New GPS firmware with SBAS support and high sensitivity

28 January 2004 Telecoms, Datacoms, Wireless, IoT

u-blox, has introduced a new version of its ANTARIS GPS Software that it says features high sensitivity, multiple SBAS support, full aiding functionality and improved performance in areas with limited satellite visibility.

The ANTARIS GPS Firmware for u-blox GPS receiver products and the chipset jointly developed with Atmel is now capable of receiving SBAS (satellite-based augmentation systems) signals from multiple geostationary satellites simultaneously such as WAAS in the USA or EGNOS in Europe. These systems provide integrity and correction information like ionosphere activity and generate ranging signals like GPS satellites. The GPS receiver can use these additional satellites to improve navigation accuracy significantly thanks to its 16 channels architecture.

The firmware release 3.0 now provides significantly higher sensitivity without any compromises. The GPS receiver starts losing track at -150 dBm only, allowing navigation in difficult environments like urban canyons and under dense foliage, and enables applications with concealed antennas. In addition, enhancements in the navigation software detect and eliminate multipath effects in urban canyons and improve overall navigation accuracy, especially under dynamic conditions.

"The innovation leaps in the new firmware are proof of the high standing capabilities of u-blox and are beneficial to existing as well as new applications without any additional cost," says Thomas Seiler, CEO of u-blox. "Also, our customers can rely on high quality GPS receiver platforms and profit from the continuously upgraded performance with the additional feature sets."
