio platform used on several Garmin receivers (see http://www.gpspassion.com/fr/articles.asp?id=259) : Cartesio+. Full PR is here : http://www.st.com/stonline/stappl/cms/press/news/year2009/p2404.htm and the spec sheet is here : http://www.st.com/stonline/products/families/gps/cartesiop.htm
I was thinking it might already be powering the new line of Garmin nuvi 1xxx systems but volume production won't start until December 2009.
Posted August 2007 - A press release today (see below) from ST Microelectronics to announce that Garmin will be using their Teseo chipset in "certain Garmin Portable Navigation Devices (PNDs) and handheld GPS receivers".
A few comments :
1. It could well be that the Garmin "Bravo" chipset used on some recent Nüvi 2xx AIOs is in fact based on ST's Teseo engine, good sensitivity but uneven tracking compared to SiRFstarIII, as seen >> HERE <<
2. Delorme has been using ST chipsets since the LN-20 in 2005 and again on the PN-20 portable system in 2007 with a sensitivity that is slightly below that of SiRFstarIII. It's possible that the Teseo is a new version that will premiere on the Garmin devices.
3. The SiRF stock lost 9% on the news, i.e. $1.67 at $17.76
Garmin Integrates New GPS Chipset from STMicroelectronics
GENEVA, Aug. 23 /PRNewswire-FirstCall/ -- STMicroelectronics , a world leader in automotive semiconductors, today announced it has launched volume production of its Teseo GPS engine designed for use in certain Garmin Portable Navigation Devices (PNDs) and handheld GPS receivers.
"We are proud to announce that our state-of-the-art GPS technology has been selected for Garmin's new range of portable and handheld devices," said Domenico Rossi, General Manager of ST's Car Radio and Multimedia Division. "ST is one of the few players in this market that can offer high-performance and cost-effective GPS solutions, based on robust silicon technology, experience in the automotive market, and know-how developed in collaboration with leading navigation manufacturers."
ST's Teseo platform is a turn-key solution that combines reliability and cost-effectiveness with enhanced performance and extended functionality.
Superior tracking sensitivity is vital for Portable Navigation Devices that have the antenna inside and their satellite visibility is further deteriorated by the "shield effect" of the car front window. The integration of ST's newest GPS solution improves tracking in poor satellite visibility conditions and shortens GPS signal acquisition times.
ST Teseo's TTFF (Time To First Fix) values, the time it takes a GPS receiver to find satellites, rank among the fastest in the industry. A "warm start" -- the acquisition of accurate time, satellite positioning and velocity (ephemeris) data that have been lost during the switch-off -- takes less than 34 seconds.
ST's new GPS chipsets support satellite-based augmentation systems such as WAAS (Wide Area Augmentation System) and EGNOS (European Geostationary Navigation Overlay Service) that provide additional accuracy and reliability. Teseo's GPS accuracy expressed in circular error probability (the radius of a circle that represents a 50% probability of a position lying in that circle) is as low as 2 meters. ST's Teseo devices are ready for compliance with Galileo, the upcoming European navigation system complementary to GPS.
ST's Teseo solution integrates a high-sensitivity single-chip baseband (STA2058) with embedded flash and an RF front-end (STA5620), complemented with full software libraries. The product is available both in a single-package form (STA8058) and as a dual-chip offering. ST designers are currently working on a System-on-Chip solution that integrates the Teseo GPS engine and an ARM9 core for GPS navigation processing.
The embedded flash memory enables the equipment manufacturer to load the entire GPS software. The TESEO GPS baseband IC integrates a rich set of peripherals, including a CAN 2.0 B active interface, a four-channel 12-bit A/D, I2C (Inter-IC), UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), GPIO (General Purpose Input / Output), and USB.
ST's Teseo platform addresses a wide range of applications, including Personal Navigation Devices and handheld GPS receivers, in-car navigation, telematics and electronic toll collection.
