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

Two Active GLONASS Satellites Could Cause Users Difficulties

February 28, 2013By

On day 53 (February 22) around 09:15 GPS Time, GLONASS 743 began transmitting on frequency channel 6 using almanac slot 8 (R08). It should replace GLONASS 701K (801) transmitting on frequency channel -5, previously using almanac slot 8. However, GLONASS 701K was not immediately switched off and/or did not switch slot numbers and continued to transmit on frequency channel -5... read more
