Evaluation Kit by NVS Tecnologies

April 1, 2013By

Evaluation Kit NV08C-EVK-CSM by NVS Technologies is a set of instruments for a developer of systems based on NVS Technologies’ NV08C-CSM module. Use of EVK-CSM is a convenient way to learn functionality of NV08C-CSM and begin system design. The EVK-CSM may be used in navigation systems to obtain the current position (latitude, longitude and elevation), velocity vector, and time GNSS... 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
