Magellan(R) GPS IP Now Available Directly From Atmel
The Baldur GPS baseband IC achieves horizontal resolution of as little as one meter, corrected, and three meters, autonomous. Vertical resolution is five meters (corrected) and velocity is measured to within 0.1 meters/second. The chip's superior acquisition (-137 dBm) and tracking (-150 dBm) sensitivities are possible because Baldur can receive and process signals from as many as 12 different tracking satellites at the same time. Additionally, it has two Satellite-Based Augmentation System (SBAS) channels for Wide Area Augmentation System (WAAS), European Geostationary Navigation Overlay Service (EGNOS) or Multi-functional Transport Satellite Augmentation System (MSAS). The maximum position update rate is once per second.
Developed specifically for portable handheld applications, Baldur dissipates only 70 mW under continuous operation at 16 MHz, and 18 mW in power-saving mode. Battery life for an eXplorist device is 14 hours. Baldur's time-to-first-fix (TTFF) signal acquisition takes less than 90 seconds from a cold start, 30 seconds from a warm start and only 15 seconds from a hot start. Once fixed, signal reacquisition takes less than a second.
According to Bill Gross, Atmel's GPS Marketing Manager, "Never before has such a fully-featured GPS baseband been available at such a competitive price. Competing GPS baseband ICs with comparable sensitivity and accuracy typically costs about $9 with a total chipset price of about $17. Until now, GPS technology had been limited to expensive, high-end equipment such as luxury cars, premium mobile phones and PDAs. GPS is a huge, rapidly growing market," Gross added. "By 2008 $10 billion of in-vehicle navigation systems and $1.3 billion of GPS-based asset tracking systems are expected to be sold. Baldur's $5 price is going to help accelerate this growth, opening a floodgate of new GPS product designs and making GPS technology pervasive in cars, mobile phones, PDAs and other personal tracking devices. We wouldn't be surprised to see GPS systems in kid's lunch boxes and dog collars."
Pricing, Packaging and Availability
Baldur, part number ATR0640, is available now in a 12mm x 12mm LFBGA package. It is priced at $5 in quantities of 100,000. Atmel expects to offer complete GPS chipsets with Atmel's radio receiver chips for less than $8 by the third quarter of 2005.
(1) A global positioning system (GPS) is a satellite navigation system using a constellation of 28 satellites to provide accurate determination of location. GPS systems are used for aviation, communications, in-vehicle navigation, marine, military, people tracking, recreation surveying and mapping, timing and vehicle and freight tracking. Although signals from as few as two satellites can be used to determine a location, accuracy increases linearly with the number of different satellite signals processed. Accuracy can also be improved by applying correction algorithms to signals from the Wide Area Augmentation System (WAAS), European Geostationary Navigation Overlay Service (EGNOS) or Multi-functional Transport Satellite Satellite Augmentation System (MSAS). Using current technology most GPS systems can resolve a location to within about three meters. However, it is possible to achieve resolution of a few centimeters (e.g. surveying applications).
