  About u-blox

u-blox is a leading fabless semiconductor provider of embedded positioning and wireless communication solutions for the consumer, industrial and automotive markets. Our solutions enable people, devices, vehicles and machines to locate their exact position and wirelessly communicate via voice, text or video.

With a broad portfolio of GPS modules, cards, chips, and software solutions together with wireless modules and solutions, u-blox is uniquely positioned to enable OEMs to develop innovative solutions quickly and cost-effectively. Headquartered in Switzerland and with global presence in Europe, Asia and the Americas, u-blox employs 200 people. Founded in 1997, u-blox is listed on the SIX Swiss Exchange.



u-blox provides highly integrated solutions for embedded GPS and wireless applications. Our market-proven products can be found in demanding automotive and industrial environments, as well as in mobile and handheld consumer devices where size, performance and power consumption are critical.

Combining industry-leading sensitivity and noise suppression with innovative features and packaging, u-blox products are designed to meet our customers stringent requirements. Whether as GPS or wireless modules, chips or complete GPS or wireless solutions, we offer the right solution with the right performance to suit your designs.

- AssistNow Online

With AssistNow Online, a GPS device with mobile or Internet connectivity accesses and downloads assistance data from our Global Reference Network of GPS receivers at system start-up.

Employing User Plane communication and open standards such as TCP/IP, AssistNow Online works on all standard mobile communication networks that support Internet access, including GPRS, UMTS and Wireless LAN. No special arrangements with mobile network operators are needed to enable AssistNow Online, making this solution network operator independent and globally available. u-blox only sends Ephemeris data for those satellites currently visible to the mobile device requesting the data, thus minimizing the amount of data transferred.


- AssistNow Offline

With u-blox' AssistNow Offline service, users can download Differential Almanac Correction Data from the Internet or wireless network at their own convenience from anywhere in the world. Afterwards the GPS device requires no connectivity at system start-up, thus enabling users to enjoy instant positioning, even when no network connection is available.

Users can download Differential Almanac Correction Data files anytime they have an Internet connection, for example at home, in the office or through a wireless network such as GPRS, UMTS or a Wireless LAN. The correction data is then downloaded to the mobile terminal via TCP/IP, serial port, memory card, etc, and can be stored in the GPS receivers Flash EPROM (if available) or in the memory of the application processor.

u-blox provides Differential Almanac Correction Data files with corrections valid from 1 to 14 days. The size of these files increases with the length of the prediction period, from as little as 3 KB to 90 KB. Positioning accuracy decreases with the length of the correction file duration, with 1-3 day files providing relatively high accuracy and 10-14 day files progressively less accuracy. Regular updates help to ensure a high level of position accuracy.
