So, here am I. It's been a week since I bought the GlobalSat SiRF IV BT-354S4 and finally, after some days of struggling to make it work, I realised I MADE A BAD CHOICE NOT TO READ THE GPSD FORUMS.
Your possible problem; NO FIX/ BAD FIX
you order
$ gpspipe -r -n 10
or
$ cgps
or
$ gpsmon -n
to test if your receiver works and the terminal results only to this{"class":"VERSION","release":"3.22","rev":"3.22","proto_major":3,"proto_minor":14}
{"class":"DEVICES","devices":[{"class":"DEVICE","path":"/dev/ttyUSB0","activated":"2021-04-23T14:35:07.390Z","native":0,"bps":9600,"parity":"N","stopbits":1,"cycle":1.00}]}
{"class":"WATCH","enable":true,"json":false,"nmea":true,"raw":0,"scaled":false,"timing":false,"split24":false,"pps":false}
But the device's light is blinking what can I do? Well assuming that you have searched your way here to find a solution I assume that you have took all the necessary steps for the installation and configuration of gpsd with your device(if not, I will explain further, later, below). The solution is: patience<em>. YES, </em>patience, no jokes; wait at least 15-20 minutes for stable fix. I'll explain below.
This thing does not work like your WiFi in your home, where for example, you plug the 802:11 adapter in your PC/Laptop/Potato and it takes like 10 seconds to scan, find and connect to a network.
GNSSs receivers, (especially our ☭ device, the GPS GlobalSat SiRF IV BT-354S4) works with the satellites.
At least 4 satellites are needed for a precise location within 5-8 meters. The more satellites the better. A lot of satellites, can get your exact position within inches.
Of course there is not only that GlobalSat device. There are many systems and devices.
In this

you can see which devices are recommended, bad, broken and more in gpsd official website.
Here are the satellite systems that the receivers work with; some work with all together, some with one or the other and some with a single one
<strong>The G</strong><em><strong>lobal Navigation Satellite System (GNSS)</strong></em>
Global Positioning System [GPS] (United States)
GLObal NAvigation Satellite System [GLONASS] (Soviet Union/Russia) [Not to be confused with GNSS]
