PocketSDR GNSS receiver
This is an implementation of Prof. T. Takasu's open-source project PocketSDR GNSS on GitHub. This device is manufactured in full accordance with the schematics provided by the open-source project and is a 4-channel version, meaning it includes 4 Max2771 RF front ends.
It supports almost all GNSS frequency bands and satellite systems.
The following technical specifications are extracted from the GitHub repository Pocket SDR GNSS.
Pocket SDR FE 4CH is an open-source GNSS SDR RF frontend device for Pocket SDR. The device consists of 4 CH Maxim MAX2771 ([1]) GNSS RF front-end ICs (LNA, mixer, filter, ADC, frequency synthesizer) and a Cypress EZ-USB FX3 USB 3.0 controller ([2], [3], [4]) to connect to host PCs. All the RF CHs are able to be configured for GNSS L1 band (1525 - 1610 MHz), or GNSS L2/L5/L6 band (1160 - 1290 MHz). The frequency of the reference oscillator (TCXO) is 24.000 MHz, and the ADC sampling rate can be configured up to 48 Msps.
