This helpful application can be used to select and look up GNSS frequencies and signal locations. The GNSS Frequency Guide is based on the LabSat 3 Wideband's integral web interface which enables you to setup and manage the GNSS testing program from a PC.
You can see a demo of the LabSat 3 Wideband Internal HTML Interface here.
Move the coloured bandwidth boxes in diagram above to change the centre frequencies, press the left mouse button and drag to left or right. Select your bandwidth, select your required frequencies and look up the available quantisation levels.
LabSat 3 Wideband has three bandwidth settings. 56 MHz, 30 MHz and 10 MHz.
The bandwidth of the GNSS signals varies, for example a GPS L1 C/A code signal has a bandwidth of 24 MHz. However, due to the signal design a bandwidth of 9.66 MHz will capture enough data to allow the receiver under test to acquire, track and navigate as with LabSat 3 single, dual and triple constellation devices.
Other signals with a different signal design like Galileo E1 PRS signal has a bandwidth of 46 MHz and a signal design spread across the bandwidth.
Many other signals have a similar requirement like GPS L1/L2 P code and M code. LabSat 3 Wideband has been designed to capture all these signals.
LabSat 3 Wideband is designed to capture and replay GNSS signals in the upper L-Band (1559 - 1610 MHz) and lower L-Band (1164 - 1300 MHz).
LabSat 3 Wideband can record and replay GNSS Signals at quantisation levels of:
