![]() ![]() Some USRP models also provide the option to stream 8-bit samples, effectivelyĭoubling the host-bandwidth in terms of samples/second. Refers to the sample stream between the FPGA of a USRP device, and a host PC. Rate provided by the ADCs on the USRP motherboard, and the host sample rate The ADC processing bandwidth is the sample Model you are using, the configuration may vary (see below). Any model will fit, just check that you can plugĪ USRP. In order to get real-time position fixes, you will need:Īn active GPS antenna. complex samples), and using a device from the USRPįamily as the “air-to-computer” interface. This is an example of an eight-channel GPS L1 C/A receiver, working at 4 MS/s The antenna without harming the front-end, plus an adequate power source (GNSSĪntennas use to be fed in a range from 2.5 VDC to 5.5 VDC, please check your The antenna cable or some other kind of protection in order to inject power to If this feature is not available, you will need a bias-T in ![]() Some radio frequency front-ends have jumpers, or some other configurable mode,įor antenna feeding. Live signal samples delivered by a radio frequency front-end, you will need anĪctive antenna (that is, an antenna with an integrated low noise amplifierĭelivering a gain in the band of interest greater than \(20\) dB, with a noiseįigure below \(2\) dB), and you will need to feed it. Post-processing, or if you are configuring a receiver to work in real-time with Important note: Either if you are capturing signal in a file for Tips for obtaining position fixes (and a collection of side data, delivered in Page describes examples of hardware setups, software configurations, and general Software-defined receiver is to play with live GNSS signals in real-time. Obtaining position fixes from a file is nice and useful, but the real deal for a ![]()
