I have no clue about the ‘BU-353S4’ or even the better ‘BN-85U’ 🙂 I used a Sirfstar III chipset for GPS, fourteen years ago. So I was checking out this GPS receiver on Ali express with this promising title: “BEITIAN Auto-adapted baud rate USB GNSS GPS Receiver 1Hz 4M FLASH 5.0V Double-sided tape NMEA-0183 BN-85U better than BU-353S4” I wanted to experiment with GPS over USB cable. Within my family we easily reach up to 12 systems with free and accurate global positioning. Just count the number of GPS receives you have in your mobile devices, car or even your pets collar. I still have warm feeling about what I managed to do back then… A GPS was not built in by default in those devices. Back in 2005 already, I did some projects with tracking vehicles using a ‘GPS mouse’ and smart phones with GPRS. I have always have had a sweet spot for GPS technology.
