This circuit comprises a satellite compass, a mini PC, two GPS antennas, power supplies, a network switch, media converters, and an atomic rubidium clock. The satellite compass is powered by a triple output DC power supply and interfaces with an RS232 splitter for 1PPS signals. The mini PCs are connected to the USRP B200 devices via USB for data and power, and to media converters via Ethernet, which in turn connect to a network switch using fiber optic links. The antennas are connected to the USRP B200s through RF directional couplers, and the atomic clock provides a 1PPS input to the RS232 splitter.

This circuit appears to be a complex system involving power supply management, GPS and timing synchronization, and data communication. It includes a SI-TEX G1 Satellite Compass for GPS data, an XHTF1021 Atomic Rubidium Clock for precise timing, and Ettus USRP B200 units for software-defined radio communication. Power is supplied through various SMPS units and distributed via terminal blocks and DC jacks. Data communication is facilitated by Beelink MINI S12 N95 computers, RS232 splitters, and a 1000BASE-T Media Converter for network connectivity. RF Directional Couplers are used to interface antennas with the USRP units, and the entire system is likely contained within cases for protection and organization.
