 Until recently, satellite receiver chipsets were designed specifically for only one satellite system. With the release of STMicroelectronics single-chip positioning device, the Teseo II, handheld and personal GPS can be used universally. This device works similar to the GSM coverage for cell phones. The Teseo II is able to track satellites in the following systems: GPS (North America), GALILEO (Europe), GLONASS (Russia) and QZSS (Japan). With the ability to access all the major satellite constellations, the Teseo II outshines all other GPS receivers. Position, velocity and time information can be drawn from the satellites. The variety of satellites to choose from ensures the data will be far more accurate in obstructed areas, like urban centers or mountain ranges. This new technology is a great cost-effective measure for positioning devices. Future navigation aids will benefit largely from the replacement of current single-system positioning devices with the Teseo II receiver. |
