A New Approach to the Design and Development of Global Navigation Satellite Systems
In this month’s column, a team of authors affiliated with the Galileo project discusses the Interface Communication Modeling Language, an extension of UML that allows engineers to clearly represent SIS interfaces, critical for the design of GNSS receivers. read more

Building a Wide-Band Multi-Constellation Receiver

March 1, 2013By
G-opener

The authors designed a full-constellation GNSS receiver, using a cost-effective, readily available, flexible front-end, wide enough to capture the frequency from 1555 MHz to 1607 MHz, more than 50MHz. This spectrum width takes into account BeiDou E2, Galileo E1, GPS L1, and GLONASS G1. In the course of their development, the authors used an external OCXO oscillator as the reference clock and reconfigured the platform, developing their own custom wide-band firmware. read more

Expert Advice: BeiDou, How Things Have Changed

February 1, 2013By

Economically, the System Differs Significantly from Its GNSS Cousins John W. Lavrakas In May 2007, I authored an article in GPS World looking ten years into the future and envisioning how the GNSS field would operate at that then-distant time. Reviewing my assessments, I see that I was both accurate and wide of the mark with my predictions. The prediction... read more

A method of decoding an unknown pseudorandom noise code uses a conventional GNSS antenna and receiver with modified firmware. The method was verified using the signals from the Galileo In-Orbit Validation satellites. read more

u-blox Demonstrates Navigation Using BeiDou

January 18, 2013By

Swiss-based u‑blox, a provider of GPS/GNSS and wireless semiconductors, has achieved successful satellite positioning using China’s BeiDou Navigation Satellite System. According to u-blox, the technical achievement establishes u-blox as the first GNSS component vendor to demonstrate compatibility with all globally deployed positioning systems: GPS, GLONASS, Galileo, QZSS and now BeiDou. However, NovAtel has also announced support for the BeiDou Navigation... read more
