Fastrax' IT900 RF module complements its software GPS receiver launched earlier this year.

The Fastrax IT900 essentially acts as an RF front-end for the Fastrax Software GPS receiver, converting a GPS RF signal into a digital intermediate frequency (IF) that is in-turn processed by the software receiver, according to the company.

Fastrax said its Software GPS has so far been ported to x86 and ARM processors and Windows, Windows CE, and Linux operating systems.

It can also be ported to additional processors, application-specific processors and operating systems, according to Fastrax.

The IT900 does not require any additional CPU or SRAM-memory for correlation, acquisition and tracking; once the IF signal is received from it, all remaining calculations are performed in the software, Fastrax said.

This includes signal correlation, acquisition and tracking, as well as pseudo-range calculations, navigation, and final PVT output, Fastrax added.
