Septentrio PolaRx2C L2C Receiver

Septentrio has developed a flexible FPGA extension platform to the existing PolaRx2 receiver, PolaRx2C, capable of receiving the coming L2C signals, that are part of the GPS modernisation. An important objective of GPS modernisation is to preserve civil use. The first stage in the GPS modernisation process has started in 2005, with the launch of the first satellite that will transmit civilian signals on the L2 band, called L2C signals. The L2C signals consist out of 2 PRN codes: the CM code and the CL code.

The PolaRx2C architecture results in a very low tracking noise. The design supports active multi-path mitigation, using both CM and CL and features modularity. The advantage of a combined platform, PolaRx2C, is that next to research on the first L2C signals, a complete dual-frequency P(Y) code receiver is offered. The L2C extension has the same high quality measurements (low noise, high sensitivity) as the standard PolaRx2 receiver.
